Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. When you press the power button, the power button lights on, but then it will immediately turn back off?
Please let me know by replying to me here so that I can help you further.
Thank you for writing back with that information.
Have you tried to hard reset the laptop?
First, please do the following Hard Reset procedures to revive your frozen laptop. This will revive your laptop if there are no hardware related issues, like the motherboard.
Here are the steps, please do them IN the order they are given:
Please let me know your results so that I can help you further.
Did you follow the procedures I gave you? Did you do it with the laptop connected directly to the power adapter WITHOUT the battery?
Thank you for writing back.
Unfortunately, since the laptop was not revived using the hard reset procedures that I gave you, I believe this is already a hardware failure or malfunction. The main problem in this scenario is a faulty motherboard or a grounded or broken power slot -- the small hole where you insert the power adapter jack.
So I highly recommend sending or bringing the laptop to the nearest Toshiba service center for further hardware diagnostics and replacement of the failing part.
I believe this is not the answer you wish to get and I hate to be the bearer of this bad news. But it will be unprofessional of me and unfair to you if I will not provide the answer no matter how bad news it may appear. At least I save you some time.
