Blank Screen When Booting Up My Laptop

[dazedndconfussed]

Hello all

 

I have a Toshiba Satellite Pro C660-2F6 that I'm having an issue with. When I turn on the laptop, it shows the Toshiba logo, then a little flashing ' _ ' appears in the top left corner for a few seconds then the screen goes blank and stays like that. If I go into BIOS (I think that's what it is called by pressing f2 or f12) the screen works fine.

 

I've tried holding down the power button for 30 seconds, hold 0 whilst turning it on and removing / replacing the battery but to no avail.

 

Anyone have any ideas?

 

Thanks

That usually occurs with laptops when the hard drive has failed.

 

Try the following:

Step One

 

Please remove any media from media slots including USB, CD/DVD drive and flash drives etc. Disconnect all items connected to USB, hdmi, firewire ports etc.

 

• Start your laptop.

 

• Start your laptop while using only your AC cord without the battery.

 

• Start your laptop with battery only.

 

• If you can, please remove your CD/DVD drive and repeat the last tests.

 

• If that does not work, then we will move to next step.

 

Step Two

 

• Remove the battery and AC cord.

 

• Remove the bottom access cover/covers of your laptop and make sure the cooling path is free of fluff and dust. If there is dust in there, then get a can of

 

compressed air from you local hardware/computer store and blow out the dust.

 

• Check the heat sink on the CPU to make sure it is not loose. If it is not secure, then tighten the screws back down that hold it on.

 

• Remove and reseat your RAM modules.

 

• Replace your covers.

 

• Hold down your power button for 1 minute (Battery and AC still disconnected).

 

• Replace your AC power (not battery) and turn the computer on.

 

This is called a hard reset. If it works COOL, then replace your battery. Problem resolved.

 

• If that didn’t work;

 

• Remove and reseat your CPU and don't forget, if you remove it then it is necessary to clean off the old thermal paste and put new on as per this procedure for example:

 

Applying Artic Silver Thermal Paste

 

 

• If you have a removable graphics card, remove and reseat this. Most laptops do have an integrated graphics chip and therefore this step is not necessary.

 

Note: More information will be discussed later about graphics

 

• One little thing to try before we move on. If your laptop's motherboard battery (CMOS) is accessable, (little silver coin shaped cell that looks like a watch battery), then remove this for about 15 minutes and replace it just like you took it out. This will reset your bios to default settings and is certainly worth a try. If you can’t find your motherboard battery or don’t know where it is (or if it is soldered to your motherboard), then dont worry about that issue and let’s move on.

 

• Start your laptop. If your laptop is now working, problem solved, if not move to next step.

 

Step Three

 

• Remove your HDD and try starting your laptop. If it goes through the POST, and a black screen appears with the message something like “Operating System Not Found” and remains at this screen, then your HD is faulty or the OS is corrupt so we need to proceed to HDD test #1.

 

• However, if having the HDD removed and the fault is still present (Black screen or restarting loop), then you will need to move on to Step Four.

 

HDD test #1

 

• Restart your laptop with the HDD still removed. Enter the bios set up menu using your laptops recommended keystrokes to enter the bios screen. In the bios set up screen, set the first boot device as your CD/DVD drive, save and exit your bios. Your laptop will reboot to the screen that says “Operating System Not Found”. Open your CD/DVD drive and insert your Windows disk or Recovery disk. Shut down your laptop and replace the HDD.

 

• Restart your laptop. What will happen next is the laptop will boot from the Windows CD, and give you a series of options including; repair Windows, clean install of Windows, etc. The first option should be to try a repair. You could also try Hard Disk diagnostic/repair tools run from a CD/DVD as well (advice can be given on this). If you have only Recovery disks, then the option will be a recovery. If you are able to carry out a successful repair, recovery, or a Fresh Windows install, then it was only a software problem and your problem is solved.

