battery light flashing, red cross on battery symbol, 0% remaining even with AC source
12-28-2016 01:48 PM
HP laptop 6830s, windows XP
1) I had my laptop on standby and forgot to connect to the power source overnight.
Next day I noticed the amber battery light flashing (checked the manual which said its because the battery reached a critically low level).
I have turned on the laptop whilst on the AC source and is working fine. When I click on the icon it says:
current power source= ACpower
total battery remaining: 0%
below this there is an icon of a battery with a red cross - when I click on that icon I get another window and it says power state is on line.
Any suggestions?
2) If this is an indication that the battery needs replacing, can I keep using the laptop with the AC source??
