I usually find that it will charge when the machine is turned off. But no story here as to the age of the battery. It is proper for this to happen after a few years. But not a word about age or if the charger is not the one that the laptop came with. Sometimes I encounter the owner has used a non Dell charger or the power plug on the laptop is loose.
Anyhow, the BIOS should not fix the usual causes.
i've got a problem when updating BIOS Via SupportAssist, when i clicked "install selected" then it stuck in queued..
help, i've got a battery problem it says"plugged in, charging" but it's not gainning.. i've search on the internet that i should update the BIOS.. thankyou..
