Just repaired a similar problem on a GX110. There was a ribbon cable to the effects board that the IDC connection was poor... move the cable and loud crackle. If you open the unit look for a ribbon cable about 1.5 inches wide going to a squarish shaped board. Wiggle it and if noise is there, squeeze the cover on the cable at the board end which is a fixed (doesn't come off) soldered in termination. Wiggle it and warm with a hair dryer to get wires seated.

You can go check at RadioShack or order the ribbon cable from EBay - http://cgi.ebay.com/HP-DV6000-DV9000-E220709-E118077-Power-Ribbon-Cable-/300393384553?pt=LH_DefaultDomain_0&hash=item45f0d74a69#ht_500wt_951

The keyboard connector come in two types.
A plastic connector and usually has a plastic tab that you pull to lift the connector off, DO NOT PULL on the ribbon cable.
The other type is, a ribbon cable that is inserted into a plastic socket on the motherboard. To release the ribbon cable, lift up the plastic catch on both ends of the to release the ribbon cable. When you want to insert the ribbon cable, make sure the catch is in the up position before you insert the ribbon cable, then insert the ribbon cable and the push the ends of the plastic catch down to lock in the ribbon cable.

The C600 keyboard connector is a ribbon cable with a push down to connect block. When one side of the keyboard keys do not work it is usually because the pins in the keyboard socket do not make a good contact with the ribbon cable.

Remove the keyboard and visually inspect the pins in the connector.
If necessary you can prise them back into the correct position using a sewing needle or something similar to get behind the pins.

Make sure you discconect the power supply and battery before you attempt.

Hi,

If you feel the power adapter working fine with the diff unit its not an issue with the adapter,

Now, if the unit is not powering on.just perform this:

Take out the batter, adapter and make the unit stand alone and press and hold the Power button with out any power to the unit(Without battery , adapter) by doing that we can take the static charge which might be causing the issue,

If that does not fix the issue, try reseating the RM if you are comfortable, here is the steps:

you may have shorted your keyboard (spillage??)

if your laptop is outside warranty you can check the connection to the keyboard, by removing the top bezel, undoing the keyboard retaining screws and then check that the ribbon cable for your keyboard is seated properly, If reseating this cable does not work the you can always order a replacement for your keyboard, you can find the part number for the keyboard you have, it should be printed on a tag on the reverse of the keyboard.

Most laptops have a couple of screws on the bottom that hold the keyboard in, and you will probably have to pop off a cover along the top of the upper cover. The old keyboard will lift out and there will be a flat ribbon cable plugged into the system board. Carefully release any locking tabs and unplug the cable, then plug the new one in and reassemble the computer.

If you search for "keyboard replacement" for your model, you should find plenty of detailed information (possibly even youtube videos) illustrating the procedure.
