Picture of Acer Extensa Laptop (5620 / T5250) Upgrade & Tweak Guide

Some time ago I posted about installing Windows XP onto my new Acer Extensa 5620-6830 laptop. It's a nice little machine- the price was right, and standard specs aren't bad. But here's some information that could be helpful to anyone with this budget best Buy laptop and wants to get the most bang for their buck!

This guide will cover tips for upgrading, maintenance, plus tweaks and tricks specific for this and other similar model laptops. Learn how to double your battery life, what hardware can be replaced, and if it's smart to do so. In conjunction with my other Instructables, this has some valuable tidbits specific to notebook computers.

6.Final thoughts

Step 1: Memory (RAM & Hard Drive)

Picture of Memory (RAM & Hard Drive)

The Extensa 5620-6830 comes with 1GB of DDR2 memory. That's two sticks of 512MB. This unit technically supports 4GB; 2 x 2GB modules. However, unless you're running a 64-bit operating system (if you have to ask how you'd know, trust me... you're not) then only about 3GB will be usable. There's no fix for this, it's just a fact. All standard 32-bit operating systems are coded this way.

Due to this, I decided to purchase two 1GB modules (making 2GB total). I find that to be plenty sufficient; I've never run out of memory in XP. Keep in mind, Vista will use about 1GB just to boot and run. You'll want to buy 667Mhz modules. There are 800MHz modules out there, but 99% of laptops on the market can't operate at that frequency. You'd be paying extra money for nothing, plus risking incompatibility.

There is an obvious single "hatch" on the bottom of the unit through which we access nearly everything- wifi card, RAM, hard drive, and CPU. You'll need a small philips-head screwdriver to open this. You shouldn't have to apply force once the screws are out, though take note of the plastic tabs along one side.

The stock hard drive is a TOSHIBA MK2035GSS 200GB drive. It runs at 4200RPM, has an 8MB Cache, and uses Perpendicular Magnetic Recording (PMR) combined with Tunnel Magneto-resistive Recording (TMR) Head Technology. All that jargon supposedly means it's roughly as fast as a 5400rpm drive. I find it acceptable. There's faster drives out there, but is it worth wasting the $165 on a 200GB 7200rpm drive just to replace the original 200GB? You'd see a lot more heat, less battery life, and a big chunk out of your pocketbook.

The choice is yours, but I'm waiting for a faster (or equivelent-speed) 320GB drive.

Step 2: Bluetooth/Wifi

Picture of Bluetooth/Wifi

While our 5620 has a front switch and light for Bluetooth, the actual module is not installed. Supposedly you can get one from Acer themselves... but be prepared to pay a small fortune. And know the part number. And likely have it shipped overseas.

There's two options for adding Bluetooth. If you're going to wait for overseas shipping anyway, why not buy a cheap ($6.99) little low-profile USB bluetooth adapter from DealExtreme (which works fine under both Windows and Mac). It takes awhile to arrive, but the one I got was cheap and works great. Best of all you don't have to crack your laptop open.

Oh, not scared of taking apart your Acer? Okay then. Roughly under the mousepad on the top of the motherboard is a small four-pin plug. If you can find a small plug to fit it, and are decent with a soldering iron, then you can modify a USB Bluetooth adapter to fit here. An easier way is to buy this pre-made off eBay for about $25. Just do a search for "acer bluetooth," and make sure the plug has a four-pin.

Why do you need Bluetooth? You don't. But it can be nice for transferring file to and from your cellphone, or using a wireless mouse. Plus it makes that switch on the front of your laptop actually do something!

The Wifi card is an Intel 3945 802.11a/b/g Mini-PCIe (PCI Express) card. It works just fine, but eventually you could switch to an 802.11n one to match your newer router if you wish. I ended up swapping mine out with a spare 802.11b/g Atheros card from a junk Toshiba for my own reasons; the good news is, there's no Bios whitelist issue that stops other cards from working.

Step 3: CPU (hardware)

Picture of CPU (hardware)

The stock CPU, at first glance, is nothing special. It's a Intel Core 2 Duo T5250; that's 1.5GHz on a 667MHz bus with a 2MB L2 cache. It uses the new Socket P design, however. That's a good thing for a number of reasons.

