If you want to reset the BIOS password remove the computers battery and then open the backpanel and remove the bios battery for about 20sec. If you want to reset Windows admin password this is harder issue -> easy way make a backup and reinstall windows and then restore the backup.

SOURCE: How do I disable double-click on an HP Pavilion dv4 touchpad?

Hi there Dublin. I recently bought a HP laptop myself, and I believe I can help your situation, or at least I hope I can. Here's what you do: Access your Control Panel>Click Mouse>Click Device Settings>Click Settings> Click Tapping> Click Disable Tapping. That should do the trick. You are not disabling your touch-pad, just the double-clicking that is associated with it. Drove me nuts for about a day, 'til I figured it out..Hope it worked for your notebook.

SOURCE: HP Pavilion dv4 not turning on

Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes P
c

More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.

Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

SOURCE: hp pavilion dv4-1220us overheating then shutsdown

Sounds like you need to take it in for repairs, clean outs and/or replacements.

This product is known for it's heating issue and power consumption. Maybe the fan is starting to wear out and it's affecting the rest of the system. I would suggest checking the warranty on the system, if it is no longer valid, then I would look for a local tech in the newspaper.

SOURCE: i have hp dv4-1465dx, how to reset bios without having OS

Hello,

Was Windows 7 the operating system that came with

your System? If not, What I would advise you to do

is this:

Check HP website to find out if your Laptop supports

Windows 7.

If it doesn't, then I would advise you to

PLEASE change it back to the operating system

that came with your system, or better still, the

operating system that it supports.

The reason is because that is exactly what I faced

two weeks ago....

I changed the operating system for my PC to

Windows 7 ( Even though it doesn't support it)...it

worked fine for a while, then later it started to develop

faults after a while...like stuttering, mouse pointer

moving round the screen, graphics displaying

improperly...etc.

I first thought it wasn't a big deal, so I fixed it by

repairing the drivers, and it worked fine once again...

After using that same crack that you said you used,

I started getting "Multiple Hardware Error"!

It would just Power on, Show HP Logo, Show

Wireless LAN indicator Led ON, and It will freeze

there. I could not even enter the BIOS.

In short ....Now as I'm typing, the system is

with HP Service Centre for they have to change the

Mainboard Outrightly!

So PLEASE, if your system was not specified

Windows 7, use the Operating Systems that it

supports.

Then go to HP Website and download the original

BIOS settngs for your Laptop then repair your

system with it.

But if it is the one that came with it, then let me know

so as to tell you some quick fixes.

Hope this helps you out.

Goodluck and thanks for using fixya!

Blue screen on envy 13 admin password prompt with system disabled - CAN YOU FIX HP ERROR CODE 64449838


I can only help with the system admin password (presumed windows). You will have to manufacture a "Password Reset Disk" on another PC or laptop (preferably running same OS - you will need your product key COA number). Instructions on MS website. Also - check your BIOS settings are OK when setting to boot on the password reset disk. That will be F1 or DEL probably on power up.Good Luck.

How do i get the sound on my HP Pavilion laptop to work again?


Well, you need to make sure its not on mute. If its not, then try reinstalling sound drivers. IF this doesn't work, then its probably broken.
