Flashing lightning bolt on Compaq C300
\015 I have Compaq C300. The lightning bolt repeatedly flashes. Is the battery bad or do I have a power connection problem? Background: The household cat ate through the AC power cord. The system ran for a while and would shut down indicating that it was running on a dying battery. I have replaced the power supply and now when I connect it the system fan come on for a perhaps a second and the start up lights flash orange then the system shuts down and the the lightning bold flashes orange. When I press the power button the system seem to want to start up and the light on the power button flashes organge for a few seconds and then shut off leaving only the lightning bolt flashing. Is this a power supply problem or a battery problem?\015
This sounds like a battery problem. The best way to test this is to remove the battery and then power the laptop up with just the power cord plugged in but no battery. If the computer boots then the battery is bad you will need a replacement. Also try letting the battery charge for a day. Be sure that the charging light is coming on when you have it plugged in.
I think the battery is depleted so the power supply can no longer charge the battery
