I am having a problem in starting my laptop when i press the start button its show light in processing and cd/dvd rom but then suddenly light gone and it wont start...... please help me as early as possible
How do you get power to your laptop - via power cable or via battery?If you plug the charger into the jack, can you see the light blinking or just everything remains calm and nothing can be heard from the fan or the hard drive?
If you can't and the warranty of your laptop has expired I suggest you to take out the hard drive and try to connect it to another computer through SATA-USB cable. If the HDD doesn't spin at all, anywhere, then it has failed mechanically and needs replacement.
If your hard drive spins up on a different computer and it is recognized there, but cannot power up on your laptop, then the problem is hiding probably in the power supply unit on your motherboard. You could bring your laptop to a technician to make a test of the power connector and/or the power jack center because they might have got damaged.
Once you have done all of the above, please come here and share the results.
