i got the aspire 5810t and have the same exact problem.i got it for christmas and ordered windows 7. waited a week and a half, got it, and the first two discs worked fine,but when i tried to get the disc out after it restarted,it wouldnt come out. i tried for an hour to get it out but it didnt work,so i tried to turn it off. but it got stuck on the logging off page, so i turned it off manually.when i turned it back on the disc came out, so i put the 1st disc in again to finish the upgrade. i had a few problems with last part, but i guess that can be blamed for "disc not coming out" problem. now sometimes it freezes up when i use firefox, and i have to restart the computer. i havent had the screen go black yet,because i am propably always using the mouse.the computer takes an extra long time to start and is slower.their are a few other little problems, buti wont get into themhopefully we find an answer.
Two weeks ago I purchased an acer timeline 5810T and was in perfect condition running windows vista. I applied for the windows 7 upgrade to be sent to me via email almost immediately after taking the laptop home. In my anxious attempt to try out the new windows OS, I kept my computer safe only using it a couple of times to prepare it for the upgrade when it came in the mail. Finally after about a week of waiting, the much anticipated upgrade came in, and I had successfully installed windows 7.During the installation process, after installing the upgrade, I had to change CD's to finalize the three step process. I was surprised to find out that the cd drawer wouldnt open on comand, so I used the little paper clip trick. When the CD wouldnt autolaunch I restarted the computer and completed the last step of the upgrade. Finally windows 7 was installed, and I went to bed and left the laptop open as it was restarting itself. When I awoke the next morning, I found out that the computer was still at the "shutting down" phase of restarting. I manually shut down the computer and started it up again. Later I installed Adobe Cs3, and it required a restart as well. The same thing happened and i was required to manually shut it down and boot it up again. Also i've found out that if I leave the laptop open for an extended period of time, the screen will go black and there would be no way to get the screen back, like wiggling the mousepad or tapping the power button or anything, not even opening the or closing the laptop. I really dont understand what in the world is going on with this laptop, but If anybody could please offer me any help it would be greatly appreciated!!!
