View Full Version : Somewhat serious laptop issue/question
22-10-2007, 02:03 PM
I'm in need of assistance with the KKW tech l33t:
I have a 1-year old Dell Inspiron E1405 laptop. I tried putting in a DVD into my TSSTcorp DVD+-RW TS-L532B combo drive, but for some reason, it wouldn't play. I went to the device manager, and it says the following:
"Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41)"
Clicking the troubleshoot button does nothing.
This just started yesterday for what seems to be no apparent reason. I'd rather not have to refresh the system back to manufacturer settings, but I'm not sure what this "code 41" is...if someone has any spare time, could they assist with my problem? Much appreciated.

i've come across this no end of times, and this solution always seems to work
but be warned, messing with the registry can seriously fuck your machine, so be careful and i accept no responsibility if you cock up.
and delete the keys "UpperFilters" and "LowerFilters" then reinstall the drivers.
and code 41 is the DM code for exactly what it said, its just shorthand for techies.

Hmmm...any less painful way of dealing with it, Ice? I'm afraid I'll cock up.
Backup your entire registry before you play with it. If you fuck it up, boot into safe mode and restore it.

Liam, would you mind explaining to someone as idiotic as myself how one backs up said registry?

Just buy a new laptop. That's what I do lolL!!
To be honest I'm not sure as I've never done a total restore of a registry, I've always solved my problems by formatting and reinstalling Windows. Thats the beauty of an automated backup system, I can do that whenever I like :D
I would assume that you need to start regedit and export a copy without navigating through any of the trees in either of the panes. That should export a complete copy of the registry. I just did it for kicks and the resulting file was about 73MB, which sounds about right.
I dont know whether or not simply running that file will overwrite or simply merge the existing one with the backup one, you'd have to check that out.

you only need to export the bit your editing... don't bother backing up the whole thing. you can then merge just that section back in.
the main problem would come if you delete the wrong thing. If you're inexperienced with regedit, RegWorshop is a powerful alternative with good fail safes

Ok Ice, I'll try the link you gave me and hope for the best.

Real quick, before I try anything...if I fuck up, but create a system restore point before said oopsie, I could just revert to before the mistake and everything would be fine, except the drive's continued problems, correct? Just want to cover my tracks before I make things worse.

It can't hurt. Of course you could banjanx your registry sufficiently that you won't be able to boot into windows, but I *think* in that case you could always use the Windows CD to boot up into the Recovery Console. Don't take my word for it though, wait for Ice to confirm/deny it.

if you really think you will bollocks it up, just back up your irreplaceable documents, and then re-install windows if it all goes tits up.

Thx Ice, I think that's what I'll do just to be safe. Prolly at the end of the semester, since I don't think I'll need the drive anytime soon for school work. I'll just make a checklist of what was on here beforehand, then get everything from the interweb and what have you.
Thanks loads for the support you all. Don't know what I'd do without the knowledge of the KKW...probably something real destructive.

Ice, when you said to reinstall the CD's drivers after changing the registry bits...how do I do that? I didn't get a copy of Windows on a CD with my Dell, I just asked to have it prompt me to do a complete restore at the system start-up if I ever wanted to. Would I have to go into the device manager and try it from there?

Just goes to show how retarded I am that I didn't go to Dell first...
Thx again, Ice. What a pal.
