You could have a faulty inverter but
You most likely have a defective CCFL backlight, it may have the following symptom:

• Screen flashs on red/pink and off.
• Picture stays on in red and slowly be come normal.
• Picture flickering with dim display.
• Picture flickering on and off.

All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

that means your laptop has no power so your battery is dead which would explain why it shut down on you, and that means its not charging so it would either be the adapter or the port on your laptop

Hi, Actually, the problem here is you don?t have any options in windows XP to increase the brightness without using keyboard. HP does not provide any utility with the OS as it is OEM. Try this · Click on start > Click on control panel..... · Click on power options.... · Click on " Change settings plan "..... · Adjust the brightness and save the plan..... And exit... that should work.... OR Replace the keyboard and get the all things working
