Fix a HP Pavilion dv6000 with no sound

If your dv6000 has suddenly developed a no sound issue, follow the following steps to get your machine back up and running.

The issue could be a couple of things

1. The driver could require reinstalling. (Avaibile from the HP website)
2. Or more than likely could require a new power button board and cable

This is a commons issue on this range of laptops. The power board is connected to the motherboard via a ribbon. These boards are prone to breaking and simply need replacing to fix the issue. (The speakers are connected to the power button board)

Try an eBay search for 'dv6000 power button board' and install it. This works 99% of the time and is literally a two minute fix.

To install:

• Reove the silver screw that are under the battery cover.
  
• Remove all keyboard screws from the base (there are 3 keyboard screws in the battery cover also)
• Carefully prise off the strip cover (the cover that the power button is in.
• Remove the keyboard
• Install the new power button board
• Fix that laptop back together!

There should now be sound on the machine when windows loads.

Good luck!

How to find the part number for a HP laptop motherboard

If you have a HP or Compaq laptop, more than likely the motherboard has failed or is about to fail!

To find the part number of the motherboard, so you can replace the defective one:

1. Remove the RAM cover on the laptop
2. Remove the RAM from the holders
3. That's it. The part number or P/N will be listed. For example 454883-001 (Sometimes the part number is listed as SPS: 454883-001 however the same rule applies)
   

Now its possibe to find replacement parts for that specific model by typing this part number into google or even eBay.

HP Pavilion TX1000 no boot issue - Oven fix!

Do you have a HP Pavilion tx1000 laptop with a no post issue?
If you get the symptons, boots up (blue lights activate) but no image on the screen, this may be the solution!

1. Start by stripping the machine down. Take all the covers off the bottom of the machine and remove the hard drive, memory and all screws from the base.
2. Remove the LCD digitiser and the other connectors from the motherboard.
   
3. Remove the keyboard by genlty prising it out.
4. You can now access the screws holding the LCD module on. Remove these and the swivel unit should now be free.
5. Remove further screws from the keyboard area and the top cover should now gently prise off (remember to disconnect all wires from the area)
6. The motherboard should now be accessible and come free when the powerbutton and all other connected PCB's are removed.
7. When the board is free, remove the heatsink/fan, bluetooth module (if installed) and CPU.
8. Remove all 'meltable' items from the board (such as the foam LED covers for caps lock and power indicators)

Right, now for the strange part!

The no post issue is common problem for most of the HP DV range. The VGA chip on the board becomes defective.

The way i fixed this TX1000 was to 'reflow' the VGA chip using a conventional oven (excuse the pun).

Place the motherboard (minus the plastic attributes) on a baking tray and place in an oven for 6-7 minutes then turning the board over, for another 6-7 minutes.

When the board has cooled down, carefully reassemble the machine (not forgetting the plastic shields). If all has gone well, the unit should power up and actually post!

Please post comments on whether this worked for you, hopefully, you've just saved a few pennies!
