Acer 3935 question and potential problem (?)

Hi All,

just registered here. I' ve recently bought an Acer 3935 (couple of months now). I' ve been really pleased with the laptop, however I noticed an odd thing the last few weeks.

I was running the laptop on battery, as I often do, when with approximately 1 hour or less (balanced profile), the colours on the display suddenly got "washed out". There is no, sort of, technical way of describing the effect, it looked like when you turn the brightness and contrast way up and the colours just bleed and appear washed out. But in this case it was the whites that looked just like that, and everything looked like it was displayed in 16bit colour (but not exactly if that makes sense).

It is not a regular or recurring problem, it has happened a hand full of times so far, but for a 2 month old laptop any problem like this is not to be expected. Everything else seems to be running happy, and the laptop seems to completely unaware of this display problem (all colour settings are unaltered etc).

Also, I haven't been able to recreate the effect by running it on battery and seeing what happens. When it did happen, there was no apparent reason to cause this.

Any suggestions would be greatly appreciated.

Thanks in advance

 

Do a clean install (From a Windows 7 iso disk) and grab the latest driver from Intel not Acer most likely lousy outdated Acer drivers(They never really bother to update their sites).

 

Actually, I' m still running the native Vista that the laptop came with. I' ve yet to install Win7 on it.

thanks!

 

Any suggestions? The same thing just happened again, no apparent reason. It's getting a bit annoying.

 

do a bios updated first !!

screen is bleeding to white wit vage coler lines disapering to total white screen. lcd or vga or lcd cable.
wat you can test your zelf , reconnect lcd cable on lcd and mainboard

 

intel video? open up the intel graphic properties from the system tray. under the "display?" look for the power options. uncheck the DPST (display Power Savings Technology" and see if that helps.

 

Yup, that's exactly what it was. The colour change was due to the graphics card trying to save battery. Doing that it cause the colours on the display to appear washed out.

Discovered couple a days ago, just before reading your post. There are some mentions of this Intel Display Power Saving Technology causing problems in a number of laptops. The annoying thing though is that even if I disable it, I think it revert back to its default "on" when I turn the laptop back on.

Intel take notice!!
