Introduction: How to Use OLD LAPTOP
This Instructable is dedicated to my old laptop
HP Pvallion Dv6
In this Project I'l tell about the possible uses of our Old Laptop
I'f you have any queries or suggestions comment below :)
Also tell me if you have any further ideas.
Step 1: Materials Needed
Some Pieces of paper
Laptop (the most Important)
Step 2: Listing of Parts Obtained
The parts are as follows-
1) LCD Screen
2) Graphic card (Cooling fan)
4) DVD player
5) Mother board
7) Internal Hard disk
8) Ports(USB and HDMI)
Step 3: Use of LCD Screen
Once the screen is been removed carefully
Turn is backwards and see the serial number give on it's back and check it.
To convert you can covert the BARE LCD into A USEFUL one by using a LCD/LED contoller board.
you can buy one from here.
Step 4: Use of Graphic Controller
The graphic controller of any laptop is a valuable item and it can be sold in second hand item.
The removal of the GPU should be done carefully such that it does not get damaged. The cooling Fan should be removed.
The use of the cooling fan would be covered in other instructables.
Step 5: Internal DVD Player
Now the most important part of any laptop is Writable disk player.
This player can be sold seprately on Ebay or any other site.
Step 6: Motherboard
The Motherboard consists of many important parts that can used-
It can be either sold seperatly or it can be used in another Laptop or PC with an empty slot.
2) Power connectors
for more information on power connector click here
3) SATA slots
The would help you to support your hardisk by connecting it to your motherboard.Old sata slot can be used to replace not working slots(sata)
4) BIOS chip (least likely to be sold)
If your old computer has same O.S as your new one than BIOS chip can be used in the new one laptop
5) North and South bridge
The south bridge chipset can be sold individually.
6) Front Panel Connectors
7) USB Headers and Audio Header
The are the connectors that connect to extrenal pendrives or hardisks or audio ports
8) Rear Connectors
Step 7: Hard Disk
Hard disk from an old laptop is the most valuable and easily usable part. The hard disk that I obtained was a Seagate 320GB 7200 rpm one. I had got it converted into a external hard disk by buying a SATA Casing.
Step 8: The Battery
Identify the weak spot somewhere along the seams, and pry until the pack pops open.I carefully insert a screwdriver blade and twist to separate. Some packs pop right open, some take a little more effort. Because the packs are usually ultrasonic welded along the seams, with added double sided tape.
If having trouble finding a weak spot along the seams, use a dremel saw or cutting disk to cut through an angle - not along the seams, or you risk damaging cells. Be careful during doing this process.
Now,pull the cell assembly out from the battery
Then,carefully cut the tabs/ wires that are connected to the charging circuit and between the cells using a pair of scissor.After separating the chairing board I kept it for future projects.
I found 6 Li Ion batteries manufactured by HP .The capacity was 4200 mAh. The two batteries are wired in parallel, and 3 parallel packs are connected in series for the desired voltage and mAh.
Twist the solder tabs off by using a nose pliers.If you want to build a pack with the cells, you might want to keep the tabs instead of twisting them off, as it makes soldering a lot easier and safer. After the tabs are pulled off, gently dremel the weld points until the surface is flat.
1) measure the the voltage in individual cells if the voltage is below 2.5 v, then throw them away.
2) Now charge the remaning cells and if they get hot hot just throw them away
now You can use the remaning cells to power any thing and also to make a power bank.
Step 9: Last Battery Charger
You can sell the battery charger for a good prize online
or you can use it in your new laptop.
