If you’ve got a Lenovo laptop with a battery that’s providing sub-par performance, you just might be
for a free replacement.
The batteries in question don’t present any fire or safety hazard, so there’s no reason to worry about your health – the folks at Lenovo are simply looking to make nice. “Irreparable damage” and “battery cannot be charged” error messages from the Power Manager or Message Center are the main indicators that you have a bad battery.
If you’re not sure, but you have a ThinkPad R60, R61, T60 or T61 with battery FRU part numbers 42T4546, 42T4566 or 92P1141, and/or a model X60 or X61, with battery part numbers 42T4550, 42T4567, 42T4568, 92P1169, 92P1173, 93P5028 or 93P5030, it’s suggested that you should run the Battery Diagnostic Tool ( available here ), to find out if you need to swap it out
