Hi EEs,

I can not see any boot text & can not boot from DVD / cd.
I check : warranty also expired before 2.5 yrs back,
when i power on it screen remains black n i can not see the startup boot process at all,

Can any one advice the diagnose process to find out the prob so i should replace that particular part? like if the motherboard is broken down...i should place order for it...

Pls advice...

Hi,

When switching on the laptop do you see any power indicators coming up? There could be 3 major components that could be the cause of the problem.

1. Power Supply (Battery / Power Adapter)
   - Try connecting a known good power adapter and check if the laptop boots up.

2. LCD Display
- If you have an external monitor that you can connect to the Laptop and if you can see the display on the external monitor it could then be the Display unit.

- Try tapping the Caps Lock / Num Lock Key and check if they toggle if yes then it could be a display problem.

3. Motherboard
   - Try reseating the RAM and check if it helps.

Hello,
can you assure that the power supply is working - is there a light on the power supply?
Try removing the battery - perhaps this device (the charging mechanism) is the problem.
If power is OK, perhaps the graphics card is the problem - try an external monitor (many laptops have function keys on the keyboard to switch the graphics output to an external monitor).

Does the laptop make any noise when booting form a CD/DVD - you should hear the access to the CD/DVD.

• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS

That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen. After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.

Replace your battery.


If you check with a extern monitor like the other two have suggested if that doent work it could be
your inverter or back light

The HP DV6000 series laptops are known to have problems with bad soldering on the motherboard at the GPU.  It is possible to reflow the solder if you are the adventurous type.  Otherwise the motherboard will have to be replaced.
