- Problem with a laptop which hungs up

I have just bought an old IBM ThinkPad A20m.
There is a problem with this laptop - it hangs up during
installation of Windows XP or Fedora Core (sometimes when
Fedora's installer initializes from DVD). There is no special
moment, when it hungs up - sometimes during files copying, sometimes
during installation (in different moments) both in Win XP, Fedora and Red
Sometimes the power turns off during installation
- especially after I press a button (e.g. "F8"
for accepting license agrement or "F" for formating a partition in Win XP
Sometimes, when I boot from Win95 diskette, it hangs or shows "Overflow
during division by zero" several times and then hangs up.
I run memtest86 to see if the memory is correct - and it is correct (the
didn't report any errors).
The person I bought the laptop from has said, it is possible that CMOS
I checked the battery. Without load it has 2.84 V, and with 500 kOhm
also has 2.84 V. ThinkPad's manual says that correct voltage of backup
battery is from
2.5 V to 3.2 V.
What could be the reason, the laptop hangs up?
Thanks in advance for answers.
Re: Problem with a laptop which hungs up
Shouldnt produce that particular symptom.
Can be a lot of things, everything from a dry joint or
cracked trace to a bad connection to the power supply etc.
Does it ever do that when just sitting at say the
setup screen after having booted the XP CD etc ?
Very likely a bad joint or cracked trace etc and the seller knows
damned well its flakey and thats why he was selling it.
