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?

Re: Flashing lightning bolt on Compaq C300
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.

There seems to be a problem with charging your battery. Please remove the battery, connect the power adapter and turn on your PC. If it works, test with battery alone. If possible, check your battery in a simliar laptop to make sure if there's a problem in the battery.
We had the same problem. I figured out it was NOT the main battery, but the auxilary battery. The batter life WITH the auxiliary was 68% total, when I removed the 2nd battery the battery life shot back up to 98% AND the flashing orange / red lights were gone (both on the power source and off). I then replaced the auxiliary battery with a spar back up to make SURE that it was not a fluke and with the new backup battery firmly in place the lights still did not flash. Problem solved.
It sounds to me like there's a short in the AC adapters causing it to have enough power to charge the unit when it's not pulling power, but once it starts pulling power, it basically becomes overwhelmed and can't do both power and charge. There's also the chance that the DC jack [which the AC adapter plugs into] is bad. However I'd suggest checking the adapter first because it's simple to obtain a new one and if it doesn't work, you can most likely just return it and say it doesn't work as opposed to a dc jack being repaired which would have to be done by a professional with the skills to handle it [of course unless it's under warrenty, less than a year old, but judging by the model I'd say it's probably not]
Ok the lightning bolt is your power indicator: solid green-charging, Flashing green-fully charged, flashing red-low battery, flashing red three times the once green-bad battery. the "trash can" looking one is your hard drive activity indicator it will flash while your hard drive is reading and writing.
