Please I need help with my new Notebook HP c6910p. I left it in a car trunk under a very cold weather for about 10 hours. The Cold has damaged the LAPTOP because it has refuse to come on for about three days now and the batter light does not come on anymore when plugged. Please how can I repair it? Thanks
Leave it on the charger overnite with lid closed and try it in the morning...What's very cold? Battery's don't like extremes, try turning it on without it.I tried turning it on but the orange light keeps blinking. I don't know what that meansHow soon, after bringing the laptop inside, did you try to turn it on?  Not allowing it time to gradually warm to room temperature before turning it on may have resulted in some condensation of moisture inside the computer.  The presence of moisture when you turned on the computer could have caused electrical damage to components. That may be the issue cuz i turned it on few minutes after getting out of the coldRemove the battery from the PC...
Let everything sit in a warm dry place overnite.
In the morning try again with only the AC adapter hooked up...if it WORKS let it warm up for an hour...then power down...reinstall the battery and give it a full 6 hour charge before trying again.it should WORK without the battery, though.

If it does, your battery is shot and you should replace it. Lithium becomes very VOLATILE when exposed to water so you don't want to take any risks with that.

If it doesn't, then charging the battery won't really help resolve the issue I think.
