Black screen on toshiba satellite laptop. No bios

April 30, 2018 at 04:42:28
Specs: Windows 7
My wife's Toshiba Satellite c660-125 got hit with a ransom demand virus (unknown source). This resulted in a BIOS password corruption/not recognised. I managed to delete the corrupted BIOS password but now I have a Black Screen for my troubles. The laptop tries to start (light comes on at the front of the laptop, fan spins, HD spins and tries to load something) but after about ten seconds the HD stops. Fan is still running and all required lights are on. Just unable to load anything, and this might even mean the BIOS setup, as this was what first appeared to be hit. I have tried all the available "black screen remedies" (including trying an external monitor, change RAM etc) on the web but so far no luck

Does a boot disk, such as your W7 disk, boot?

AFAIK, ransomware does not attack the BIOS. Can you explain how you "managed to delete the corrupted BIOS password" because that generally is NOT a simple thing to do.

Yes riider, I agree, but sometimes it is just knowing which two jumpers to 'short'

All I can say is that the laptop worked fine before the attack. After the attack I could not even use the BIOS password to get in to remove the trouble if it could be found. The BIOS was available before the attack, BIOS was not available after the attack. I did not get the chance to go any further

I'll have to take your word for it. So you're saying you can now boot the laptop, press F2, enter the BIOS password, & then access the settings menu?

I recently had to remove ransomware from a friend's PC that was locked by a startup password. Are you seeing THIS by any chance?

To the last two replies, most appreciated by the way, I cannot access the BIOS. It is not that I cannot load Windows, I cannot access anything. It is not the Windows password that is missing, I cannot load Windows so I do not know if I have problem with Windows yet. I am trying to access the BIOS.
Thanks for the heads up on Lazesoft however. Will that enable me to reload the BIOS?
I am not yet convinced that I do not need a BIOS upgrade

This is not making any sense. If you can't access the BIOS, how do you know you deleted the "corrupt password"? Personally, I don't think the BIOS was touched by the ransomware. It doesn't work that way. Unless it was somehow tied to some other type of infection?

Try this - completely power down the laptop, unplug the power adapter, remove the battery, then press & hold the power button for at least 30 seconds. After doing that, temporarily remove the HDD. Put the battery back in place, plug in the power adapter, press & hold the F2 key, then press the power button while still holding the F2 key. Any display on the screen?

If that doesn't work, completely power down again. This time, press & hold the Esc key, power up the laptop, release the key after about 3 seconds. Anything?

Do you get any advanced boot options, BIOS Flash, etc. from the various F keys?
Is it asking for a password or are you getting nothing?
Can it boot to any external like CD/DVD or Flash Drive? Try above or even Seatools, Memtest86, Puppy Linux, etc. to see if you can get anything past the possible BIOS set up.
Is it possible that your 'Shorting' caused a corruption to the BIOS or other damage?

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

Garry,

If only the BIOS was affected, it might be possible to recover
what is on the hard drive by removing it and connecting it to
a different computer.

Aside from that possibility...

Please tell us anything you know about the ransom demand.
What it looked like, what it said, how you got it. Anything.

Was BIOS password enabled before the ransom demand?

Tell us what you can about how you disbled the password.
Did you literally short two points inside the computer, or was
that just a figure of speech?

When you power-on the computer, does ANYTHING at all
appear on the screen? Even just a flashing underline?
Does a short message appear saying which key to press
to access startup options?

You didn't answer riider's question in reply #7 asking
if you saw an input box asking for a "Startup Password". He
linked an image of the input box in the last line of post #7.
Please say whether such an input box appeared.

To Jeff, I did the 30 sec, 1 min, 3 min recovery technique but I admit I forgot to remove the hard drive. I will try again this time removing said hard drive and let you know the result.
Let me put this as plain as I can. The laptop reported that there was an attack and for a sum of money, the attacker would send a "something" to resolve the problem. The Wife immediately shut the laptop down.
Prior to the attack she could access the laptop using a BIOS password and a Windows password. After the attack, she tried to access the laptop using the BIOS password. This did not work and after three attempts, it shut down.
I tried again using the BIOS password with the same result. I then tried the hardware process whereby a BIOS password could be deleted hoping to get a bit further into the computer to see what else could be found.
On boot up now, The lights come on, the fan spins, the HD tries to boot up but NOTHING is shown on the screen.
I fear I may have done something to the BIOS I don't know.. Before I go further, I am asking if anyone out there has any idea of a next step I can take before flashing a new BIOS. I have heard rumours that the latest BIOS available is not that reliable so am reluctant. I do not know where the recovery disc is any more as the laptop is over four years old and the disc was "put somewhere safe" by said wife, and now cannot find it.
Any fresh ideas pleas?
When trying to boot the laptop now there is just a black screen. No cursor, flashing or not, nothing, just a black screen. I did nbot say that i could see a request for a BIOS password

GarryA, are you sure you sure your wife was using a BIOS password to boot to Windows, which then required a Windows password. This sounds like a hard drive password was in use.

Clearing a BIOS password on a laptop cannot be accomplished using any jumpers on the board. That would defeat the reason for the password in the first place.

The plot thickens....

"after three attempts, it shut down" - that's what it's supposed to do.

"I then tried the hardware process whereby a BIOS password could be deleted" - I don't know what this hardware process is, but I know there's a lot of methods listed in various forums & on youtube. If you shorted some pins or something in an attempt to reset the BIOS, you may have shorted the wrong pins & damaged the motherboard. Laptop manufacturers' put BIOS & HDD security measures in place for a reason & if they were easily bypassed, they'd be useless. It's usually necessary to take the laptop to an authorized repair shop.

"I am asking if anyone out there has any idea of a next step I can take before flashing a new BIOS"

How are you going to flash the BIOS if the laptop won't boot? Take the HDD out to see if the infected drive is what's stuffing things up.

I don't know enough about this kind of problem to have
an answer at hand. But it seems to me that if the ransom
program specifically targeted the BIOS password, and you
were able to attempt to enter that password several times,
after which the screen went black, you need to follow the
manufacturer's proceedure for recovering from a lost BIOS
password. Is that what you did when you shorted the
jumpers, or whatever you actually did?

Removing the hard drive and connecting it to another
computer will allow you to scan the drive for malware
and to back up data.

I guess you followed one of these video's?
https://www.youtube.com/watch?v=onI...

Anything shows up after removing HDD and if there is CD/DVD drive?
Did you put the memory back in to place properly?
