Re: W520 requires 170W AC adapter

"what exactly is does number 43X6713 refer to?"

It is does refers to the much longer PART'S SERIAL NUMBER that you found it in.

Really? You've never seen a SERIAL NUMBER or production code on a part before?

Re: T61 falling apart - what now ?

Actually...I've got a spare T61P, I bought it off-lease last year so I could just swap drives and keep using my installation, while figuring out how to fix my own 5 year old T61P. Since that's both fixed and replaced...I've got a really clean T61P with licensed XP installation on it. If anyone wants...

joester, you said "I don't believe there data stored in the battery." and I responded to that. Whether power is needed to maintain the data is a different issue, but static memory (flash, eeprom, whatever) is so cheap that's a non-issue. Either way the logic can be set to "never use this device agai...

Re: Reviving Thinkpad batteries

The power manager software does read some data that is stored in the battery pack. If you unintuitively scroll the screen down "below the fold" you will find the power manager knows each battery pack by serial number, maker, and other information that is stored in the pack. I have no idea what else ...

This is part of the mystery of lithium battery controllers. The controller will normally cut off power form the pack if the combined voltage from the pack falls below a certain point, to prevent cell damage. It could well be that if the controller sees any one cell drop below the minimum cell voltag...

I'm using a W530 running Win7/64 and no matter how often I tell the color calibrator to nag me just once a month, it nags me every week. It just can't seem to count to FOUR weeks between nags. Has anyone else had this problem or found a fix for it?

The 6459 is 07/12, 2GHz CPU.
The 6458 is 08/05, 2.6GHz CPU.

So if the 6459 (not accesible right now) shows a 7xxx series CPU, it would need a BIOS update. Yes?
