my first computer is here on this link...
But I have created this 'Power Saving Mode on LG Monitor problem' thread for my 2nd Asus computer...
I want to explain everything I have done on this computer over the last 24 hours so you know the situation and why it is problematic...
first of all this computer had been known to have problems not restarting properly, and yesterday when I started it up it was great...I put AVG on it, updated Windows, and downloaded IE7 with 44 other Windows updates, as well as getting rid of IE7 command bar, and google search box which I find unnecessary...and it was all good, and it asked to me to restart after the updates and sure enough when I tried to restart it shut down out of Windows but did not restart properly, instead it just sort of hibernates, not totally powered off and not trying to restart either, and I had to press power button to boot...then everything was OK in Windows, so I tried restarting again but it did the same as before so I pressed power button again...
then I tried shutting down altogether via Start button, but it would not, so I researched it and I checked the BIOS to see if there was anything there that could be affecting restart and power down, but BIOS asked for a password which I didn't have, so then back in Windows I followed 2 different registry fixes that were the following...
fix#1...in regedit: HKEYCURRENTUSER, Software, Microsoft, Windows, CurrentVersion, Explorer...the value of CleanShutdown needs to be changed from 0 to 1...
fix#2...in regedit: HKEYLOCALMACHINE, Software, Microsoft, WindowsNT, CurrentVersion, WinLogon...the value of PowerdownAfterShutdown needs to be changed from 0 to 1...
I did these 2 fixes OK, tried to restart the computer which again did not restart properly, but then when I was back in Windows I tried restarting, and it then restarted the way it should, then I tried powering down fully via Start and it did! So the registry fixes solved that problem...I then dowwnloaded all the media players and apps I would normally have on a computer, including the free version of Malwarebytes Anti Malware which often picks up alot of malware and viruses and trojans that AVG paid version misses, and then transferred some video files into my documents using full AVG USB scan each time I importing files via USB...then I power down fine and went to bed...
today it powered up fine, then I tried installing a Nero CD which would not accept the serial number I entered because Nero was already installed on the first Asus Bad Sector computer, and Nero only allows one computer to run it at a time, but I can;t uninstall off the first computer as its inaccessible...so I gave up trying to install Nero on the second computer and will wait for their response,
and then just hours ago I downloaded a Windows Update for Cumulative Update for IE7, and update for security for IE7, they downloaded fine then it asked me to restart...the restart problem came back again...however this time when I tried to boot up using the power button the LG monitor says 'Power Saving Mode' for a few seconds then goes black and stays as a black screen...when I attempted to plug the first Asus Bad Sector computer with exact same cable and with a different cable and with different power boards all times the video output of the first computer was recognised by the monitor (even though it was just the Bad Sector computer saying disk not readable) - and it was not in 'Power Saving Mode' and had the LED light power display as green the way it should be...but this 2nd Asus computer with the restart problem when I boot up it only stays on green for a few seconds and then goes straight to 'Power Saving Mode' and stays there with an amber colour on the LED meaning it is in sleep or hibernation mode...
The monitor is LG L192WS-SN
Asus Athlon 64 Dual Core Processor 3600+
160 gig(approx 135 gig free space on C drive just before the crash)
Microsoft Windows XP Professional Service Pack 3
Internet Explorer 7
AVG 9.0 Internet Security
BIOS Main Menu:
Legacy Diskette A: 1.44 M, 3.5 in.
Primary IDE Master: TSSTcorpCD/DVDW
Primary IDE Slave: None
Secondary IDE Master: None
Secondary IDE Slave: None
HDD SMART Monitoring: Enabled
Also I can't access the monitor menu when its in this mode...so it is not a fault of the monitor as it can see the output of the first Bad Sector computer 'disk unreadbale press ctrl-alt-del' screen, but cant see the output of the 2nd computer that has restart problems...from the actions I have done in the last 24 hours on the 2nd computer above, what is the most likely cause for this 'Power Saving Mode' to stay on the whole time?...Is there any way I can turn off 'Power Saving Mode'?...if it is a cooling problem how do I fix that, and if it is a matter of unplugging video graphics card then plugging it back in again will that alter anything or any settings in the computer?...Boot CDs are no good because nothing from this 2nd computer is being output to the monitor while the 'Power Saving Mode' is happening...could it be powerboard issues or something else?...it could very well be IE7 download problems, particularly the IE7 cumulative update, as I got problems with both computers just after changing IE7...with the first bad sector computer my problem began hust after uninstalling andthen reinstalling IE7, and then this 2nd computer has problems just after the IE7 update...should I take it to a computer shop who will give me a quote for $30 and charge $59 for an hour labour if needed? If you have any advice at all, please let me know. Thanks.
