There is no real manual for this, I have done it before though and have typed out the directions here for you, plus a link for the new battery if you need it:
Please make sure you rate my answer 4 thumbs up, it is extremely important to me. I would be forever grateful if you could do so. If you need more help on this question please just respond to my answer here and I will get right back to you.
1) Remove 4 screws under ends of rubber strips on back. (All screws are Torx number 6)
2) Remove back cover. Front frame around screen comes off easier now.
Remove 2 screws in round top circuit board. Remove 4 screws from lower
circuit board. These two boards may have a glue connection. Do not worry
if it separates
4) Lay back circuit boards to unplug battery.
Note flat ribbon cables are fragile. The 3 wire plug is the battery.
Unplug wires to battery from receptacle on circuit board.
Remove front screen by pressing a screwdriver against the small metal
tags that follow the edge of the screen. The tabs need to be pushed in
slightly to allow you to lift the screen out. It may need some leverage,
but be careful not to put the screwdriver to far behind the screen as
there are a couple of thin cables for the connections.
remove the hard drive you may need to unscrew the vertical black tags
about 2 cm long. These simply come away and are grasping the business
card size silver box IE the hard drive. The rubber end caps are pressed
in, pry out with small screw driver.
7) Remove battery and replace.
Note the two sided sticky tape around battery. When putting more tape
on, be careful you do not put to much around the right hand end as it
will connect with the thin cable when you put it all back together.
9) Reverse assembly. Mine works fine now, good luck. (and so does mine! BLP)
I did not have a Torx #6 screwdriver nor could I buy one locally. I
found a #7 mini star bit works just fine. Source: Harbor Freight item #

torx screwdrivers, a very small philips (star), a straight screwdriver
and a plastic pry tool. Whatever I paid more than another place it was
When disassembling do not remove the battery clip.
Just pop out the battery from the front (experienced having to
reassemble that whole thing). Also having a set of tweezers to put the
electrical connections back together helped a bunch.
