there should be a funtion key by ctrl and the start menu button and the f keys ect f1 f2 should show a pic of a touchpad try keeping hold of the fn button and presing that button and yout touchpad should work

No. The bulb is good. It could be the DC/DC invertor - that little curcuit board just beneath the in the LCD - or the video off the notebooks motherboard. - personal experiance points to that invertor

reinstall you display driver

Hi,

Welcome to Fixya. if you have issues with your internal microphone on your laptop you can follow the troubleshooting guide on how to fix it.

Directly from Hp website:

Resolving Microphone Problem

Drivers for Hp Pavilion Dv4000

Make sure that the driver is already installed so that it will be detected by your computer.

Thanks for using Fixya.

Does it feel like it's overheating? Does it happen randomly?

Check the manufacturer information on the bottom of the AC Adapter. Most likely the INPUT will be
AC110~240V / 50~60Hz which means that you can use it on 220V as it is within the INPUT voltage range. The AC line frequency can be from 50 Hz to 60 Hz. You will need an adapter for the AC plug itself to go from the flat prongs used in North America to the round ones used in Asia/Europe. Also, the adapter will be needed as the wall socket likely will not accommodate the round ground prong that is present on the original three-pronged AC plug that is used for North America.

~To download the manufacturers and therefore correct drivers or specific software;

Always get your drivers from the manufacturer of your Laptop, Notebook or Desktop.

If you were to log on to the manufacturer's web site, usually one is able to download if available, by model number, All available Driver downloads as required.

If the driver is not available, perhaps your manufacturer does not support the OS you are installing.

This is the best way of ensuring up to date drivers for your system and they are free of charge!

There are no XP drivers to be found with Microsoft as XP is no longer supported.

Some manufacturers may have a limited number of Drivers still listed.

I hope this helps.

Please try pressing Fn + Num lock, this should deactivate numeric keypad (Num lock indicator should turn off).

Go into the device manager and see if the driver is enabled. control panel/ system/ hardware tab/device manager/pointing devices, and see if the driver is loaded. If it is try update driver.

meaning that you had it one day and the next the BT device is no longer listed in the device manager.

I had a similar issue with a pavilion tx1000. In that case it was the wifi that would disappear. The short version is that if you are still under warranty hp will probably replace the BT card while refusing to acknowledge that fundamental design flaws in both the TX and DV lines results in a pc that will likely fail within 1 year of the end of its warranty. (google your model and complaints, or the word recalled, I would start backing up anything you consider important that you have on that machine b/c the downward cycle has begun.

Hi below are the download links : www.hp.com/cposupport/eschome.html
www.opendrivers.com/.../notebook-hp-free-driver-download.html

remove your battery and return after 1 minute. and turn it on. same problem check your memory ram.

install the original driver.

The problem is due to the GMCH chipset which is used as the vedio controller. I am regretfully say that you have nothing to do unless you are a laptop technician. Nothing is to change yourself inside the system. The chip is fitted on the motherboard itself. It needs special kind of tools such as SMD Rework Station and experience to replace or repair the chip.The service charges varies according to location, service shops and persons. Contact a technician nearby you. Make a reply for this.
