I have never opened this model but this may help. Try opening the top by
removing the button strip, then the keyboard. You may find additional
screws that anchor the parts to the bottom. You also may find that once the
keyboard is removed, the battery will be looking right at you. Some, but
not all, laptop designs make changing the battery easy. Most assume that
you'll take it to a tech for service anyway. It's worth a try. HTH, J

Page 2-38 will tell you what to do, BUT unless you are
experienced in servicing laptops I would caution you not to
do it. It's mind bendingly complex in this model. It's
unbelieveable, you have to remove the motherboard to get to it.

After working on ThinkPads for the last couple of years I've been seriously
spoilt. I can change most ThinkPad's CPU in a few minutes, half an hour at
most.

The other day I decided to upgrade the CPU in an older Compaq laptop I have
that I don't really know what to do with. It doesn't have wifi and the
battery's dead so it's not worth much to sell, in fact I'd get more for the
parts than the laptop. I hate that. How can a working, reliable laptop with
a genuine Win XP Pro COA not be worth more than the sum of half of it's
parts? Crazy.

It had a Celeron M 1.3GHz with 512KB of L2 cache, I fitted a Dothan 1.8GHz
with 2MB of cache. It flies now *and* runs cooler as the Celeron didn't have
speed-step and ran at 1.3GHz all the time. The Dothan drops to 600MHz and a
really low vcore when it's not under load and even at it's full speed of
1.8GHz has a lower vcore than the old Celeron and produces less heat. LOL,
not that it needs the extra power as I'm currently only using it as a music
player with some decent 2.1 speakers plugged into it. However less heat is
good.

Anyway, I had to remove the bloody *screen* to get to the CPU (not to
mention a whole bunch of other bits incuding the complete top of the
case...). Give me ThinkPads any day.
