This issue can be caused by a few things. my first suggestion is to delete the upper and lower filters, you can follow this kb document from microsoft http://support.microsoft.com/kb/314060 for step by step instructions on how to do this. If the problem persists try using microsoft's restore manager to go back to a time when the device was properly working. If all else fails you may have to replace the drive.

    upper and lower filters are registry files that often become corrupt and inhibit your dvd or cd drives ability to function correctly. Simply follow the steps from microsoft ( in the advanced troubleshooting section) and then reset your computer. Your drive should work when you restart!

Fix it yourself heres how: purchase a replacment dvd drive heres an example of one you could purchase that will fit your model http://cgi.ebay.co.uk/ACER-EXTENSA-6602-DVR-K15RA-DVD-RW-LAPTOP-DRIVE-7865_W0QQitemZ330344511659QQcmdZViewItemQQptZUK_Computing_LaptopAccessories_LaptopDrives?hash=item4cea1138ab#ht_1313wt_732
Most dvd drives from any acer extensa will fit your model with the relevent bracket, which you will already have connected to your broken one.
ok now veiw the service manual here Service Manual and go to page 57 chapter 3 (67/142) here you will find the section called removing the optical drive module. its really simple just follow the instructions and pictures carefully.
Hope this Helps! Please Rate!

Play/open dvd


If this is the DVD drive that was originally installed in this machine you should be able to go into device manager and update the drivers for the dvd-rom. The drivers should be located the driver cd's that came with the laptop.

I have an acer extensa 5420 and the disc drive will not play cds or dvds


Hi, your pc might have a hardware problem issue.
The disc drive might have gone bad already and need to be replace it. If the laptop is still under warranty, I would go ahead and consult with the manufacture for replacement.
yourcan verify if the window is cause the problem by right click on My Computer icon on your desktop and select Manage and Device Manager. If you can see the DVD/CD ROM drive status with Plus sign next to it, click on the plus sight and you should see your dvd/cd rom drive install on your Laptop. This mean window is reconizing the device but the device doesn't read the disc because it has a problem.
Hope this help.
