My wife recently bought me an Acer Extensa 5620 for Christmas. It's a great little unit with a lot of potential, but the one big flaw was the operating system: it came with Windows Vista. The fast hardware was crippled by the bloated, clumsy OS. I was therefore forced to figure out exactly how to get XP on it, so wrote up a guide to help others. It should apply to different Acer notebooks, and likely has info useful to other brands as well.

It's not as simple at it used to be. Today's laptops are 'meant' for Vista, so trying to install XP often isn't easy. In the case of my 5620, the hard drive wasn't even detected until I researched and changed Bios settings (known as the AHCI issue). I'm SO much happier after ditching Vista, though- when I first got it, a 1GHz Pentium III with XP could have run circles around it!

Step 1: Preparation

Don't immediately wipe Vista! It's actually useful for another hour or so. Use Acer's backup software (mine had an Acer floating toolbar with this) to do two things-

First, a Full Backup of your system. Trust me, if you ever have to send your Acer in for servicing, it better have Vista on it or your warranty could be voided. Plus, someday when you sell it, uninformed people think it's a plus point ;)

Secondly, why bother downloading random drivers you hope are the right ones? Acer makes it easy with its Driver and Application backup CD creator. A little known fact is that these drivers appear to be both the complete Vista AND XP set. Once you're done, you'll have burned three DVD's, and be ready for some XP goodness! If you've already wiped it, or just want the latest available, grab them from [ftp://ftp.support.acer-euro.com/notebook/ here]. I did both, just in case, throwing the newest onto a 256MB USB drive. Thirdly, look in Device Manager to see what AHCI Disk Controller you have! Write this down. On the Best Buy Acer Extensa 5620-6830, it's the 'Intel 82801HEM/HBM SATA AHCI.' Other models may be slightly different. This info is important later, and it can be difficult to find out without some annoying trial and error.

