Severe problem, random power cuts
This is my computer: (linuxforums refuses to let me post the link to the manufactuer's page. ) It's a Gateway ZX4800
Graphics card: Mobile Intel(R) 4 Series Express Chipset Family (GMA 4500, I think. Something to do with "i965")
CPU: Pentium(R) Dual-Core CPU T4300 2.10GHz
Hello. I like using Linux. It's fun and I love learning about it the more I use it. The problem is that my hardware doesn't seem to be supported, or isn't configured properly.
I've tried many times to get help in the openSUSE IRC, and by searching with Google. Neither have helped.
I have openSUSE 11.3, 64-bit, Gnome edition installed on my computer. It has many issues that I think may be related. I would appreciate any help as these are my only obstacles with using Linux full-time, and I'm afraid they might be damaging my hardware.
-Rarely turns the fans on, causing my computer to overheat often. As a workaround, I set the fans to constantly run at 100% speed in the BIOS.
-The backlight dims a few seconds after I stop moving the mouse or typing, then it brightens back up to whatever level it was previously at. In other words, it fades out and then back in whenever I stop or start using an input device. If I use my mouse while it's fading out, the brightness gets stuck at whatever level it's at until I manually change it. This only happens under Gnome as far as I know. This happens regardless of what my power manager settings are. I've tested them all to no effect.
-(The Severe Problem) The power on my computer randomly cuts off, with no warning. It happens as if someone pulled the power cord out. This can happen every 30 minutes, or not once for days. The only time I've been able to duplicate this is when adjusting the backlight brightness in the Gnome power manager. Sometimes it will cut off when I do that.
-Also, the speakers used to emit a hissing noise that sounded like some kind of feedback from the hard drive. This only happened when I plugged headphones it, and did not affect the headphone's sound, only the internal speakers'. I have fixed this by setting "snd-hda-intel model=toshiba". The only reason I bring it up is because I think it could possibly be related to the other issues.
Setting "apm=off" doesn't seem to do anything. I can't use "acpi=off" because that disables the LVDS output of my video card.
I can boot into openSUSE, but I don't want to do anything that might jeopardize my hardware. I don't have the money to replace my computer, or any of it's parts, if they get fried. So, keep this in mind if you want me to try some settings for testing purposes.
If anyone can help, please do.