This uses the Meron core, and supports a bus up to 800MHz. That means for $250-ish, you can replace your T5250 with a T8300- that's 2.4GHz, a 3MB cache, and a decent FSB bump. They both run at 35W, so in theory your battery life and heat output won't suffer. The T8300 is also a 45 nm cpu, as opposed to the original 65 nm T5250. This specific upgrade has been reported to really beef things up- even Vista goes from 4.x to 5.x scores.

If that's a bit too pricey for you, save $40 and grab a T8100. That ones a 2.1GHz, also with a 3MB L2 Cache, also running at 35W. Between the smaller architecture, higher FSB, and 600Mhz speed increase, at just over $200 it could be worth the money to you.

I'm personally not in a hurry to upgrade, for various reasons. Using XP, the dual core 1.5GHz runs fine for me. I've also been watching the prices drop and speeds increase on Socket-P cpu's. I will eventually upgrade, but why rush? The longer I wait, the cheaper (and faster) a cpu I can get for my money.

The cpu can be swapped out through the bottom 'hatch' without a ton of difficulty. I can't give step-by-step instructions as I haven't done this, but I don't see any huge hurdles to overcome. I would just make sure you have a thin coating of Arctic Silver (or something equivelent) to replace any old thermal paste / pad residue. Enthusiasts sometimes actually redo this themselves simply to improve heat dissipation on their stock cpu's.

Step 4: CPU (software)

Picture of CPU (software)

That's right- software for your cpu.

The stock T5250 cpu has another nifty, little-known characteristic. If we take advantage of it, we can make our laptops run cooler and gain battery life! This cpu was used in a lot of notebooks, being one of the most 'budget' cpu's for the Socket-P design.

Old-school overclockers will understand over-volting. Basically, you're running a cpu on more voltage that it is designed for. This increases heat, uses more power, and shortens the life of the chip. Why do it? To get things running faster- to burn the candle on both ends, so to speak. It's a combination of getting the most for your money, and a plain geek-rep do-it-for-the-sake-of-doing-it challenge. It's almost never a wise idea for laptops... or your warranty.

The opposite concept is under-volting. The idea is that all cpu's do not require the full manufacture voltage to run. Lowering the voltage creates less heat, uses less power, and (if anything) extends the life of the chip! What's the down side? On most cpu's, if you lower the voltage too much it will cause instability (read, BSOD).

But here's where our little "budget" chipset really shines.

Using Right Mark CPU Clock Utility, you can lower the voltage as far down as it will go. Instead of a deafult 1.25v, our T5250 cpu can be run at a mere 0.95v! Doing so decreased my cpu temps by more than 10C, and increased my battery life by 15-20 minutes. Get the walkthrough on the changes here; for any other cpu, follow the instructions exactly. Only the T5250 has been proven to usually be 100% stable at the lowest voltage settings. Just to be safe, I have mine set as shown in the picture (slightly higher per each multi), though I ran for a solid week at the minimum voltage with no problems. If you notice any instability under high load, simply bump the higher multipliers up a notch or two.

Step 5: Misc. Tweaks

Picture of Misc. Tweaks

These are a collection of tweaks I learned over the past few months using this laptop. Most of them should be applicable to other makes / models.

Tweaking the video:

The X3100 Intel video is hardly for gaming. However, there's a few things you can do. First off, it is advertised as having "Up to 252MB" of shared graphics memory under Vista. Installing XP, it becomes 384MB! Not a bad upgrade (either the increased video memory or the faster OS) ;)

To get a little more of an edge, download and install the latest driver from Intel. Open Graphics Properties. Under Display Settings, hit Power Settings. Here you can improve things (slightly) by being more energy-wasteful. Under 3D settings, you can also change the "Driver Memory Footprint" to High, which supposedly may help.

Tweaking the performance:

I've already written an XP tweak-guide, so I'll keep this short. Get rid of all those background / startup applications, defragment your drive overnight every few weeks, uninstall / delete things you'll never use, Turn off System Restore unless you actually use it, and turn off Automatic Updates! If you have 14 taskbar icons next to your clock, it takes five minutes to boot up, and you keep getting "low disk space" warnings, you don't need new hardware. You need an hour of easy software maintenance.

