Toshiba Satellite screen unresponsive after Factory reset?

August 25, 2015 at 12:43:42
Specs: Windows 10
I own a Toshiba Satellite U945-S4110. It runs Windows 10 in case that matters.

My computer had a lot of word documents and files, and I wished to use it for school, so I did a factory reset to clean it out. After it finished the reset, it restarted on its own. Upon booting back up, the computer appeared to turn on without issue, except the screen which now does not even flicker or do anything at all.

I have tried resetting the computer, held down the power button for 60 seconds, attempted to brighten the screen via the keyboard. Nothing has had an effect upon it. The lights come on that should when powered on, including the charge light if I plug in the charger. And you can feel the slight vibrations of the fan(s) inside the computer when powered on.

Everything appears normal except the screen, and it has never done this before.

Any help would be appreciated. The majority of my class is digital including my textbook and worksheets even though its an in-person class.

Thanks in advance,
Tmanning

Factory restore was a rather big gun to use. However, if you "never ever" see "anything at all" on the screen it is most likely a hardware fault. What you did might have been a coincidence. The best first step is to try an external monitor on it to see if that works. We can then suggest the most appropriate next step.

Always pop back and let us know the outcome - thanks

Ok I have not tried that, but I do have a hdmi cord. As you put it, I never ever see anything on screen. I will try this and see if it shows anything.

Its like using an elephant gun to go after a mouse or using a sledge hammer to hang a picture, maybe getting in a Maserati, jumping on the highway for one short exit to purchase a container of milk.
It would have been easier to open your Documents folder, select all, and delete them. Or if the drive is large enough, just copy/paste them into another archive folder and they will be available if you ever need them again.
I gather that since you had Windows 10 and did a factory restore, it came with Windows 10 so it could not have been a very old machine, How could you have collected that much junk that you needed to clean it out already? Windows 10 has been out just under a month... It is sounding almost like this is a stolen laptop and you were trying to hide this fact by wiping it clean to keep it or sell it...

You have to be a little bit crazy to keep you from going insane.

It's maybe a year or two old, bought at walmart. It has 10 due to getting the free download to upgrade from 8 that I received in my email prior to 10 being released. And yea I probably did jump the gun on the factory reset to begin with. I've done it on my phone 2-3 times and thought it wasn't as big a process as it is on my computer. I'm at work for another hr, I will check the hdmi cable when I'm home.

I saved all my files before hand on an external hardrive. My laptop has 500gb hard drive and was half full with files, movies and steam games I've purchased.

At least you were wise enuff to safeguard (as in duplicate/copy) all your files to external storage. Thus any rebuild routine won't lose those...

Incidentally if when you bought it it had a recovery partition (still there) then the factory reset "ought" to have reset it back to the OS (win-8x) in the recovery partition?

So I tried plugging it into a different monitor/tv with an hdmi and it didn't even register on the alternate screen that the computer was plugged in.

I attempted the battery route with taking battery out and resetting power using the charge cord.

And tried using the Shift/f8/power reset function.

I also tried pressing everything together as round the screen and the keyboard to ensure nothing was loose.

So far I have had absolutely no progress. But the laptop does turn on still. Screen still does not lighten or anything period.

As far as the partition, I admit I'm not overly familiar with how they work, though I've heard a little about them. :/

I'm wondering if the factory restore would have given you back windows 8 or if the upgrade to 10 also upgraded the restore partition. Or could the upgrade have caused the restore to fail? Some info here:

http://www.daytondailynews.com/news...

No logo or posting screen either? It does sound like a hardware failure. Try tapping the bios setup key or hitting the PAUSE key--anything that stops the boot process.

Yea the screen stays black completely, there is no sound and no back light period when turned on. Only the slight vibrations of the computer and power light, as well as charging light, to show I turned it on.

I will try the pause option; which key is considered the bios setup key? That is new to me.

Apparently for that model you hold down F2 while turning on the laptop.

I slightly edited my # 7. You might have another look at it.

Download the Windows 10 ISO image on another computer, burn a DVD with it and reinstall Windows 10 from that. Here is a link:

I tried the f2 option and it "appeared" to have no effect.

As far as a disc, mine has no disc drive to put a disc in. It's a slim ultrabook.

You can use a USB Flash Drive instead - see the link.

It's difficult however to set the flash drive ahead of the main HDD if you can't see anything on the screen. I'm inclined to think this is a hardware fault and the factory reset was nothing to do with it - coincidence. Maybe the display module or some poor connection in that area.

Always pop back and let us know the outcome - thanks

It is possible that the issue was hardware related but also now that the factory restore was started, there is no complete operating system so it will be more difficult to determine.
USB Flash Drive install should work as long as system is sound. A USB external DVD drive is not that expensive and may be worth the investment.
You can also create a Live Linux Disk (DVD or Flash Drive) that you can try to boot the system to which will also confirm if the hardware is in operating condition before trying to reinstall Windows (Boot from the disk and check out the hard drive, memory, etc.).

Ok I have a 32gb flash drive. If that route does not work, I will aquire an external dvd drive and attempt this as well. Thanks for the input/ideas.

So far nothing has worked on my end. I'm wondering if sending it in to toshiba is only way? There is no warranty as it expired ironically before this. Of course. Hmm.

Have you tried the Linux variant approach - a ubuntu DVD boot?

If it won't boot via that then there is likely an issue with hardware? Presuming you do have a DVD unit installed, and that the system is set to boot from it.

If no built-in DVD unit, does the bios allow an external usb device boot?

If so then one can also boot into ubuntu from a flash drive.

This link describes how to make one:

Black Friday, as the day after last Thanksgiving? Seems like a warranty should be longer than that.

You recently did the windows 10 upgrade and then today you have the problem. How much time elapsed between the upgrade and the problem?

Of those experiencing problems with the upgrade most at least get something on the screen:

http://www.tomshardware.com/forum/i...

http://www.siliconbeat.com/2015/08/...

So depending on the elapsed time between the upgrade and the problem starting, in your case it may be coincidental.

Also check the link in my # 7 above.
