While I was using my laptop it went off and afterwards, when I press the power button while connected to the power adapter, the laptop gives 3, 4, 5 and 7 beeps randomly and does not on.
Also the power adapter indicator is on but the Laptop power indicator and charging indicators are off.
I tried removing the battery and also cleaned the RAM.
Model: Dell studio 1555
Please, can anyone help me with this issue.
The common thread is that all of these point to a bad mainboard - that's the faulty part.
