laptop dvd writer problem.

hello, i have a problem, my laptop dvd writer cannot open properly when i push the open button, the light also not there, what is the problem there??

I can only think of 2 possibles here, power is one, but I'd expect other things to be playing up as well, such as fans being erratic or failing to spin and the like, but the more likely cause is mechanical failure, basically you need a new drive, the quickest way to prove this is if you have another drive to swap in for testing purposes, if you do and that works fine then it's as simple as buying a new drive, they are so cheap these days it's not a major thing, of course if the system happens to be under any kind of warranty\guarantee period, then do NOT touch it, just ring them first or you may invalidate any cover you have on it. There are a couple of quick things to try, but I have little hope of them helping, but here goes, click on Start - My Computer, you will then see your drives listed, right click on your optical drive and select Eject, if the drive opens normally then further investigation is needed, if it does the same as it's currently doing then that supports my suspicion of mechanical failure. Next click on Start - Control Panel - System, a new window will open, in this click on the Hardware tab at the top, then click Device Manager, this will open another window that will list all your hardware, near the top of the list you should see an entry to do with CD\DVD drives, expand this by clicking on the + to the left of it, and it will list all your optical drives, right click on the problem drive and select Uninstall, confirm\accept everything that follows, at the end it will probably say it needs to reboot to finish this, thats fine say yes, if it doesn't then reboot manually. When you get to desktop again you will get a found new hardware\device wizard come up asking about installing the drive again, just say yes and allow it to automatically install the drive, once complete try to use the drive again, if after all this nothing changes then it's new drive time, the gears in the drive have probably broke, or worn down to the point they can't open the drawer anymore, or maybe being forced out of alignment, this can happen if you forcibly push the drawer in, using the button is the safest way to close the drawer, but it's not always the most convenient way as the button can get obstructed when the drawer is open, hope this helps anyway. *edit Just realised you said laptop, so it's not quite as simple as swapping another drive to test, and depending if you feel comfortable partially opening the system by removing the rear panels or whatever it takes to access the release screw for the drive, you may feel more comfortable taking it to a repair place to do, they aren't always difficult to do, but it may be more than some are comfortable with. But being a laptop means power may be a higher possibility, more so if the unit has been dropped\knocked, because it may of loosened the connection(s) inside to the drive, but again this may be above your comfort zone to check, in which case a repair place is your best bet, but if you wish to try yourself let us know the make\model of the unit and we can look at the manual and gauge how tricky it may be.
