Help regarding 2 T43s

[dcai777]

After my T43's keyboard died I got a friend's very good condition T43 2687-D3U, which is almost identical to my 2687-D8U. My T43 is in rather bad condition, so I took the HDD and cooler out of my T43 and transplanted them into my friends, since his only had a 40GB hard drive and his cooler was noisy. I also added a 1GB dimm into the keyboard slot and a 512MB dimm into the bottom slot. After booting up, I reinstalled Windows. After installing all the drivers, it will consistently freeze. The friend's T43 was quite dusty, although I had cleaned it so I put all the parts back in my own T43 (suspecting there might have been dust in the dimm slots). The same freezing issue still happens, even with mine although now after freezing it beeps 5 times every few seconds. Could it be the hard drive (a 320GB WD Blue)?

Do you mean freezing where you have to restart the computer or lagging/stuttering/hanging but recovering without requiring a restart of your T43?

[dcai777]

I mean freezing and requiring a restart, however it seems like its only the arrow pointer (installs that were going on before continue and I can see that, web pages continue loading)

Remove the battery and run the machine on AC only. Any difference in behaviour?

[dcai777]

Am testing it now, thanks!

Great solution. Thank you.

Thanks for the advice, I've been running it like this for a while and it works fine (battery only works for ~10 mins of runtime anyway).

Any idea as to why it freezes with the battery in though?

My guess is that there's something wrong with the battery itself, but unless you have another one to test the system with no one can say for sure.

The friend's T43 had a dead 9-cell (blinking yellow light), but my original never had any problems as said before. I'll just run it without the battery for now, thanks for the advice!

There are power saving features on the T43 that are better left turned off. The throttling of the CPU and power saving features in the wifi card deteriorate performance when on battery power using Win XP. My guess by removing the battery means that your T43 has incorrect performance settings in either the bios or OS or perhaps both. By removing the battery you are relying solely on AC/DC power and not the battery settings of the T43.

I always use the T43 plugged in, so wouldn't there be no difference?

A bad battery will send a scrambled signal - for a lack of proper term - and freeze the machine. It's one of the notorious "features" of the *60/61 range, but T4x units are not immune from it either.

You should really borrow a *known good* battery and verify how the system behaves with it. Everything else is a guessing game to one extent or another.

[Hans Gruber]

That is really good advice. If with a known good battery (one that holds a charge) has the same problem or no problem. You would have a solution to the anomaly you are experiencing on your T43.
