Hello.
Okay, i had a problem with my Asus A9RP. It cant power on when i press the on button. No led lights, the fan does not spin.
At times when i connect the power cable adpter, the hdd spins atomatically without me pressing the power on button then nothing happens. All the led lights are not working.
I tried removing the battery then try booting it up but no changes. i even try reset it by removing battery and power cable then press & holding the on button for 1 min nothing happens.
The part i'm confuse with is the led lights. all dead. no battery light charging indicator, hdd light, power. all lights are dead even when random times i can hear the hdd spins as i've mention earlier.
can any one help?

Take DC voltmeter and make sure the adapter is putting out the proper voltage.  The correct voltage will be found on the adapter, it is the secondary voltage figure.

 

Make sure that the adapter plug is not loose.

 

How old is the battery?

well my laptop is a bit old, 4 year old. the battery is that much old since it comes with it i guess.
i've tried testing the adapter with a voltmeter and it reads 15vlts which matches the secondary value on my laptop adapter.
I've also tried testing the cable adapter with another laptop(using the same adapter as mine) and it works just fine.

If this is the original power adapter I would say that you are good to go.  

 

If this isn't the original power adapter please post the amperage figure on the adapter.
