Toshiba Satellite Notebook starts with black screen

If the screen stays black it means there is an issue with BIOS. It should load before the HDD ever does. Mother board issue or monitor issue.

Have you checked your RAM, CPU and motherboard. IF not you need to check those things and verify which one works and which one is not.

Do you get the Toshiba logo? before it goes black, if that is so the hard drive is more than likely the problem, first! remove the hard drive and reseat it back in place, sometimes this will restart the hardware, if no change! have it tested.

Reseat RAM

possibly ur display chip or graphic chip faulty. repair it from laptop repair prof.

Hello there:
i would suggest using a spare monitor and connect the cord that would normally go into a computer and connect it to the laptop and then plug in the power cord for the monitor and turn on the computer if this works and everything is ok then you know that the laptop screen may be faulty or there may be a loose connection somewhere ok?
best regards michael

This sounds like a hard drive is, or has failed. Either that or the RAM (memory has gone bad)
Did you let the laptop overheat? Was it left on for a long time? Or is this just an old machine ?
I would replace the hard drive, and reload the operating system, that is if you really want to keep the laptop. If that solves it great! Also, did you notice if there are any "beep" noises, or error messages when it acts up? Often times, you can go on the internet and find out what the messages mean.

Hi
did you updated the bios before this problem ?
do you hear any beep ?
did you add a new hardwarw to your laptop?
answers for this will help to solving this isue

have u tried to power up with external monitor? reply back.

Try pressing FN/F5 keys simultaneously, or the key that toggles internal/external Display. Look for the double screen Icons on the keys.

Tap the Pause Key.

Restart and press and hold F8 key when Toshiba logo appears. When the boot Menu appears, select Last Known Good Configuration.

If all else fails ther should be a reset button on the side of the LT. Consult owners Manual for location
