HP Probook 470 G1 with faulty HP DVD-RAM UJ8DB

HP Recommended

Hello community,
A few days ago I’ve updatet a HP Probook 470 G1 with Windows 10 x64. The laptop works fine with this OS. No problem so far.

After this action I’ve checked the HP Probook 470 G1 support page for hardware drivers and found a lot of new drivers. I’ve downloaded the most recent available drivers for almost every system component. The list grew to allmost 30 drivers, including the new BIOS firmware, L74 Ver. 01.47.

First I’ve updatet the BIOS without a problem. After installing about 20 drivers, Windows told me after a reboot that the OS was seriously damaged and had to revert to a earlier restore point.

Windows restored itself, I after that I discovered that the HP DVD-RAM UJ8DB doesn’t respond. For example the eject button in Explorer doesn’t work. I have to force open the DVD bay (by paperclip) an when I load the player with a random audio CD nothing happens.

When I shut down the system, wait for a while and boot Windows again, the audio CD (sometimes) plays normal. If I eject the CD and remount it, the player is dead again.

In Device Management I see no problems.
Maybe the installation of the HP drivers wasn’t such a good idea. Luckely I’ve made a backup of the whole system before I started the driver installation. But after this partition restore I still have the optical drive problem. So I guess the BIOS update is the cause of this problem.

- Is it better to rely on the drivers that Windows chooses or the specific HP drivers?

- Must I downgrade the BIOS version to overcome the optical drive problem?

- If yes, how can I do that succesfully? I don’t want a bricked laptop.

- If yes, which BIOS version must I use?

- If no, is there another way to make the optical drive work normally again? I have found a similar problem on the HP-site.
