3. Checked RAM= OK

4. Checked HDD= OK (took backup)

    Its Not showing anything on external display either...

    But I am not too sure about whether Processor is working or not, cause cant check fan working or not

    Hmmm., if u said that fan is not working it might be the motherboard issue., cause fan is connected with motherboard., as you said no display., power blinks., Fan not working., Extreme most possibly be mother board Issue., cause if it is processor at least it will make some noise or fan will surely work.,.,
  5. Hi Guys, i m Ashok, i m using Studio 1555 since Aug 2009. Windows 7.

    5 days ago i faced same issue, got it repaired today, the graphics chip was damaged, repairing guy recalled the chip with some machine and it worked, system is running like new one. get your laptop repaired by someone who repairs on chip level. Reason behind this graphics chip damage was RAM, it was repeating this problem with chip after getting flashed 2-3 times, then the repair guy also changed the RAM. Now its working fine. Hope i'll use this laptop for long with less repair in future.
