View Full Version : [all variants] HP dm4-1150ea cannot wake up

Has anyone had any experience of this laptop with ubuntu?

When the lid is closed, it goes to sleep as normal but if it is left for more than about 5 minutes, wit will not wake up.
The power light and wi-fi light both blink but no sound from the hard drive and no wake up.
Once in this state I cannot do anything with it, it won't even power off and I have to remove the battery to get it working again.

It only seems to happen when on battery, it wakes up when plugged in to the power supply.
This also happens on Windows 7.

Looks like I will have to return it for refund unless anyone knows of a linux workaround (since windows isn't really used).
