    Flashing laptop monitor when unplugging power cable


    Hi,

    I have an Acer TravelMate 3260. I have only had the computer for about two months so the battery is still relatively new.

    When i unplug my power cable the monitor flashes (black screen black screen very fast) but when its plugged in its fine.

    I have tried setting the battery usage to to maximum battery life (i.e. lcd functions at min) but the same problem occurs, I have also tried leaving it flashing (about 5 minutes) nothing changes.

    Im pretty sure its a battery problem but hopefully you guys have a solution or some tests i could run to find one.
    Thanks.

    Hi Zanc and welcome to Dev Shed.

    Does the screen stop flashing at any point ? Can you see the screen ?

    I can see the screen between the black flashes. The strange thing is that it has stopped doing it, which i dont think is such a good thing.

    I think the problem is a bit bigger as when i unplug the power cable and reinsert it my computer trys to connect to the internet through the local area connection but then says a network cable is unplugged this all happens after i replug the power cable.

    I think its mad computer disease... Any ideas.

    Sounds like your laptop may have some faults although, this could be the work of an infection. When was the last time you ran a thorough Anti-Virus scan ? I would recommend doing one now.

    Ok, have run full system scan and no viruses. The strange thing is the power cable problem has vanished.

    Now the s/pdif port is not working (this has happened once before but the problem resolved itself (AGAIN)). I am using the same headphones (have tried others) but the is no output from the port (there is still output from speakers when no jack is plugged into the s/pdif port).

    I really think it must be a manuf error. But do you have any idea what part could be faulty - something that links to the monitor flashing error, the power cable confusion and the s/pdif problem.

    This is what happens when you buy an acer Travelmate 3260. Its toooo cheap!

    New strange thing. The s/pdif port is working again after several days of nothin, but now it is also some how picking up on sounds in the computer (When i type the sound is projected in my headphones, i can hear the dvd rom spinning through my headphones but i am also getting audio output from any media playing.)

    This is all very strange!

    Any ever hear about something like this before?

    Is this in addition to the screen issue !?
