then you choose product model.... then OS.... then driver you need

Faulty wiring

Take out the battery and replace after some mins. If this doesn't work, remove the ram and place it back

I would guess the drivers are either not installed, or the wrong ones are installed. Go to the Acer website and select your model and download the current drivers from there and install.

I suggest that you can use the other method to eject: press start and go to my computer, select the disk drive and you should see an eject option in the menu bar.Remember that disk drives are subject to computer admin and do not respond quickly to a button press, especially if a disk process in taking place...

You should first check if in your Device Manager your Network Card is being recognized, and make sure there is no errors (a yellow triangle would be displayed). If it is there, you can try uninstalling and reinstalling the drivers.
You can also go into your BIOS setup when starting up the computer, and make sure it's enabled. If none of this works, to get your WIFI Fob working, you probably need to disable your Network Card first in the BIOS before your Fob will work.
Hope this helps.

Here is a link: http://www.acer.ca/ac/en/CA/content/drivers

From here, choose 'Notebook', then 'Aspire', then on the next box that appears, scroll down to '5820T'. A new window will appear; click on the 'Document' tab, and the first listing is for the Generic User Guide (click on the orange arrow on the left of the listing).

Hope this helps.

Try pressing Fn + F5 after connecting the HDMI cable.
