I have a Matshita UJ-840D drive in my Acer 4102WLMi laptop. As it lay unused for a couple of months there was a dust build-up on the lens and instead of using one of the easily available CD-lens cleaning solutions I decided to clean the lens with a swab of cotton dipped in some after-shave. Bad idea, ever since then the laptop refuses to read any CD/DVD.
Since my MBR is broken I have been trying bootable CD’s in order to install a new operating system, to no avail. The drive simply refuses to read anything thrown it, the rails on it seem to be working fine since I manually reset the position the lens to the end of the drive and it seems to set itself to the proper position everytime a cd is inserted. Any ideas on cleaning the drive lens? I can’t use one of those lesn cleaning CD’s available in the market since like I mentioned earlier my system gets stuck at the OS selection option.