 

• If however you are getting an error messages like; Can’t perform repair or recovery, or any other error message, then it is a great possibility the Hard Disk Drive is faulty. Replace the Hard Disk Drive and reinstall Windows. If this process is a success, then you have found and solved your problem.

 

Step Four

 

• The next thing we need to look at is either the RAM or the CPU, since both are needed to satisfy the bios pre-post test. Because of the nature of operation between the CPU and RAM (which can give the same fault condition), we need to eliminate the faulty component. In the majority of cases RAM gives more problems than CPU's, so let’s move on to working with your Ram modules.

 

• Shutdown the laptop.

 

• Remove all the RAM.

 

• Insert only one stick of RAM at a time and swap it between the RAM slots to see if the laptop will start. If it starts you have one good RAM stick and RAM slot, your problem is solved.

 

• Try the same sequence for the other stick of RAM. If that stick produces the fault, throw it out and replace it with new.

 

• If each stick still produces the fault, then you may have two sticks of bad RAM or bad RAM slots.

 

• Now here is a possible problematic situation, because if we have not found a fix yet, it could still be the CPU, because both CPU and RAM can give the same fault. Therefore, we need to eliminate the fault, although it is not as easy as some earlier steps.

 

What’s your laptop worth to you?

 

 

• You need to borrow a stick of known working RAM (bonus, because it costs nothing). Use a friend or family member with the exact model of laptop that uses the exact type of RAM, to borrow for testing (slim chance), or you can take your RAM to a Laptop Tech to test it for a nominal cost. One could even buy one if you wish to go that route, but that is certainly not the least inexpensive option. If this does not produce results, then we need to move to the CPU.

One could even buy one if you wish to go that route, but that is certainly not the least inexpensive option. If it turns out to be a CPU fault, and your laptop is now working, you have solved your problem.

 

• At this point, if your Ram and CPU appear to be fine, and the fault remains, we need to move to the next step.

 

Step Five

 

• Our next step is to check the GPU, the graphics chipset. This is not so easy, as most are integrated onto the motherboard. If yours is a high-end laptop then you may have a removable graphics card. Remove and reseat this, if that did not work, borrow or buy a known working GPU to test in your laptop..

 

• For integrated graphics, there are diverse ways to try a repair, but this requires the removal of your motherboard. At this stage you are most likely to have a motherboard fault.

 

• As you will have realized by now, this is not a fault with one common solution. That is the reason we have had to walk through your steps and process of elimination to identify faulty hardware before we can say it is most likely a motherboard fault.

 

• If one has gone though all the steps provided and has not resolved the issue, you are now at the point that you have to decide to try a new motherboard (this comes at a price), send the Laptop to an expert repairman to resolve the issue at substantial cost to you or go shopping for a new laptop.

Hello Dazedandconfused

 

I am not an expert but my laptop used to do this if I had a CD in the drive, as I think it thinks that you're trying to restore it or something.

 

Just something to check, Hope you get it sorted

prob your boot order is wrong &/or bios battery [button cell] has died

 

hit F12 when you see it

select the hardrive

 

dx

[dazedndconfussed]

Thanks for the replies. I've put an old HDD in it and it boots up fine.

 

Is it safe to assume my Original HDD is dead?

[dx100uk]

got one of those usb cradles

 

is it 'ticking'

[locutus]

F12 should take you through to Toshiba recovery options. If you can recover the HDD to its factory settings, it will at least be usable and able to do a HDD scan.

 

Failing that, can you burn a copy of Ubuntu to a DVD and boot from there and do a HDD scan?

 

 

The laptop quoted is an i3... my guess, 2011? If it is a hardware fault, maybe go to the retailer and quote SOGA to them?

 

If the retailer has gone bust (comet?) did you pay by credit card? there may be redress that way.

pretty much yes. if things were ok prior with no mods.

what make is the duff hard drive. if poss run a manufacturer diagnostic on it. if that fails RMA it if in warranty, or the whole lappy.
