Follow this procedure to troubleshoot if the TV does not respond to the supplied remote control.

1. Remove the batteries from the remote control.
2. Press each button on the remote control twice.
3. Make sure none of the remote control buttons are jammed.
4. Install fresh batteries into the remote control. IMPORTANT: Make sure the batteries are inserted in the (+ and -) direction shown inside the battery compartment.

HP is pretty good about cataloging their products and all related drivers. Thing with this model laptop is there are many variations. You'll want to go to www.hp.com and click the support tab. Use the product search box and key in the part number as opposed to the model number. The part number is on the serial tag stampted to bottom of laptop. It will read p/n and a series of letters and numbers. Key this in to the search box.This should return a table with drivers and software for your specific laptop. Note, the IR may only work when certain software is loaded like Window Media Center or media players.

you can turn off the IR on the laptop or put black tape over it!

Hold down the “DVD Menu” button and the “1” key at the same time for 5 seconds (or the "2", "3" or "4" key if you want to have the remote broadcast on one of the other supported channels instead. After 5 seconds, the LED on the IR receiver should blink twice, and your remote should work correctly again.

It appeared you might need to down the newer version of the driver.
