Hello
Pls need help with dell d600 lat the problem is battery not chargin i have replaced new battery also lpc47n254. The laptop comes on with ac adapter and shows battery not present the bat_pres# goes low when i insert the battery. But does not power on with battery.
Thanks

Ну так блок питания родной надо ставить - марка указана на обратной стороне ноута.

АКБ должна определяться независимо от "родности" Б.П. Могу ошибаться, но на D600 в биосе можно было статус АКБ увидеть.

yes it can be seen status in the bios but says battery not present. i have checked the battery pbat_pres# signal get low to micom lpc47n254-aaq i have changed also that.but when we put battery there is a 5voth at power switch but laptop does not come on.the 3.3v and 5v does not come on.
