The laptop was working fine yesterday. Today when i turned it on:- -the power button turns on -the three support buttons on the top right corner of the laptop flash -i can see battery and power notification lights but the hard drive light doesn’t blink or turn on -i can hear and in fact glimpse the fan working, after 5 seconds, fan stopped -the screen shows nothing, it isn’t a black screen because that would imply that the screen still turns on but the screen remains off. -I hear beep sound after 2 minutes. Following methods i tried, but still same problem:

  1. Removed the battery and press the power button for 30 seconds to remove static current, after that tried driecctly using adapter without battery.
  2. Tried holding down the Fn+d and press the start button OR hoding down the D button and press te start button.
  3. Alsi i removed the RAM adn reinserted, still same
  4. searched some where to check whether the mother board is working or not - i tried this - “Removed the memory modules from the laptop and turned on , i heard the beep sound that means says that the motherboard is working fine. Please help me on this. Thank you.

Hi @siva5110 , According to the specifications there are two RAM slots in the laptop. Try the following: Ensure that you disconnect the power and the battery from the laptop when you go to remove/insert the RAM modules. Here’s a link to the service manual for your laptop. Scroll to p.19 to view the procedures to remove/insert the RAM module. If you only have 1 RAM module inserted, try moving it to the other slot and check if the laptop turns on. Basically you are testing if the RAM module will work in either slot. if it doesn’t you’ll have to get another compatible RAM module and test if the laptop turns on as the original RAM module may be faulty If you have 2 RAM modules inserted, remove one and then try to start the laptop. If no good move the RAM to the other slot and try again. If still no good, remove the RAM module and insert the other RAM module in the first slot and turn on the laptop If no good move the RAM module to the 2nd slot and try again. Basically you are testing if either RAM module will work in either slot. If neither module works in either slot try another compatible RAM module and check if the laptop turns on. Although it would be unusual for 2 modules to fail at the same time. If the new RAM module also fails in either slot then you have a memory controller problem on the motherboard.