Ah, this is a really old article(?), so perhaps it doesn't matter now. <br> <br>I've got an Acer Extensa 5420, and I found out the hard way, by simply cloning to a larger hard drive, that it's very easy to break access to the PQSERVICE partition to restore my laptop to factory default settings. Obviously changes or corrupting the C: or PQSERVICE partition will break access via Alt+F10 or eRcovery, but so can hiding or reformatting the D: DATA partition, since eRecovery establishes a &quot;relationship&quot; with D: during initial setup, which it seems can only be modified manually afterward, perhaps requiring both the registry and BCDEdit. It's possible to suggest that I'm wrong, but I've spent many, many days using the original hard drive and two cloned drives trying to determine why the clones lose access to the recovery partition. <br> <br>Also, I did indeed make recovery DVD's using eRecovery, and tried to restore access to PQSERVICE by using them, but they failed every time. The DVD's restored the C: partition, but not access to the recovery partition. Considering the recovery partition utilizes a &quot;switch&quot; or &quot;input code&quot; (Alt+F10) for access, and the partition is hidden using the partition ID=27, it's possible that eRecovery discs will not include the recovery partition. So far cloning using the 2009 Seagate or WD version of Acronis True Image both somehow managed to break access to the recovery partition. EaseUS ToDo Backup Free also failed to restore after performing file or sector by sector backups, but that was because it somehow misinterpreted the allocated space of all the partitions to slightly larger than the factory hard drive. The problem might be the utility Acer used to create the partitions, how they were accessed at the time, and/or the BIOS in conjunction with the physical specifications. EaseUS Drive Clone/Copy cannot technically clone from large to small hard drives, and it has an &quot;unwritten&quot; strict technical methodology which must be followed, but it better revealed the problem with restoration. If you decrease the size of partition D: DATA, you can clone from large to small, or create backups which will be more successful at restoring. This suggests that slightly &quot;shrinking&quot; volume D: DATA, before using a third-party drive imaging/backup solution will significantly improve chances for successful recovery later. In both Vista, Windows 7, and it would seem Windows 8, you can expand volume D: DATA after a successful restore using disk management. <br> <br>All of this is simply to suggest that while eRecovery should restore volume C: ACER, it won't necessarily restore PQSERVICE or volume D: DATA. In testing I placed files in both volumes C and D, and after restoring using the discs, the files I placed in volume D were still present, and I could not access the &quot;built-in&quot; recovery. So, considering warranty and factory installed hard drive size, it might be better to simply replace the originally installed hard drive with a larger or faster hard drive, keeping the older drive in case of needed factory repair. Otherwise, I recommend that before you &quot;wipe&quot; the hard drive of all partitions, or install any OS which can break Acer's MBR offset for recovery, test your backup discs using a different borrowed or bought hard drive. If the test drive is smaller, but more than half the size of the original, like a 120GB to a 160GB or a 60GB to an 80GB, simply &quot;shrink&quot; volume D: DATA before creating the backup. You won't need to create another set of recovery disks if successful because you can always &quot;expand&quot; volume D: DATA after completing the recovery. <br> <br>Then again, maybe my laptop just doesn't like me and is making my life difficult, which makes my comment a moot point.
I have the the same laptop as the maker of this instructable and i c ant find a working driver for hardware acel for the screen<br>Hope some can help if so email me at powdertoybeta@gmail.com
where can i find this driver and app back up cd creator??
i am having trouble changing the boot order in bios. it is simply that the plus and minus keys do not work to change the boot order. i can however, use the x to disable the hdd while i want the dvd to boot up and then turn it off later. this works but it is not very elegant! perhaps i need to install some keyboard driver?
its easy! f5 bottom f6 top
Did you see my earlier note that it is the F5/F6 keys that are used to change the boot order?
No, i missed it. i managed it anyhow. Many thanks for this whole set up instructable. It has been really helpful. Couldn't have done it without.
using xp embedded can use tap.exe that saves all trouble.I like xp embedded!
Oddly enough, though i know Vista is terrible, mine isn't that bad. Updates go well, and it's much faster than it should be. It may be do to meticulous cleaning of its files, and things. I wish i could get Ubentu or XP, but any big download gives my parents heart attacks.
the next logical update to Windows XP is Ubuntu
VERY useful 'ibble. To me Vista is an OS upgrade, performace downgrade and XP is an OS downgrade, performance upgrade.<br> <br> I've been asked by so many people to replace vista with XP on their laptops its rediculous. For anyone saying Vista is better than XP this is my experience:<br> <br> <strong>Vista...................... </strong><br> 1. Had to reinstall Vista on 19 occasions after automatic updates screwed it up.<br> 2. Took 4 hours and 30mins to backup 80GB to another hardrive.<br> 3. Can't install any software updates for my phone.<br> 4. Slow to boot. around 5mins from boot to desktop.<br> 5. Takes ages to detect and connect to my other 2 XP and 1 Win 2000 PCs on my home network.<br> 6. stupid file search. it can't find files i know exist.<br> <br> <strong>After XP Upgrade............................. </strong><br> 1. Only reinstalled XP once (power failure during update).<br> 2. Took 2 hours 10mins to backup 120GB.<br> 3. Installed all updates on my phone.and even upgraded its OS.<br> 4. boots faster. 2mins from boot to desktop.<br> 5. VERY BIG increase in speed.<br> 6. Connects to my home network and other PCs in seconds<br> 7. More reliable drivers.<br> 8. All my hardware works as it should and not when the OS says so.<br> 9. I can actually find files using Windows Explorer's search bar.<br> <br> So if you want to go vista to xp i highly recommend it.<br> <br> This i just my opinion.
