Toshiba m35-s456 no power

My toshiba all of a sudden shut down and now won't come up. when i plug it in, it does not show any lights on. someone looked at it and told me it was a motherboard, but if that is true, why won't the battery light at least turn on and show charging? I also don't trust these people who told me this. Can you help me?

To test if the adapter is faulty check it with a multimeter.
Test the output voltage on the connector that plugs into the laptop. The voltage should be 19 volts (the voltage is printed on the label on the adapter) or slightly higher because the is no electrical load on the adapter.
If there is no voltage or if the voltage fluctuates when you flex the power connector, then the adapter is faulty.

If the adapter is OK, then plug it into the laptop and the jiggle the connector a observe the charging LED light and if it flickers the fault is the power connector on the laptop. This can be repaired, it needs to be resoldered or replaced.

(Toshiba Satellite M35-S456) G-Force nVidia 5200 graphics card


To determine if your video card is faulty, connect an external monitor to the laptop, power up the monitor first and then the laptop.
The video data will automatically switch to the external monitor and if you see a normal image then the video card is OK and the fault maybe the video cable, it may need reseating.
If the image still has the strips, the same as the LCD screen then the fault is most likely the video card or video RAM..
On some laptops video RAM uses part of the main memory modules, reseat the RAM modules and if this doesn't fix the problem then the fault is the video card. This very difficult be fixed becaused it is part of the motherboard.

Toshiba satellite m35 power issues


Hi !
While power off, disconnect the power adaptor.
Take off battery.

Plug the power adaptor back and try to start !
Is it running?

If yes, than the power adaptor is OK.

Now shut down and disconnect the power adaptor.
Put back your battery and start!
Leave it untill you 'empty' the battery.
Do not start your laptop.

Plug the power adaptor and do not start your laptop yet.
Is there a led idicator showing that the battery is charging ?
Does it shows when the battery is full charged (e.g. red/yellow=charging, to green/off charged)?
If not, leave it for at least 3 hours. After that, start your laptop (adaptor is plugged) and see if you still have an icon saying charging 99%.

If that is the case, then something is wrong with the battery.

Check your warranty, and replace it.
DO NOT OPEN the battery - nothing interesting you will find inside - nothing you can do !

Regards.

Toshiba m35-s456 , cant turned on


Your model of Toshiba Satellite is well known for the power plug to go bad. the pin in the back breaks the solder on the system board. Toshiba actually got sued over the issue and they used to fix this for free, the bad news is that they don't anymore.

To check if this is the case on the back of your laptop where you plug your ac adapter see if the pin will wigle with a screw driver or something. If it does then this is the problem.

The good news is that you probably can take it to a computer repair shop or a toshiba repair center to get it fixed.

If you want toshiba customer supports phone number it is 1-800-457-7777

Toshiba satellite m35-s456 my computer lights come on but it will not boot up?


The same thing happened to me today. I think it is the power supply connection to the mother board. I had to replace the motherboard 2 yrs ago with the same symptoms. I can reboot the computer 20 times and once the laptop will boot-up OK. But most of the time the power button will come one but the screen is blank. I'm not sure if I am going to get a new laptop or just replace the motherboard...again...

Laptop won't power up


Have you tried to start in safe mode? (hold the f8 key while booting). This will allow you to go back to a boot sequence that worked. You will need to go to start and select restore. Could be under accessories
