T43 hanging and jerky

[PriitM]

Hi!

I got T43 2668 with 1.86ghz CPU and 2GB RAM.

T43 started doing constant beeps(you know, the system busy or 3 keys pressed at once), mouse and KB was unresponsive. I had to do hard power off by button. Next boot BIOS screen was on for a while and I got error message 'No operation system found'. Shortly after removing and reinstalling HDD it was able to boot, but mouse cursor and sometimes POST RAM test was jerky(stopped for second-few) and continued.

PC Doctor found no errors, fujitsu hard drive diagnostics utility found no errors.
I tried other keyboard and touchpad-palmrest, reinstalled heatsink, removed CMOS battery for a while, tried running the computer without WiFi card.
It is not windows issue either, I tried reinstalling, but the system hangs just too much.

Thinkpad has had USB port over current error message for a few months, but I barely used them anyways and kept 'em disabled.

Sometimes it works perfectly for few moments and then it starts to mess around again.
Any ideas?

Welcome to the forum!

Your T43 has a failing Southbridge chip which is a common problem on these machines.

The chip can be re-balled, or the motherboard replaced entirely.

Good luck.