That's pretty much the universal opinion, even Microsoft's- hence, Windows 7 :)
Hi CharredPC... first of all... thank you very much for your upgrade to XP from Vista instructions... very helpful for my extensa 5620.<br><br>I have since &quot;upgraded&quot; to Windows 7 on extensa 5620 but unfortunately ran into the &quot;replace battery&quot; issue so now get 10 minutes on battery vs 2+ hours when used xp.<br><br>Been trying to find solution but all options that I have tried so far [disable acpi, drain battery in bios screen, etc.] have not worked.<br><br>When check under device manager I do have yellow exclamation point for something labelled ACPI. Is there a driver for ACPI for Windows 7 that you used and if yes, from where? Can not find on acer us or euro site.<br><br>Got similar problem on another acer after upgraded to windows 7 but had battery replaced under warranty and switched back to xp.<br><br>Appreciate any help.<br><br>Thanks!!
Shouldn't it be, "How to DOWNGRADE from Vista to Windows XP??"
no. Vista is very slow and full of bugs.
Depends on your hardware, doesn't it? Vista needs at least 2Gig RAM - I UPGRADED my system from XP to Vista - Never looked back - VERY STABLE!
thats probably the case. I've never tried vista myself, all these complaints about it are probably people with barely over 2gig ram.
That in itself is my complaint. There is simply no reason to require over 2 GB of RAM and a CPU made within the last 12 months just to have your system run smoothly. It's ridiculous. Stop the consumer sheep mentality. Think. Look at it this way:<br/><br/> If I told you that when you bought a new car it would have a V8 engine instead a of a four-cylinder, a 25 gallon gas tank instead of 12, twice the amperage from the alternator and upgraded all-season radials... you'd be pleased, right? Okay, now let's say you buy it and have all that, but the new car <em>performs exactly the same as your last one</em>- or <strong>worse</strong>. When you go complain to the dealership, they shrug and say you should've bought the twelve-cylinder model to see any improvement. Does that make sense to you? Because that's the position you're defending here; that's what you're defiantly calling an upgrade.<br/><br/> Both cars in my example get you from point A to point B, just like XP and Vista accomplish the exact same tasks. If you want to nitpick about feature differences- fine. Can't live without the eye candy? <a rel="nofollow" href="http://www.instructables.com/id/WinXP-Overhaul-Guide-How-to-make-it-look-like-Vis/">Another guide</a> I've posted explains how to make XP virtually a clone of Vista. Like the new search feature, 'bread crumb' explorer link, sidebar and widgets? Same guide, all free. Everything runs smooth even on this outdated old work computer I'm on with &quot;only&quot; 1GB of RAM. Look at that, I just saved $500+! This may surprise you, but some people would rather tinker for an hour or so instead of pointlessly dropping half a grand to <em>reduce</em> performance.<br/><br/> Lastly, to each their own. You're as much of a Vista zealot as we are XP advocates. I posted this Acer guide knowing many people think the way I do, and could use some guidance. Some people throw money and hardware at a software problem- other people just solve the software problem, which is what we're doing here. If you love Vista and are happy with it, that's great. Honestly, I'm glad it worked for you. I guess some people can accept driving a new BMW that runs like a Honda Civic. We'll just be over here, turning or new machines into Ferrari's ;)<br/>
obviously you dont play any computer games and don't require a high-power PC.
"don't require a high-power PC" ... much like 90% of the world. And we do play games. Last I checked, a new videocard was cheaper than a whole new computer; not to mention the better frame rates / lower overhead within XP :)
i know people that are still running windows 98 and dont really know theres a new operating system or even what an operating system is, i hate that
If I could I would still use 98 myself. I eventually had to go to xp because of lack of suport for 98. Just when I finally get xp running to my satisfaction, vista appears. Doh! I didnt want xp. I dont want vista. I know eventually I will have to have vista, and when I finaly get a pc fast enough to run it properly, the next windows will come out. I wish linux was actually a viable alternative.
Ditto. 98SE is probably the most stable version of 'doze I have encountered. Unfortunately I cannot find a web browser that copes with all the modern shovel ware of the average website, and so have had to upgrade certain machines to XP. Some form of Linux will be my next choice.
Then just buy more ram.
James, you can't always &quot;just buy more ram&quot;.&nbsp; What is your board is maxed out (yes, there are some boards who have a limit to the amount of ram that can be installed)?&nbsp; <br /> <br /> I have done the same thing as the author has done here (though, I was not as prepared...good job CharredPC!)&nbsp; and everyone I have done this for has enjoyed XP much more than the Vista with which their computers originally came. <br /> <br /> For the haters I say, why are you in here to begin with?&nbsp; If you like Vista, fine.&nbsp; CharredPC is not proselytizing here, just offereing a good Instructable.<br />
Wow...LOL, just realized this was from Jan 08.&nbsp; I think I need my bifocals upgraded.<br />
Brilliant. Another person throwing money and hardware at a software problem.
dude. its not a "problem" its jsut one of the features of vista. if you have a pc with less than 2gig ram, use XP, if you have more, use vista. problem solved. honestly I dont see the point. this is a MATTER OF OPINION. It doesnt matter what either of us think, just use whichever you prefer and i'll use the one I prefer.
You're right, it's just a feature. An undocumented bonus feature, like every MS problem ;) Sounds good, enjoy your Vista.
everybody did the same thing with XP, 98, and 2000, ME just sucked, and hated it and said it was slow, bad and to switch back to better systems before those new ones came out..
Read all the comments, then post, please. This argument has been brought up and dismissed. You're just echoing points that have been disproved/explained.
