I just recently acquired a 600X, and will be using it as a back-up notebook primarily for traveling. I think it's going to meet my needs well, and keep my other new notebook home, and out of harms way on commercial flights.

The Li-Ion battery is completely dead - not suprised. The IBM FRU P/N is 10L2158 and is 10.8V @3200ma. I've noted several reasonable deals on batteries for the 600X on eBay for around $35.00. These batteries are typically rated at 3800ma to 4000ma.

Hence my question: Is the 600X built-in charging circuit up to the task with these replacement Li-Ion packs rated 600ma to 800ma higher than the standard battery pack? I would assume it is a current-limited slow (trickle) charger, but I just wanted to make sure I don't fry the battery charging circuit by installing a higher capacity battery.

And, one other question, what is the best solution to clean the display panel? Just plain old water with a bit of soap, and a soft cotton cloth? Or, is there a better cleaner available. There appears to be some grease spots on the panel, thus the question.

Thanks.

The battery part number you should be using is 12J2464, which is the marketing part number, not the FRU. You'll find more hits with that one.

I would not buy a battery from eBay unless they said it was new. New batteries have a wide range of prices, and Lenovo is selling IBM batteries for the 600 for $85 right now. It's an excellent price.

Your power supply will charge the higher capacity cells just fine. It will just take a little longer.

Go to the ThinkPad support site and download your user guide. A damp soft cloth is recommended for the display, and a tiny bit of soap won't hurt it.
