Pavillion DV6700 will not start, no BIOS screen just black

HP Recommended

Pavillion DV6700 will not start, no BIOS screen just black.
I powered down the machine yesterday (Shut Down) and now this morning the computer will not boot.
When I try to boot the machine the BIOS screen does not appear, the HD light flickers on but then stays off. All other lights on the machine are on as normal. The fan kicks in within 30 seconds and sounds like it's running at maximum revs.
I did a hard reset and  reseated the HD and the RAM and replaced the RTC battery without fixing the issue.
I will disassemble the unit and make sure the fan is not clogged, in the meantime does anyone have any thoughts ?
TIA

You don't need to disassemble the laptop to check for obstructions\dust bunnies etc.

Use a can of PC compressed air at the intake and exhaust ports on the bottom of your PC to clean it.

Try removing the hard disk and pressing start. What happens?
Does the BIOS give you an error message?

You can perform the same test with RAM by using one module at a time to see if a failed RAM module is causing your notebook not to start.

Hi erico,

Thank you for your reply. I removed the HD and pressed start all the normal lights but no error message.

Similarly I did the same with both RAM modules same results but I did get 4 beeps when I removed them both..........so something is working somewhere 🙂

Do you have any other thoughts ?

TIA

Four beeps - graphics controller not functional

Three beeps - faulty RAM module

 

Take a read of this HP document. Count the LED flashes as the notebook starts (or attempts to) up.

 

Best regards,

erico

Hi erico,

There are no flashes or beeps when I try to start the machine. 

The machine just has a black screen with all the normal lights on except the HD light which as I said flashes briefly then goes off.

I only got the 4 beeps when I'd removed all the RAM and hit the start button.

I asked a mod to approve your images so I can view them.

What do the images show?

When you did the hard reset was the battery removed?

If you connect an external display to your notebook's video output port do you see any video?
