Having problems with your HP PC Laptops ?

Backlight not working on my hp laptop - HP PC Laptops


Answers :

To generalize this problem is not recommended.
\015\012Usually this happens on laptops with a display lighted up by a CFL lamp (some units have a two CFL lamp display).
\015\012The first recommendation is to test if the inverter is working properly. If not, just replace it.
\015\012If the inverter is ok, then the lamp on your display is damaged.
\015\012You can replace it using a lamp form a used display or replace the display. Lamps are not sold separately and the process to obtain it from a used display is complicated so we recommend to replace the display when the inverter is ok.
\015\012The part number for any on these items can be found on www.hp.com with your model number which can be found on the back of the unit.
\015\012Hope this information may be useful.
The wires between the display and the mainboard are cut or the inventerboard is bad, or the backlight is fried.

this will require you to open up the laptop, if you don't have any experience you should take it to a local professional or shop.