Tweaking the battery:

A while back I forgot the charger for my laptop when I left for work. Bugger, I thought, I can get an hour, maybe a little more out of this battery! What on earth will I do for the next 3+ hours till I can run home on lunch?

Everyone's usage will differ, but here's how I stayed chatting and surfing online for three hours, just using the ~6 month old stock battery.

First, I used the under-voltage trick. Remember, less voltage, less heat, less power consumed.

Secondly, I have Windows Power Options set to Max Battery. Not only does this keep standard hardware use to a minimum, but it runs the T5250 cpu at 997Mhz instead of 1.5Ghz while unplugged. If you're websurfing or typing, 2/3 of the CPU is plenty.

Thirdly, I used XP's Hardware Profiles to create a super-battery-extending profile. The how-to from Microsoft is here for setting up Profiles. I created a new one, rebooted, and entered it. Setting the timer at 5 or 10 seconds instead of the default 30 might keep you from gnashing your teeth in impatience during startup. Now the fun begins...

We open the device manager and start disabling anything we can live without for the next three hours. DVD drive? Not needed. PC Card slot? SD card? Firewire? Webcam? Disable them all. Since I'm on Ethernet and have the volume muted, I disabled Wifi and the audio card as well.

I then turned the brightness down as far as it would go, and closed every application but the Firefox tabs I was using. Turning off the auto-hibernate at 3%, I managed to chat on Meebo for three hours and seventeen minutes- at which point I ran home on lunch and grabbed my charger. I keep the Uber-battery profile just in case this happens again, or I need to finish / retrieve some work with the last trickles of power.

Step 6: Final Thoughts

Picture of Final Thoughts

This laptop turned out to be a smart purchase. It has future upgrade-ability, has held up well the past half a year, and is pretty easy to work on. As I previously stated, the Intel X3100 graphics are the weak point here, but for the light- or non-gamer like me, it's sufficient. My screensavers look good anyway! ;)

What's next for my Acer? I'll likely add in the Bluetooth module I built and call it good for another six months. I've kept myself busy with other projects, including building my NES PC, and installing / dual booting OS X Leopard, which runs surprisingly well on this 'budget' machine...

... but that's another Instructable ;)

Splinter Sensei (author)2016-03-15

I was considering to replace Intel Celeron 530 1,73Ghz with Intel Core 2 Duo T9300 or Intel Core 2 Duo T9500 (difference between those 2 CPU's is that the T9500 have 100 MHz more in clock - 2,5Ghz vs 2,6Ghz - specs are all the same for both models (but both of them are awesome CPU's, you won't make a mistake if you choose one of them)). But will update BIOS to v1.35 (without update CPU won't work i assume). Now the thing is will my Acer Extensa 5220 support 800MHz RAM instead of 667 MHz RAM? Also i have switch for Bluetooth but no 4 pin connector found :( It seems Acer Extensa 5220 doesn't have support for Bluetooth module ;-;

Hi there, I just upgraded to T9500 works fine didn't check if 1.35 BIOS has some updates regarding cpu management but my laptop is faster I'll check which RAM module I used let you know cheers

Well i'm in this situation:

Laptop: Acer Extensa
Model: 5220 (not 5620 :3)

Upgraded BIOS to v1.35 (i think before BIOS was v1.16)

Upgraded RAM from 512MB to 1,5GB (i just added one 1GB 667MHz DDR 2 stick)

I have found 2x2GB DDR 2 667MHz sticks and i plan to buy them soon (now i think if you take RAM with speed of 800MHz it will automatically downclock itself to 667MHz because of the motherboard. Also i think 4GB is the max that motherboard can support, however i did saw 2x4GB DDR2 667MHz ram sticks and i have no idea if it's even possible :3)

Found and purchased a Bluetooth Module (tested it and it works like a charm) <3

Replaced WiFi card with Dual Band Card (2,4GHz and 5GHz WiFi Networks) (but without 5GHz antennas (hardware) i won't be able to sniff out 5GHz WiFi's xD)

Replaced Intel Celeron 530 1,73Ghz with Intel Core 2 Duo T9300 (2,5GHz)

Battery is still to be replaced (it barely hold any charge so its on via AC)

Installed OS: Windows 7 Ultimate 64bit (Windows 7 4ever <3)

