In device manager, delete something like a USB device and perform a hardware scan with the menu item and it will detect the optical drive if its running ok. Then you can upgrade the driver for motherboard or the cdrom if exists on their web site. If the issue persists, check BIOS and see whether it is disabled in any way before you try to disassemble it and tighten the cable connections or try that cdrom on other machines.

SOURCE: cd/dvd rom not working on hp laptop

Is the Drive detected in the BIOS? Can you boot from your Windows or any bootable disc? If so try this solution:

Always backup your registry before editing and use care to find exact key!
Start Registry Editor (Start, Run and type in regedit then click)

Find "UpperFilters" and "LowerFilters" (and "UpperFilters.bak" "LowerFilters.bak", if they exist) value under the following key in the registry, and delete it:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Quit Registry Editor.

Reboot.

NOTE: You might need to reinstall any CD recording apps you have, if they start to not work completely, after doing this.

Cd/rom drive

Don't know what Operating System you are using, but go to Device Manager.

[Win XP: Start > Right-click on My Computer > Properties > Hardware tab > Device Manager

Win Vista/ Win 7:
Windows logo button > Right -click on Computer > Properties > Hardware tab > Device Manager ]

In Device Manager click on the + sign next to DVD/CD-ROM drives.
Right-click on the Name of the optical drive. (CD/DVD drive)
Left-click on -> Uninstall.

A Microsoft 'Squawk Box' will come up, "Warning you are about to uninstall this device"
It is OK. Click on OK.

Close all windows, go back to your desktop screen.
Restart your computer.

[WinXP: Start > Turn Off Computer > Restart
Win Vista/Win 7: Windows logo button > Restart ]

When Windows FULLY loads you will see a pop-up out of the system tray, "Found new hardware device", and perhaps another one, "Found XXXX CD/DVD-ROM drive"

(XXXX being the manufacturer name)

Ya gotta love Windoze. Looses the address to drivers.

[Driver: Small piece of software that allows the Operating System to communicate with a device.

Optical drive is the device, do not know what Windows O/S you are using ]

If that doesn't do it suggest start looking for a replacement optical drive. An optical drive is a mechanical device. As such it has a 'Life Cycle'. Yours may be at the end of it's.

[ALL power removed. AC adapter (Charger), and Battery.
Turn laptop over. There is usually one screw on the bottom to remove, then the optical drive can be slid out. Need exact info post the laptop manufacturer, and model number. Model number is on the Bottom of the laptop. Product Number (P/N) for HP, and Compaq; in white Service Tag on bottom ]

My computer no longer "sees"

hello
at end of this instruction set, see link to review more questions/answers,as your issue with CD/DVD ROM will vary .


This document applies to HP and Compaq desktop computers with Windows XP, Me, and 98. Use this document to make Windows and the CD writing software recognize the CD or DVD writer drive. Start at Step 1; do not skip to other sections until Step 1 has been completed. Step 1: Does Windows detect the CD or DVD drive? Use Device Manager to determine if Windows is recognizing the drive:
  1. In Windows XP, click Start , and right-click My Computer . In Windows 98 and Me, right-click the My Computer icon on the desktop.
  2. In Windows XP, select Properties , click the Hardware tab, and then click the Device Manager button. In Windows 98 and Me, select Properties , and click the Device Manager tab.
  3. Click the plus sign (+ ) next to DVD/CD-ROM Drives (or similar) category.
  4. Do the following depending on what is listed in the DVD/CD-ROM drives category:
    • If the CD or DVD drive name is missing , the drive is not being detected by Windows. Close Device Manager and skip to the section CD or DVD drive is not recognized by Windows .
    • If a drive name is shown but is disabled (icon is marked with a red X, c00877300.gif ), the drive has been disabled. Right-click the drive name and select Enable . You may have to restart the computer to complete the enabling process. The drive should work correctly once it has been enabled. NOTE: If the drive cannot be enabled, a required service or driver that the drive needs is not functioning or has been disabled. Click the plus sign next to IDE ATA/ATAPI controllers and troubleshoot any problems found according to any error codes in Device Manager. Resetting the BIOS may also resolve this problem.
    • If a drive name is shown but contains an alert icon (an icon marked with an alert symbol, c00877301.gif ), then use the section Using Device Manager error codes to troubleshoot the problem. You may also use the next section Disc burning software does not recognize the original drive to reset the drive configuration.
    • If the CD or DVD drive is listed as normal but your disc burning software does not recognize the drive, Device Manager shows no special icons c00877302.gif . Windows is detecting the drive but the writing software does not. Leave Device Manager open and continue with the next section Disc burning software does not recognize the original drive .

My dvd writer no reading or writing

hi there,

Does the light flash on the front when a disc is inserted or have you recently installed it as a Primary/Secondary optical drive? Plus, just as a matter of interest it will only read DVD's & read/write CD's.

Your problem could be down to a number of causes including a corrupt driver, where you will have to uninstall the driver by going into Device Manager, clicking the + sign in front of 'DVD/CD ROM drives,' right clicking on the Optical Drive in question, clicking properties/Driver Tab/Uninstall (Advanced).

This will remove a corrupt driver & when you restart your system the Hardware Manager will recognise the said Combo Drive & reinstall the driver.

If it is only unable to read DVD''s then you may require the necessary Codecs for your preferred Media Player, to support various file formats. I wish you the best of luck.

Kindest regards

Ste

The cd drive dosent work, lights dont come on and whem i click on my computer, it dosent recognise any cd drive on the laptop. the device manager says it's a device problem.

The optical drive sounds as if it's no longer functioning. The first thing to try is change the CD drive, which in a laptop will be rather expensive. One way to circumvent the problem temporarily is to get an external optical drive.
