Sure, after discharging the battery till 8V i leaved it for a while and after few minutes battery voltage rised up to 11 V. Main issue I reported is not charging battery and laptop does not works on battery. Overall thanks for communication.  ... Afficher plus

No no, I connect the bulb to full battery pack 15,2 V, after disconnecting the bulb battery voltage in 10 minutes rised up to 11 volts. So the cells are ok. I found on youtube some very similar issues fixing videos, where laptops batteries where does not charged, and problem was dead IC voltage controller chip.  ... Afficher plus

I connected directly to battery a load (car halogen bulb, 55 W) and discharged a battery till 8 V. Bulb shined 25 minutes. Then installed battery to laptop and plugged in a charger ant check by multimeter charging voltage on cells - did not found any voltage. Results: the battery is not charging. ... Afficher plus

I disassembled both two new batteries, both have normal voltage 15,2 V, so I guess the problem is on motherboard power controller. Next step is put out the motherboard and looks for problem. Thanks. ... Afficher plus

Have checked by multimeter new batteries voltage on the pins - did not found nothing. No any voltage. On the old one on some pins found 2-3 V.  Perhaps the "new" batteries are dead but I guess the problem is not on batteries only. Will research further. Now I need a really working battery for test.Thanks everybody for comments. ... Afficher plus