HDD is stock one. Still same 80GB Hitachi (will consider to replace it with SSD (but those are expensive :3)

Graphics GPU is part of the motherboard itself (so it Dynamically allocates memory from RAM to use it as it's own video memory (i'm kinda ok with that)

I have 358MB (which is max capacity) of "Total Available Graphics Memory"

"Dedicated Video Memory" 0MB. Nuuu i cri T^T - no for gaming :3 (still i just love this lappy because it have so many connectivity options and i just love the unique design)

Actually it can run some good old games :3 (like Moon Base Commander <3)
Or to use PS1 emulator to run good old childhood games <3

Also i used one epic program to update drivers for my lappy. It's called "Snappy Drivers". And it's rly rly awesome plus it's free :D

Le Link:

Love ma lappy <3 1st lappy that i ever got. My dad got it as a gift from his boss. So he gave it to me. It was one of my life dreams to have a laptop. And now i have one <3 I have PC as well, and a tablet (Blueberry NetCat M06) (but it;s touchscreen is broken alongside with the display so :/ i don't bother to even repair it) Phone that i have: Motorola Razr XT910 <3 And that's all from me :3 *Vanishes into the shadows* Cheers (i might say Cheese, because i <3 cheese xD) Oh God, made an long comment boring one too :3 I do apologize.

Hi Splinter,

Sorry about the delay and the RAM speed can't g above 667MHZ

I have bios v1.35
still looking(too lazy to search summer time) for a mini 4 pin connector
Regarding Wi-Fi may be possible to add a 5ghz internal antenna, for connectivity personally I prefer wired connection :p I didn't bother upgrading the original card

Oh i found the 4 pin connector on motherboard. YUS!!! Oh and will use 667 MHz RAM Modules (silly me, i didn't saw the comment about ram speed) (2x2GB). Well i can't find Intel Core 2 Duo T9500 but i found T9300. HDD is 80GB Hitachi - idk but maybe it's possible to replace it with SSD Hard Drive. But for now i'm laying low -huhue *evil laugh of a mad scientist butchering his laptop*

My Acer Extensa 2508, Model No: MS2394 won't let me connect to the internet due to a device/system update, I have looked to update my laptop but can't ssem to come accros a solution.

I'm a student in my seccond year of college and really need to complete my college assighments, this happens every two months or more and is very fustrating. Sometimes my laptop won't let me log on because of an update.

Is there anything I can do without gettting an IT technition to come and fix it as he has already been sereal times to fix it on previous updates.

Hope you can help.

Kind reguards, Amy.

I want to install Windows 7 on my Acer 5620, from windows XP. Before I do the upgrade I wanted to upgrade the memory. I have bought two 2gig memory modules, to upgrade from two 1gig modules. Upon startup the message 'Starting Windows' appears, with the scroll bar, then a blank screen, followed by a restart. Inserting one 2gig module and the machine starts up. Install both and it doesn't. I reinstalled the two 1gig modules and everything is fine. Please help!!!!!!

aabhilash (author)2012-01-25

hi,is it possible upgrade it to 3.0GHz processing speed sir??????

cisguy (author)2012-01-14

I have an Acer 5620 with the power connector pushed in. I took all the visible screws out, but it wont come apart near the screen which is where the power port that is pushed in is. I looked for a guide on taking it completely apart and didn't find one. I've worked on computers for years, but not normally laptops. If you have any advice on this you can email me at Thanks for your help.

kknight2 (author)2011-06-05

I upgraded the laptop from vistato windows 7 and the onboard mic doesn't work, the drivers installed correctly, but the mic just isnt working. when i check the volume settings, the mic seems to be maxed out even though there is no input.
I googled some other sites and others have ben having problems with tis as well. Do yo have any solutions?

abraxas2 (author)kknight22011-10-20

I'm having same problem. Did you ever find a fix ? Anyone ???? I've checked the usual suspects....mute...levels...reinstall driver (at least i think i reinstalled but *&^%$% Microsoft gave the driver an ambiguous "Sound Device" name to suspect driver which could be anything. I presume to be the mic driver).

CharredPC (author)kknight22011-06-17

I'll check what driver version I am using next time I'm at home with the laptop (I, too have upgraded to Windows 7) and verify the mic is working.

rsrcomputer (author)CharredPC2011-07-12

I too have upgraded from Vista to XP to Windows 7.

