Laptop screen has gone blank

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

right click on task bar and check the customize

try looking it under a light or in the sun if you can make out the screen but the light is out then you either have a bad back light or inverter

Have this check to your nearest brand service center. There might be problems on the video card. This might be due to excessive heat that is frying the parts of the laptop. This is a common problem for Toshiba laptops. Kindly check the exhaust if there is a clogging dirt, this is the main reason of excessive heating aside from the prolong use of your laptop. My best advise is go to the nearest service center.

upon turning the computer on keep hitting the F8 key and see if a repair screen appears. If not the hard drive is gone or the disply is at fault

It seems like the lcd back light may have failed can you see a faint image on the screen when you look really close, try it with a torch. If you dont see even the faintest image the inverter has failed and needs to be replaced. If you look on youtube again and search for videos of replacing both the back light and the inverter it will give you some info on how to change them. Do a google search for hp spares and you will probably find what you are looking, i think the inverter is about £30 and the back light is bit cheaper. hope this helps.

sounds like your screen went out, if you need to access whats on your laptop real soon try hooking it up to a desktop monitor via rgb cavble.
