Hi Bery Mngoya,

Try the below mentioned steps and check if there is any change:

1. Take technician's help or by yourself remove the following components from the computer and then power on:

a. Memory Module
b. WLAN Module
c. WWAN Module
d. Hard Drive
e. Optical Drive
f. Keyboard

You can find steps on how to remove these components from the Service Manual of HP Pavilion dv6000 Notebook PC (http://h10032.www1.hp.com/ctg/Manual/c01035677.pdf).

Note: Perform the above step only if you are comfortable working with the internal components of your computer. Otherwise, it is always advisable to take a technician's help. Please go through the "Preliminaries replacement requirements" section of the manual before opening the chassis.

2. If the computer powers on and stays on with these components removed. Try connecting these components one at a time each and try to power on. This will help you identify as to what component is causing the problem.
3. After isolating replace the faulty component.

Do reply with results.

Thanks & Regards

Hi Bery Mngoya,

I am sure you have tried a different AC adapter if the AC adapter has no sign of power. Also, you have tried a different wall outlet to ensure there is no failure in the initial power subsystem? Trying a different AC Adapter without the battery will also be a good idea. If this all fails then I would recommend referring to the service manual page number 2-21 and take an HP technician's advice to replace the parts accordingly.

Please reply if you have any further questions.