Mic works.

BUT the battery went completely downhill. Used to be over 2 hours in XP and within week of installing W7 the battery went to 15 minutes.

Any fix, possible to update battery driver??


d9123 (author)2009-12-04

I have a acer extensa 5620-6830 with  a 1.5 CPU. If I change the CPU to T8300 will I have to change the bios?

CharredPC (author)d91232009-12-22

Probably, yes. But flashing the BIOS is not very difficult.

rcoover (author)CharredPC2011-09-05

I am using BIOS version 1.35 which works well with the T8300

rcoover (author)2011-09-05

I've upgraded my T5250 CPU to a T8300. The new chip has an FSB of 800. Checking my memory chips, I find a 2 GB DDR2 chip with a speed of 400 and another 2 GB DDR2 with a speed of 333.

The two mismatched chips seem to work well with each other, but would I have an increase in speed if I replaced the slower chip with a faster one?

wizzy617 (author)2010-02-15

can my 5620 run windows 7

CharredPC (author)wizzy6172010-02-15

Yes! Very well, in fact. These days I no longer use XP at all, but dual boot between Windows 7 and Mac OSX.

kknight2 (author)CharredPC2011-07-14

Hey i wanna run Mac on my 5620 as well, i have iatkos S3 v2, that i run on another system. What version of Mac do you run on your system?

paulvick2002 (author)CharredPC2010-03-15

Hi Charred, I have the same Acer and now my HD makes noise when it spins. Does that mean it's about to break? I am guessing the answer is yes.

CharredPC (author)paulvick20022010-04-04

Yeah, noises when spinning is an internal hard drive problem. The good news is that they're fairly cheap now- if you hunt around, you can get a 500GB replacement for under $100.

wizzy617 (author)wizzy6172010-03-04

and how would i go about doing that

davison112 (author)2009-08-01

I have this same exact laptop, and ws thiking, does yours overheat ALL THE TIME?!?!?!? and was wondering if it does, did you fix it and how?

CharredPC (author)davison1122009-10-29

Mine never overheats, so I'm betting your cpu fan and / or heatsink is clogged up. Check my latest Instructable to find out how to open up the laptop, then try cleaning out any crud you find. You might also try carefully cleaning off the cpu, and re-applying a think layer of fresh thermal paste or Arctic Silver.

Also, it may sound funny, but upgrading the cpu is a big help. The original has a 65nm core, which puts out quite a bit more heat than the newer 45nm design. My temps have gone down since installing a 2.6Ghz T9500!

hjoab (author)CharredPC2011-03-22

Did you need to upgrade the BIOS? where do get the bios upgrade in this case?

abraxas2 (author)2010-10-04

Can you tell me where I might buy these memory modules ? Any specsI need to watch out for on the modules ? Also, I'd like to back my HD up. I do so with a RW DVD and the backup utility. Problem is this, after it finishes with 1 DVD, I am prompted to insert another one whereupon nothing happens after I close the tray. Any ideas ?

paulvick2002 (author)2010-03-15

I installed Rightmark and my temperature dropped by 25 degrees. Thank you!
Also I am thinking about putting Windows 7 on my Acer 5620 as I can for free, do you recommend doing so?

CharredPC (author)paulvick20022010-04-04

Windows 7 runs quite well on my 5620- if you can install it for free, by all means, do so.

loadsasy (author)2010-03-03

i have 1 quest pls help..... Intel Core 2 Duo Mobile 2,26 GHz P8400 works on acer extensa 5620?

CharredPC (author)loadsasy2010-04-04

Probably way too late to help you, but for posterity:

The P8400 will not work in our 5620's, or any GM965 chipset for that matter. Our maximum FSB speed is 800Mhz; the P8400 uses a 1066Mhz FSB.

