My laptop's CMOS battery is acting up – not charging properly. It goes through a boot loop 4-5 times before finally starting. I've tried switching the battery twice now, using ML1220 (the same type that came with the laptop). Weird thing is, the new batteries work fine on the first day, but the next day, they're totally dead.
Just to let you know, I've already updated all firmware to the latest versions, but the issue persists.
Do I keep throwing in new batteries until something sticks, or is there a better fix for this?
