Title: How could a flat motherboard battery cause colour distortion on my computer?
Post by: syhprum on 28/10/2015 20:04:34

I my dining room I use a Samsung 22" monitor both for TV and computer display.
recently I had a strange problem with the screen colour on computer use with everything glowing red.
Like most nerds I assumed it could be cured by software but got nowhere, eventually after trying a different NVidia card that was OK in another computer which stopped the computer working completely by disrupting the BIOS I thought to test the BIOS back up battery and found it down to 1 volt.
Replacing it cured all the problems !, should I have tried this earlier (the computer is of 2008 vintage rescued from the town dump)

I should have been alerted to this problem as the first date displayed on the screen was often wrong.

I had date problems on more than one occasion, which were caused by the battery going out.

The BIOS system on the Packard Bell motherboard does in fact display the battery voltage if you look in the right place, it will be one of the first things I will look at next time I get strange computer faults.

Well..., i missed by far thinking of STDOUT , "SVG color map" and "color depth" registered with the driver and its hardware port - BUS...

I'm quite surprised that the board battery going out was causing colour distortion. When the machine is running there is no role for the battery; are you saying that the colours remain resolutely uncorrected when the computer was live and the card was adjusted?
