Black spots laptop screen


Pinpointed spots can be damaged pixels that no longer light up when energized. They cannot be repaired and you will have to live with them, or get a new display. Try to use the Color Adapter port to a standard LCD Screen. On the side of the computer is a small 9 pin (usually blue) port whereby you can attach a desktop monitor as an alternative to the LCD Panel on the laptop.

I find very hard to open my dell optiplex Gx240 computer case(formfactor)model number:DHM,serial number:FKDLC11,fcc class:B.Please i want to also change the language of the very pc from french to...


You must push both buttons on the top and bottom of the case all the way in, and then the case will open up like a **** shell. It can be very stiff from the hinge and all the wires.
If you perform a repair install with the Windows XP cd, it should allow you to switch to the English version as it asks you what region/language you want to use during setup. But you should be able to switch to English via the Language bar or the Regional and Language Options Control Panel.
