Question about Compaq Presario V4000 Notebook PC
I ave no sound because the volume decreasing button stays convex instead of concave. Do I have to pop the entire top including keyboard off?
Does the machine have regular keys (that remove) or a "blister switch" type key pad? Have you tried to use compressed air to remove any obstruction? OR try to pry the key, very gently, up? A LITTLE silicon spray? You may have to remove the keyboard. If you use the Tray Notification Area Sound Icon to increase volume what happens?

I had the same problem, they are very easy to fix, I did a search earliar and found some on the link below.
You do not need to dismantle to base, you have some star screws under the battary and one either side that loosens the small panel near the screen (where the power button is). The screen cover has screws under the plastic covers then just unclips, be gentle. after that it is self evident

I had a Hp or compaq tablet *with swivel screen. I have a hard time myself trying to get it to beam up. what a pesky switch. But I do know what happened to it before it started acting bad.... the spot where I plug in the power cord got extremely loose.. and i had to hold it just so with one leg of mine in the air one under me.. :D joke but you get the point. Just to try to get it to charge up. I didnt know if it was just the plug... I found out later with the help of a charging dock. That it was in fact the chargeing hole... After about 5 hrs playing with the cord in the charge dock to get it just right. It charged up for a measly hr or so. But since then when I use the charge dock the laptop will boot up...

For unknown reasons, only the computer gods know what happened. You need a new system board for your laptop. You can buy one and fix yourself or have a computer shop replace it. Your probably better off buying one off the internet and take it somewhere to have them replace it.
I found a brand spankin new one for you on ebay. http://cgi.ebay.com/New-Compaq-Presario-V4000-915GM-System-Board-383463-001_W0QQitemZ170158400649QQcmdZViewItem
