Acer Aspire Laptop with Windows 7 Pro 64 bit was working just fine when I walked away from it for a few minutes. When I returned the screen was white and nothing I did could get me back to my desktop. I shut it down and restarted and now there is no video at all. The screen remains black and I don't even see the Acer splash screen. Please advise.

Thank you!

If you can't see even the splash screen then it sounds like either the display or graphics card has died.

Does your laptop have an external monitor port? If so you may be able to use the external monitor to get into the BIOS troubleshoooting and test the graphics card.

Alternately, you may need to take it into a repair shop.

This is often caused by a bad cable. Sometimes moving the display back and forth can bring something up on the display.

I agree, it sound like the monitor or the inverter died. Try plugging in an extrnal mnitor. If it works, I suggest backing up any data files you have on it and possibly take a Windows backup if you installed any apps. Then contact Acer or the the appropriate company for repairs or replacement.

Hope this helps!

Wow, from that video, it looks like Acer has a production defect. It doesn't tell you much, but possibly shows a problem where the inverter cover is secured incorrectly.

Yes, it could be. Where is QC in the production process?

Here is an update - I decided the first thing to do would be connect to an external monitor to try and narrow down the problem so I took my laptop to my basement where I had an extra monitor and connected it. I saw that there was an image on the screen so I went back upstairs to get the power cord and when I came back down there was an image on the external monitor and the laptop LCD. It has been working ever since. I did notice, though, that the time was off by exactly one hour. I am not sure why that was but I reset it and will keep an eye on it.

>>   the time was off by exactly one hour  << it looks like you got a bad contact in the bios battery

remove AC and battery for a minute, and check the bios settings after reconnecting

It worked for a while then started getting a green cast to it. I connected it to an external monitor and the video was fine. Had to replace the LCD.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!
