No audio after swapping dvd drive

[ell]

Hi, I have an old HP Pavilion ze4900 that I've swapped the dvd rom drive with a dvd rw, and now I have no sound. The conexant audio shows a yellow ! in device manager, I've tried the usual, uninstalling/reinstalling the driver, tested with headphones,no go. (no viruses either, it was working until I swapped the drives) the only steps I did was remove the keyboard cover and the keyboard and the dvd drive. I checked the speaker connectors they look fine under the keyboard cover, I'm stumped. No sound in linux live cd either, could it be the dvdrw drive is not compatible? It seems to work fine in it.

Remove the DVD drive, reboot see if the audio works, you might want to uninstall and reinstall audio. This will tell you if the DVD drive is causing any issues on the PCI bus or something weird in the southbridge.

yeah, I did all that, its toast, now all I get is lights, even with everything removed, checked ram too. Mobo must be dead, its my daughter's of course, shes had it for 8 years and you'd think I just killed her best friend, ugh. Would like to know what I did though. I imaged the drive and am putting it on a donated gateway, hope that goes smoothly or I am really in the dog house!

First the audio went dead and now the whole mobo is dead ?

Weird, I wish I could help you more but when good goes to bad and then worse I can't help this way. Still think the board IS ok but there is more to it.

Well, to begin with all the usb ports failed her, so I purchased a pcmcia usb card, she wanted to burn a dvd but her drive was only dvd rom, I swapped the drive with a dvdrw that I had, install was simple, pop the keyboard and the control panel top cover and slide in the other drive. Thats when things started to go down hill, the sound disappeared, I thought the usual suspects, drivers, conflicts, but when I booted to a linux cd and found still not sound, i figured something was broke. I backtracked my steps, the only thing I could think of was when I took the control panel cover off it was close to the speaker connector, but there was no sound in headphones either so I doubted that. I removed the dvdrw, rebooted, now no post, nothing, just power lights. Pulled the hard drive and checked ram, still nothing. Heres the kicker, the laptop i set up as a replacement for her with her imaged drive, turns out to have a bad dvdrw drive AGH!

I removed the dvdrw, rebooted

You where not swapping out the drives with the unit powered up, right?

no, weird. I just don't want this happening with a customers pc, really would like to sort it out, I've never killed a mobo before.

Edit: Just realized this is a laptop we're talking about. Did you try putting the old DVD drive back in? Also, double-check that all the connections on/under the keyboard cover (power button board, etc.) are OK/secure, and make sure the keyboard connector is also making good contact.

I did not put the old one back in, good idea, but that would surprise me, but maybe the system/sound is just tuned to it?! never had issues swapping a dvd/cd drive, I thought they were all pretty much universal???

Yeah, it's really strange. I know with the old desktop 5.25" optical drives, sometimes you had to hook up a special audio cable to the motherboard to get the audio to work (or something like that), but yeah.

Well, let me get this right. Before you worked on it, the USB ports died. Then you just swapped out the drive, and the sound died. Lastly, it completely stopped working.

Sounds to me like a bad north gate chip, specifically cold solder joints. As you worked on it, you flexed the motherboard slightly, lifting another point. Continued to work on it, last straw and another solder joint failed.

Try re-flowing the board if you think it is worth while, she is an old mobo.

Yes, I'm thinking something like that must've happened, thank god it was daughters! I'm too busy these days to tinker with it further, D local newspaper website got infected with a virus and passed in on to everyone in town!)
