HP Omnibook 4150 hangs when coming out of hibernate mode

[David L. Largent]

About half the time my HP OB 4150 "hangs" when it is coming out of hibernate mode. The rest of the time, it works just fine!

With the PC off, I push the blue power button, and it starts the power-up process - disk starts spinning, lights start flashing, etc. Then about the time it should be displaying images on screen, the screen is left completely blank, except for a single "underline" character in the upper-left corner. Everything seems to be up and running - even have my network connection - just nothing on the screen except the "_".

Any thoughts?

Did you ever get this problem resolved? I am having the same problem on my OmniBook XE3, but it happens every time I hibernate. It just started last week, possibly at the same time that I installed a USB mouse. I have uninstalled the mouse, installed W2K SP2 and followed the instructions on another thread having to do with changing the USB driver, but it still hangs. I ran into a dead end on the USB driver when it came to downloading a new one from Intel because I don't know how to find out which USB chipset I have on my machine.

These behaviors also can occur if the power management drivers on the computer
are not compatible with the Windows version you are currently have.
