How old is the battery. It may not be holding a charge because it is so old. Try holding down F12 during boot up to see if it offers you a battery recalibration option. If it does, follow the on screen instructions to the letter. Best of luck
Open the RAM lid ( at the bottom laptop ) use a small screw driver (+) removes the RAM memory module ( right and left at the same time ) Clean it up with a dry tissue or a white paper > specially the connector. put it back on and you can try to turn it on
Try lowering your display settings when it is hooked up to the external monitor. Then try the laptop screen again.
Right click an open area of the desktop, select properties, click the display tab. In the lower left of the box there is a settings slider, try lowering the settings and see if it gets better.
I have had this same problem with a HP DV2000 and the
problem is not the contrast light. What it is, is that the laptop
thinks that the screen is been shut down that is why the light does not
come on. The best way to solve this is to remove your keyboard first.
can remove the keyboard by removing exactly 7 screws from your laptop
back, there are 5 screws located under your battery and other two that
are in the location of your RAM'S.
Just open them up and then
you will notice that the key board pops out abit then just simply take
it up and then just below the keyboard, on the same line where HP brand
logo is on your machine there are two small clip types of pind, that
you can remove and put back. There is a clip that is hidden abit
under the metal plate, so just try and remove that clip from its place
using a needle or any long and thin object.
That will make the
laptop not have the problem. But once you remove that the laptop
constantly will think that the screen is open even if you close it.
then after like a week or two you can put it back and all shall be fine
if not then just remove it and keep it out.
You can then set
your power options to shut down the screen light every 2 minutes or
something like that so as to avoid the backlight being switched on all
Yes, this is a defective screen. The only fix is to replace the screen. It's called a column of dead pixels. Since it is under warranty, contact HP to have them warranty it out or take it back to the place you purchased it from for an exchange. Please take a moment and give this answer a good rating of fixya. Thank you.
