SOURCE: my toshiba satellite l455 won't start up it

click on F2 and that will take you to the Bios setup, check that your hard drive and Ram (Memory) are both online if all is ok and no problems press F12 it might take you to a diagnostic screen prompting you to perform a diagnostic test, if so do the tests and write down any errors given, if there is not diagnostic tool you might get the options to restor factory defaults this option will reset your computer to its original state and you will lose all your data. Another option if you have the operating system's cd (windows xp, vista etc) from the bios (F2) change the boot sequence to cd (just click on Cd/DVD Rom)only and reboot, windows will ask you if you want to repair, if all your hardware is ok and you should be able to solve the problem good luck and all the best

SOURCE: My toshiba satellite laptop won't turn on

There are a number of things that could cause this.
Starting with the simple diagnosis and moving onto more difficult problems:

1.) Check the On / off button is not sticking. If it does not free up after pressing it, the laptop will shut off. cleaning the area with some meths or isopropyl alcohol will help free it (laptop unplugged)

2.) If there is a small cut off switch (located just below the screen where the lid hinges close, see that it is not sticking, this causes the aptop to shut down if the lid is closed.

3.) Next, check to see if it will work plugged into the mains, with the battery removed. If it will, then get the battery checked. Check also that if the battery is fitted, the latches are in the lock position

4.) Check the AC adaptor green led light is not pulsing or flicking, it should be steady green. if is IS flickering, try a universal one. If the problem persists, you may have an internal fault on the motherboard

5.) Check the security of the DC jack, if this is loose or sloppy or feels worn, you need to get the jack replaced (see below), leaving it in this condition can cause arcing and permanent damage to the motherboard

6.) Check the adapters output voltage using a voltmeter, with the red probe on the inner contact and the black probe on the outer contact.

7.) Try swapping out the ram (if accessible) sometimes a ram module goes bad and stops the laptop from switching on, at this stage, disconnect the hard drive and see if it switched on with it removed.

After that, you are almost certainly looking at a strip down of the laptop, depends on whether you feel comfortable doing this..otherwise a repair technician will be needed

Possible causes will be:

A. The DC jack cable from the port to the motherboard is damaged (check continuity with a multimeter set to Ohms)

B. The Power capacitors or diodes on the motherboard are damaged (probably new motherboard needed)

C: The laptop has overheated at some point and the graphics chip has unsoldered, CPU fan failed, or CPU dead.

A good technician will be able to diagnose the fault from a few tests

SOURCE: Toshiba Satellite C655-S5082. Won't power

Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.

Locate, and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
  3. In the right pane, if you have UpperFilters, right-click UpperFilters, and then click Delete.
  4. Click Yes to confirm the removal of the UpperFilters registry entry.

How do I reset the bios password on a Toshiba Satellite s875-s7356


There's probably a set of jumper pins, labeled "B500" or something specific to your machine somewhere on the motherboard. Short those pins while turning on the power. Wait until it finishes booting, then turn it off again. Disconnect the pins, and it should start without the password.

Toshiba Satellite L505-LS5014 made a popping noise and then turned off. It had done this 10 minutes before but this time it won't turn on. Any ideas on what's the problem and how to fix it?


The problem may be in the DC jack in the laptop, sometimes solder touch up or DC jack replacement is required. the computer will need to be dismantled down to the motherboard level to address this.
