Re: [Thinkpad] 770 battery doesn't work

First of all, did you purchase NEW batterys or ebay "specials", because just
about all used 770 batterys are SHOT.
If it really is a NEW battery, change the CMOS/RTC battery on the 770. A
dead CMOS battery will prevent the main battery from being seen properly.
But I still think you bought used batterys, and they are just dead.