The DC-in jack on my 2 year-old 5620-6830 has failed.  I know it's the jack, because I bought a new AC adapter and it still doesn't work.  Question - Is it likely to be the jack itself, or something worse (the motherboard).  Can I replace the jack or is it integrated into the m-board?  I tried cracking the case, but couldn't get one edge to come up and I didn't want to force it, so I don't know how it's set up.  Assuming the jack can be pulled off and replaced, I don't know how to do it or even if I can get a replacement jack - will have to contact Acer I suppose for the jack.   Anyway, if anyone has some guidance it will be greatly appreciated. 
By the way, when I bought this the first thing I did was take it to my local geek shop and to have Vista removed.  They installed XP and it's run perfectly ever since.

kenwg (author)kenwg2010-01-13

Good news - I just did a search online for the jack and found lots of them available on line.  Apparently it just plugs into the motherboard.  So I bought one and it's on the way - now I just need to know how to open the case without breaking it....


CharredPC (author)kenwg2010-01-16

Yes, the DC jack is meant to be replaceable. You do have to disassemble the entire laptop, but then it's as simple as unplugging the bad on and plugging in the new one. If you can track down the 5620 service manual, it described how to take everything apart.

kenwg (author)CharredPC2010-02-14

Thanks.  I'll look for the service manual.

zihuajc (author)2010-01-06

hi i have extesna 5620-6830 and i want windows xp but i cant install it somebody can help me 

kenwg (author)zihuajc2010-01-13

As I understand it from the guy who installed XP on mine, XP can't be installed on a computer built for Vista without an additional driver that isn't included on the XP installation disk.  You have to obtain the driver (I don't know where, but it's probably on the Microsoft website), burn a new XP install disk with the extra driver included, and then use that disk as your install disk.  Mine has worked perfectly now for 2 years so I know it can be done.  Good luck.

CharredPC (author)kenwg2010-01-16

You can install XP on most modern laptops, as long as you go into the bios and change the hard drive from AHCI/SATA mode to IDE. Otherwise, yes, you would need a driver that isn't on the XP disc.

ericsotelo (author)2009-03-18

Hey CharredPC, Do you do repair work over the mail? I have this laptop. Acer Extensa 5620 on Vista Home Premium SP1, Intel Core 2 Duo T5550 1.83 GHz 3Gig Mem. No one will downgrade my Laptop to XP Pro for fear that the drivers will not be compatible. What do you charge to do this to my laptop? Thanks, Eric Sotelo P.S. How does Leopard run on the Extensa? Can you do that to my laptop too? LOL.. .Thanks. I would rather just pay someone like you who knows how to do this the right way then me screw up my laptop.. Thanks for responding.

WendyW (author)2008-12-20

I have a question about my laptop Acer Extensa 5620-6830 .Need to know where to purchase a AC/DC adapter so I can use it in the truck as I don't have wireless service yet. Acer stated they didn not make any for this computer but is there a universal one that will work?

red-king (author)WendyW2009-02-25

I found it... unfortunately its quite large...

red-king (author)WendyW2009-02-25

I think there is one. i'll post another reply once i find it.

masterpj (author)2008-12-05

well i improved my laptop with ensane result myself. i am laptop expert (no joke) i dont have tutorials, because i either dont have time or well it's not always easy to explain.

Khalili (author)2008-09-22

Can I upgrade my graphics (Current: X3100) with some external graphic card. Regards.

CharredPC (author)Khalili2008-09-22

Unfortunately not. This laptop has no way to upgrade the videocard.

red-king (author)CharredPC2008-10-24

someone told me that it will support a Nvidia 8600 Mobility GT GPU. can anyone tell me if this is correct or not?

CharredPC (author)red-king2008-10-29

As I said, unfortunately there is no physical way to upgrade the video card in this laptop. There simply isn't a slot to be able to do it.

devahoch (author)2008-10-03

Hi there! I have a Extensa 5220 with Celeron M 540 ( 1.73 GHz), without Bluetooth and without Webcamera . I want to upgrade with some duo core processor about T-5500, it's possible do that ???, Motherboard is support for duo core???? I want to include Bluetooth to internal NB too, But i don't know open the cover and keyboard, it's here some instruction for open cover of Extensa series??? I was include the internal Webcamera from Aspire 3100 to This Extensa NB, it works very good, I have this camera when I buyed the display from Aspire 3100.

techwalker (author)2008-09-22

I really enjoyed your Instructable, I guess if you upgrade the processor you would need to update the bios possibly. I put a 7200RPM hard drive in my Dell Laptop and I think the difference in performance was quite noticeable, with only a minor hit in battery life.
