Can you give me instructions how to open and clean CD/DVD rom and whose company`s is good and on which kind of shop it is available and how much it cost because i live in Ajmer. What do you mean by "Replace the cover and tray"? Did i have to replace with new one
Ok
1. First it looks like it will be very hard for you to open the CD/DVD drive.
Step a: Unscrew the CD Drive from your computer case.
Step b: Unscrew tiny screws from the back of the CD DRIVE.
Step c: Take a PIN and put it inside the front bezel ( there you will find a small hole near the EJECT Button. Put the PIN inside it to open the tray.)
Step d: Now remove the cover gently and the push the bezel(plastic cover) out.
Step e: Now, you can see the inside parts of the DRIVE.
Step f: Just take a clean cotton cloth and apply some Camera Lens Cleaning Liquid on the cloth itself and gently rub your DRIVE's Lens.
Step g: That's it. You are done.
Step h: Now put back the DRIVE cover and the bezel and slide the tray inside.
Step i : Screw the Cover and then Screw the DRIVE itself to your computer CASE.
Step j : Make the connections and start your computer.
2. I am not quite familiar with Ajmer. Its been a hell lot of years (10 years approx.) I went there. So, can't help you locate any store. But I guess many things might have changed by know. I used to stay in Vaishali Nagar ! Is it still there ?
3. 'Replace the cover and tray' means you should fit it back. (No need of any new tray, btw, you will not get the tray in the market as spare parts.)
