problems with HP a220n/monitor and Knoppix....
Ok here's the deal, I am currently running a HP a220n desktop machine (with stock mx703 monitor) which was recently upgraded with a 160GB 7200 RPM Western Digital hard drive, and a MadDog Multimedia 16x Double Layer DVD burner(16XDVD9A2) as well as a MadDog SurePower 350W(400W max) power supply to support the new d ...
Ok here's the deal, I am currently running a HP a220n desktop machine (with stock mx703 monitor) which was recently upgraded with a 160GB 7200 RPM Western Digital hard drive, and a MadDog Multimedia 16x Double Layer DVD burner(16XDVD9A2) as well as a MadDog SurePower 350W(400W max) power supply to support the new devices.
Before the upgrade, when we were using the stock power supply and stock components, Knoppix Linux worked fine, detected all components fine and everything, but now, for some reason, right after it has set all the device settings, and where it usually clicks and displays the OS component loading screen, the monitor displays the "entering power saving mode" screen. I have tried different command line options to varying degrees of success, with "VGA=normal", it manages to load into the desktop, sees all the drives and everything, but just as I am about to enter an URL into Mozilla, the monitor clicks and goes into power saving mode. Now, the very first time I used Knoppix after the upgrade, I was actually able to use it for like 10 minutes before it clicked into power saving mode...which I don't believe it is actually in, as in Windows the system LED actually flashes when it is in low power mode, and even though the monitor LED is orange, I can still see the CD status light going and the drive is still humming, and the system LED is solid. I don't understand why it would work fine with the old power supply (which was found to be defective when tested with a power supply tester), and now it refuses. All the new components are recognized and work to their fullest capacity in Windows XP, and the power supply and low power modes work as expected in Windows XP. I even turned off all power saving modes in the BIOS to no avail.
I have tried several different LiveCD distros, with the same results, I have tried numerous resolution changes and other command line options with little effect...I am really at my wits end here, I enjoy using Knoppix, but I am ready to give up...this is very frustrating. Any help you could provide would be GREATLY appreciated.
My system Specs are as follows:
System Model: HP Pavilion a220n with Pavilion mx703 monitor
(nForce 2 chipset with integrated sound, video(disabled) and network card)
RAM: 768MB
Video(Integrated GF4MX has been disabled):PNY GeForce FX 5200 128MB
Hard Drives: Seagate 120GB 5400 RPM(stock), Western Digital 160GB 7200 RPM (upgrade)
Optical Drives: JLMS DVD-ROM Drive(stock), MadDog Multimedia 16x Double Layer DVD burner(16XDVD9A2) (upgrade)
+DSL modem, printer etc. (not really relevant, but I felt compelled to include them)
Thanks in advance for any help you can provide, and I apologize for the length of this post, but in this case, I felt elaboration was necessary.

OK, let's recap.
The battery went dead for the bios, which means that you lost the old settings. You apparently reset what the old settings were supposed to be.
Try getting into the bios setup (make a note of what the current settings are). Pick the option to set the default values. Then see what happens.
If the problem does not resolve, try getting back into the bios settings and set PNP OS to off. While you are in there, make sure that the new drive is recognized correctly (brand and total capacity). Note if the drive(s) are set to auto for detection or LBA. It should be the setting on the far right of the drive descriptions.
See if then setting PNP OS to off has any effect. If not, report back. There is one more thing we can try.

already tried the PNP OS setting, made no difference. As for the drives, the correct capacity and brand is detected, and the LBA setting is auto.

Is it possible Knopppix linux uses stricter power requirements than windows? is there any way to turn off DPMS with a cheat code? I have tried unplugging different USB devices, and disabling DHCP with varied success - I just don't understand why sometimes it boots in fine for a minute or two before clicking into standby - it always worked fine before, and if the BIOS were compromised, I wouldn't even be able to boot into windows - would the fact that the new power supply has a fan speed and power switch have any bearing? Probably not, but I am mystified. It worked fine with same monitor, video card and motherboard before the new PSU, HD and DVD burner were added, and it IDs the new hardware correctly, so why won't it work? I really don't feel like ripping the new PSU or hardware out to boot Knoppix, and I don't see why I should have to. I apologize for rambling, but this is very frustrating, I am a newbie to Knoppix, but fairly experienced with computers in general. Thanks in advance for any light anybody can shed on this - I have been scouring the net, and the solution for this problem is always cheat codes, which do little, if anything for me.
