Please I need help with my new laptop 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 your notebook (everything) next to a heater, not too close, for a few hours. Remove the battery, remove the ac adapter - hold down the power button for about 40 secs. Try again

cheers ...

When I tried turning it on an orange light keeps keeping and then nothing more. I don't know if that means a motherboard problem

To the best of my knowledge, cold doesn't cause direct damage to computer components. The damage is probably caused by water vapor freezing to connection points. Does the computer run with the AC cord plugged in but the battery removed?

Most components on a motherboard are spec'ed to 0 Celsius operating, or often -40 Celsius storage.
But usually the whole package has lower margin. And indeed, based on a search I just did, it looks like the baseline (cold) specs for this device are:

-20 Celsius (-4 F) and a relative humidity of 5% to 95%. All for the non-operating (shut down) state.

For cold temps, usually the silicon ICs have no problem (assuming no moisture), but you could suffer mechanical stresses due to the cold temps--> you might have open circuits around some of the package pins due to uneven shrinkage of the various materials (tin leads, solder balls, fiberglass motherboard material, etc. all shrink and expand at slightly different rates with temperature).
