Aspire 5551

 

Pressing the power button spins the fan for about 5 seconds and stops.

 

No other response.

 

Power light is on.

Battery charges.

 

I have reset the ram and used just one chip at a time.

 

I have connected the disk to another computer and scanned. Fine condition.

 

any ideas?

    Unplug the external devices, Unplug the charger, Remove the battery from the laptop, Press an hold the power button for 30seconds, After 30seconds connect the battery and the adapter, Try to check whether the laptop is booting.

    Hello johnson35,

     

    When you start up your laptop, do you hear beeps?

    Do you see the acer logo on the screen or a blank screen.

    The fan spins and stops and NOTHING else happens.

     

    I have disassembled the laptop. Got it down to bare minimum. Same result.

     

    So it figger it is either the MB is bad, with only the power part working.

     

    Or the CPU is bad.

     

    Other thoughts?

    Hello johnson35,

     

    1- Have you performed a Clear Cmos in removing the RTC battery?

    2- Have you checked the output voltage of the AC adapter?

    Thank you fo your response.

     

    The power supply is providing just over 19 volts as it should.

     

    The battery is soldered to the board.

     

    I did do the "hold power button for 30+ seconds without battery and power supply."

    "The battery is soldered to the board." Grrr!

     

    Have you cleaned the DC-IN connector with a contact cleaner spray?
