HP 6715b Laptop Power

English Hardware
#1

Hey all,

I got a weird issue that I am not sure how to resolve. I have an HP 6715b running OpenSuse 11.1 64bit. Everytime I unplug the power from the laptop to run off the battery, the screen goes black. I am unable to get back to a normal screen without rebooting the machine.

Has anyone else seen this issue or have an idea on how to fix it?

Thanks,
Dave

can you try to run the development release, maybe it gets better drivers and fixes the ACPI/power management issues in your laptop.

Which desktop environment are you using (KDE4, Gnome…)? I remember an old thread on this topic. The OP claims to have fixed the problem relating to a problematic ATI driver/chipset. However, they didn’t post the solution :frowning: And another [here.

Looks like it was a widespread problem with this model. In particular, this post by Mirjam Tesser may be of interest

What worked for me :

Manually deinstalled all pre-installed HP Ati Software / reboot

Download / installed latest Ati X1250 driver from Ati.com w/o Catalyst control Center

Have a
6715s / F.0B Bios

No black screen since!

Hey all,

Thanks for the help on this one. I am currently using Gnome. I don’t remember this being an issue with 11.0 although it’s been a while since I have run that version.

I don’t really want to download the new development version and install just to see if my issue goes away. That is a large time commitment. I am hoping to get this resolved so I can use the laptop and OpenSuse to do some work. Although I may have too as a last resort or go back to 11.0

Thanks for the help again,

Dave

Hi Dave,

this problem has nothing to do with the GUI versions. I bet you have ati driver installed.
The only thing you have to do is to remove it and your suse is going to work fine (except that you wont have hardware 3d support).

Hay there,

I have the same laptop with the same problem… kistej is correct that removing the ATI driver solves the issue, but there is an alternative that I have picked up and am willing to live with.

Once you either plug/unplug the power to the laptop your screen goes black. Now press CTRL+ALT+F1 to switch to terminal mode, and then without even logging in, press CTRL+ALT+F7 to switch back to GUI mode…

Works every time for me, and saved having to remove the ATI drivers…

Hope that you come right.

Dredger.
