I have an Acer 5100 series, lately my laptop will not read any discs, when i put in a CD the light blinks yellow a few times and then just goes black. when i check it says its working properlly. i have cleaned the lens and that didnt change the anything.
It sounds like the laser may have went out. When reading a disc the laser moves up and down as well as back and forth. It sounds like it is reading from the wrong position if it's reading at all. Remove any disc from the drive. Go into the device manager and remove/uninstall the drive from the list. Reboot the computer, wait until the hardware wizard reinstalls it and then try reading another disc. If this doesn't help then most likely the laser has went bad. It is not an uncommon problem. You can also see if there is a firmware update for your drive from the maufacturers website or your PC speciffic website. Hope this helps.

Turn on your computer and open the CD drive by pressing a
small button on the front of the drive. Use a can of compressed air to
clean the lens by spraying a few squirts of the air into the drive. This
will fix disc skipping if there was dust on the lens.
Place a CD drive cleaner into the disc drive. This is a disc
that is specifically designed to clean CD drives. Allow it to run for a
few minutes, and then extract the disc from the optical drive.
Click the "Start" button and then click on the "All
Programs" option. Click on the "Windows Update" icon and then click the
"Check for Updates" button on the left side of the screen. Click the
"Install Updates" button at the bottom of the screen to update the
drivers for your CD drive. Restart your computer for the driver changes
to take effect.
Unplug the power cable from your computer and use a
screwdriver to open the tower door. Locate the CD drive cables inside
the computer. Make sure that the CD drive cables have not loosened. If
the cables are loose, then the drive will not operate properly.
To run the check disk utility you will need a repair disc ora operating system disc. Put the disc in the cd drive and boot fromit. You want to get to the Dos Command Prompt (Black screen with whiteletters) and type the following command: chkdsk /r Check disk will run well over an hour or two and you will notice thepercentages going from high to low, this is normal. Let it run tocompletion. Then reboot machine.
If check disk fails to solve your problem you might have to reinstall windows.Try doing a Repair Install that way you don't loose your data, documents,music, pictures, videos or programs.
In windows xp you get to the dos command prompt by selecting R for repair whenthe options appear.
In Vista and Windows 7 you want to get to the recoveryconsole and look down at the bottom of the window for the Dos Command.
The problem is that the Drives lens is already bad and cannot read any disc, no matter the type of disc you put into it, it wont read it still. The solution is to replace the drive. Replacing it is the best way to solve the problem. If not trying to replace the lens is going to be futile as the lens for the driver is not available and when you install a new disc drive, it will have to install the drivers software.
If you replace the lens, the laptop wont be able to install the drivers of the lens as it reads it alongside the driver itself and if they are not compatible, it wont install the drivers software. So my best advice is for you to replace the CD drive.
My laptop is a typical example because my disc drive is also bad. And i had to replace the drive and not the lens.
I think somehow you've turned your CD drive off in BIOS. Turn it on again (if you don't know how to do it, post yout BIOS version, I'll try to help. BIOS version shows somewhere on the screen when you just turn on your computer. For example "AwardBios v.XXXX)
You can check the BIOS to see if the drive is recognized and even attempt to boot from the drive using a bootable CD to verify it is functional (if using the Windows disc - just verify it reads - DO NOT REINSTALL)
If the drive works use the following to get the drive back in Windows:
Always backup your registry before editing and use care to find exact key! Start Registry Editor (Start, Run and type in regedit then click)
"UpperFilters" and "LowerFilters" (and "UpperFilters.bak"
"LowerFilters.bak", if they exist) value under the following key in the
registry, and delete it:
To manually open the CD Drive, straighten a paper clip and insert it into a tiny hole in the front of your CD drive and push the paper clip gently into the drive and the tray should then pop open.
Open and close this several times, then insert a disc into the drive and see if it will read the disc.
If not the drive is dead and needs to be replaced.
