I have had this problem several times with other Toshiba notebooks to the extent I almost cringe when anouther person tells me they are once again having the same problem. Hopefully, the following steps I give you will correct your problem... if not, your mobo may be damaged.

There are 2 levels of checking I want you to go through in order to try and fix this. The first is a minimally invasive procedure which wont require significant intrusion into the chassis. The latter will require a more involved dismantle of the laptop for troubleshooting . . . but first:

Rule out the obvious and maybe make it all better in a couple of easy key strokes >>>>
Please don't be offended or insulted by this first, very rudimentary check. I am sure you have already checked this,but just in case, this very simple next check could mean the difference between enduring 30 seconds of embarrasment and 300.00 for a new laptop because something got hosed when you cracked open the chassis unnecessarily trying to fix a sneaky,common issue. Try starting the computer and as it turns on, simultaneously press the “Fn” key and whichever numeric key also shows a monitor image and the text: LCD/CRT. This is a key combo switch that tells your computer to route the display output to an external monitor instead of the laptop panel. There are 3 possibilities – LCD (laptop screen) Only --- LCD and CRT (external monitor) Simultaneously – and CRT -(external monitor) Only. Try pressing the FN and numeric key combo a couple of times in succession immediately when the Toshiba Splash Screen appears – this is generated by the system BIOS and just because you see the splash screen only means that the laptop may be still set to output to an external display device only and just has not executed that instruction yet. I would also attach an external monitor to the laptop and try to boot.... if the display appears on the external, or if hitting the key combo causes the laptop LCD to come back on, then stop, grab yourself an ice cold Rolling Rock Beer (or Coke if you are not 21) and celebrate a simple easy conclusion to another laptop Maalox while pondering the exact phrases of praise and admiration you will be sending to Fix-Ya about me later from your restored lap-top. :-) If still no display.... take a deep breath and lets try the following procedures in the following post (too much text for a single post sorry)

SOURCE: On start up my computer says rtc battery is low or

Your RTC battery or CMOS battery is either dead or too low to keep the correct settings, windows will not operate correctly without the proper date and time kept. This battery has to be replaced for your system to operate. Below is the service manual that will advise you of the proper procedure to replace the battery. Once the battery is replaced, reboot the laptop, go to the BIOS screen and reset the date and time, then reboot as normal. In the case of your particular laptop, the laptop has to be disassembled down to the lower case and motherboard. The included service manual has the procedure for this.

SOURCE: my laptop says BOOTMGR is missing what does that means?

I have a acer aspire 4330 . The 160 gb sata drive died. I have a 500 gb sata drive install. The computer came with Windows vista, but I want to install Windows XP but the computer will not complete the install. It starts the process but fails when it gets to the statement "Starting to install Windows XP", it goes to a fault screen that says drive is corrupted. Ive tested the drive and it checks out fine. .

Any help would be appreciated

Toshiba Satellite L355D-S7815 had windows 8, opened up laptop and cleaned all the dust out and now when i turn the laptop on it shows the Toshiba screen but no F2 or F12 option's.

What you are talking about is called no POST. You either shocked the cmos and the bios wont load or something is not hooked up right.

It wont boot, goes to black screen with whit blinking dash

Yes, this sounds like the traditional black screen issue, but it's different! This machine is a Dell Dimension 3000 with XP. System won't boot. After Blue Dell BIOS splash screen with F2 & F12 options, it just goes black. There will ultimately be a white cursor in the upper left hand corner. I can edit BIOS with F2, I can get in to the boot menu with F12, but I can't do anything after that. I can even get in to the Safe Mode menu (F8), but it never boots.

My Laptop wont start properly. It just starts, shows Toshiba The leading Innovation message and goes off. I then get a blank screen with a cursor at the top left hand corner. Power cable is working,...

This could be a failed hard drive. As soon as you turn on the computer, go into BIOS (I think you hit the F2 key on Toshiba systems) and check the list of IDE or SATA devices. If you do not see a hard drive model number there, that is your problem.

If you do see a hard drive, you may be able to get it to work with a System Recovery CD. It may have been corrupted by a virus or power failure during a write operation.

When I turn the laptop on (L350) the screen starts with the "Toshiba leading innovation" page then is blank- dark grey. It does not respond to any keys including F2/F12

The laptop can not detect the hard drive please remove the hard drive and then reseat it if the problem persist then replace the hard drive.

Can not Boot from OnBoard SATA Hard keeping looping...

Turn on (or restart) your computer.
When F2 = Setup, F12 = Boot Menu appears in the upper-right corner of the screen, press <F12>.
The Boot Device Menu appears, listing all available boot devices. Each device has a number next to it.
At the bottom of the menu, enter the number of the device that is to be used for the current boot only.

If this works and you want to change the setting permanently do the following:
Turn on (or restart) your computer.
When F2 = Setup, F12 = Boot Menu appears in the upper-right corner of the screen, press <F2>.
Use the arrow keys to highlight the Boot Sequence menu option and press <Enter> to access the menu.
NOTE: Write down your current boot sequence in case you want to restore it.
Press the up- and down-arrow keys to move through the list of devices.
Press the spacebar to enable or disable a device (enabled devices have a checkmark).
Press plus (+) or minus (–) to move a selected device up or down the list.
