Can anyone please help/advice. I have a Dell Inspiron M5040 laptop. When turning power on it gives 3 short beebs (then silent for 5 seconds before restarting 3 short beeps again). I have taken the battery out and put the battery back in and occasionally this works and the laptop will boot up and start but this only happens ever now again. Have done a system restore for the month before when it was all working fine and this problem still happens. Done a full scan system diagnonsis on dell site and it says everything passed so am at a loss what to do next. Any advice would be gratefully appreciated. thank you
