CD drive missing

[Amrin]

My CD drive is missing from my computer when I us my laptop with battery. But when I use laptop with fully charge and plug in AC my CD drive is not missing. Anyone help me please!

1. What particular laptop model/brand and operating system do you have?
2. Is it a replacement or old but still reliable battery?
3. Any particular changes, updates before this issue started?
4. Your CD drive is the internally connected drive and not an external cd drive?
5. When you say missing, it cannot be found on both Windows Explorer(My Computer) and on your Device Manager?
Please Answer this Accordingly. Have you tried to remove first the battery and directly connecting AC power adapter on the laptop to see the difference? You mentioned its only when battery is fully charged and plugged in.

Thank for reply!

1. My laptop brand name is Acer 4736z
2. Operation: window 7 32bit(Ultimate)
3. I use original battery(not replacement) with external CD drive.
4. CD drive missing from both Explorer and Device manager.
5. CD drive: DVD-RW

   CD drive is missing when I use laptop with battery and not fully charge. No problem if I use laptop with AC power and not plug in the battery or plug in the battery with fully charge. what should I do to bring it back?

external CD drive

Ok, its an external optical drive powered by USB ports.  Try connecting the drive on another working PC. Are you sure its an external drive? Not the one thats connected to the laptop?

Follow the link Patio gave you. Click on the Patch and follow the instruction afterwards.

Dead CD drive then...

But since it's a laptop try ejecting and re-seating the drive...with all power off and the battery removed.

In the instance when your cd drive is not detected in Windows explorer and Device manager, try disk management to check for the drive.
Hit Start and type disk management on Search programs and files box,  Enter. Your hard drive will be reported as C:(drive) and optical drive as CD-ROM  0(DVD, either D:, E: or F:). Is it also not shown? You could also restart PC, then tap F2 to check on your BIOS utility setup. The information will display also your Hard drive description(Hard drive model name) and optical drive (or ATAPI model name) for your CD drive. Is it also there or not? Do this when CD Drive is not shown as you posted and mentioned above. This is a rare case actually about your drive connected to power adapter or battery being low would cause that effect.
