Travel Technology - Laptop won't power up after hibernation! SOS - help...

Hello Flyertalk. ..

I've been travelling over the last month or so and as such have not used my laptop a lot. The last I used it was about 20 days ago, and at that time, IIRC, I hibernated it instead of shutting it down.

Am presently killing time in transit at HKG and wanted to use the laptop when I realised it wouldn't power up.

The light on the adapter glows green so the adapter is getting the juice but no LED's on the laptop turn on even after holding down the power button.

Any ideas how this might be resolved? Could this have happened due to an excessively long "hibernation" ?

Part of me thinks the issue might resolve itself if I leave the laptop plugged in for a bit and then attempt to power it on...

Any ideas on what might have caused this and how to rectify the same?

Cheers...

What happened is that probably the battery ran out of juice during the 20 days causing the problems. What exactly I don't know but with some research on google I would be probably able to find it out.

I recommend to charge the laptop for a while without turning it on. Then try to turn it on. If it is a Windows machine push F8 during the startup and run the Check Disk tool to ensure no damage happened to your harddrive.

I would think the hibernate has nothing to do with it, if the laptop isn't turning on.

Thanks both of you.

Another thing I forgot to mention. The "charging" indicator on the laptop doesn't come on when I plug in the laptop to the mains however the light on the adapter glows green.

Try this:

1. Disconnect power cord and remove battery.
2. Press and hold power button for at least 1 minute to discharge any stored charge.
3. Connect power cord and try to power up without battery.
4. If successful, insert battery and let it charge up.

This works on most laptop types for problems similar to yours.

Good luck.

Some times if the battery is so low it take a few minute for it to "reboot" and start charging or build up enough charge to even turn the computer on. Sometimes even loner unfortunately. Give it some time.

Also, could it have something to do with the voltage coming from the wall in HK and that somehow effecting whether or not the batter is getting a charge?

The power adapter transforms input voltage into the needed output voltage. Nowadays the power adapter are capable to convert 110-240V of input into the necessary output.

I have seen this work in the past with positive results - 49 out of 50 starting up without problem. It could also mean either a dead battery and you have to get another battery or the power supply, while able to power an LED can not power the laptop. This could be caused by a frayed cable. Good luck!

If it does not power up with the battery removed, the next thing to suspect is the power adapter. Try another one if you can find one, borrow one, etc.

If that doesn't work with an adapter you know is good, it's probably the mother board.

The machine is actually off in hibernation. In Standby the machine is kept on. If you remove the battery and leave the AC plugged in, can you turn it on? Can you measure the AC adapter plug with a DVM?

Seems like this indeed was the case.

The laptop booted up just fine after I plugged it back at home.
