Laptop shutting off

I am having problems with my power supply, it connection to my Toshiba laptop M35X or the battery. The unit powers up but frequently shuts off on its own. When this occurs the battery is almost discharged. I can plug the power supply in, power up but it will still turn off randomly. I note the green AC lite AND the battert status lite orange/green will often flicker or turn off when the computer is turned off but connected to the power supply. I can wiggle the power connector where it plugs in to the back of the computer and usually get the lights back on. I suspect a loose connection with the female adaptor plug for the power supply, but I wonder if anyone else is familiar with this problem. If this is it I will need to open up the computer to check or resolder this connection. How big a project is this ? I checked the power supply with a voltmeter and it seems ok. Thanks for any help.

Re: laptop shutting off

This problem has happened to me on several occasions. I found that the connector that you plug your power supply into on the motherboard gets loose. Not making a good connection and like you said needs to be re soldered. Before attempting this, stick a small screwdriver in there and see if it's loose. If it is, then EVERYTHING needs to come off to get to it. Not a quick project. I suggest you take pictures along the way just in case. Good luck!

Notebook will not power on when on battery, but will run on the battery after it boots

Booting process take so much current from the battery. If the battery is not capable of supplying enough current to boot up, this may happen. Replace the battery with a new one. the present battery inside it will have insufficiant current for first boot up.

Most likely you have a damaged power problem. See if you can remove the battery and restart the unit. if it works, the battery is bad. If not, test the power supply. Next check the power supply connection. You can verify this if you have a way to charge the battery and see if the unit works with out the power cord. Or take a chance on $20.00 and replace the power DC jack.
Good luck.

My Toshiba Satellite M35x-S149 laptop shuts off several times a day...we have replaced the battery and most generally have the battery out and using DC power cord. Can be working on it, and click, it goes...

This could be the power inverter. It has happened to a few people I know. First off I don't think you should have the battery out. I think the power distribution function needs the battery in to complete it's component structure. Next, don't leave your laptop on a cushy surface (bed, pillow,couch, etc.) This blocks the fresh air intake for the processor. When the processor heats up, the unit will shut off. Repeating this will eventually toast your laptop altogether. Make sure no dust has built up on either the intake (bottom) or output (side). Use a can of compressed air to clear the unit. UNPLUG and REMOVE BATT First!

If all is clear and it's still happening it very well could be the power inverter, it's about 60 bucks and you can do it yourself. You may find it cheaper on ebay or something. You will need the actual part number off the inverter. Google "Replacing power inverter for toshiba" for more info. Hope this helps!

I dont have a power supply for my laptop can I hook up my desktop to it

There is no power connector from a desktop computer that can connect or supply power to a laptop computer.
There are replacement power supplies available on the Internet or at your friendly computer shop.

was the power jack that 'popped off' the one in back of laptop? sounds like perhaps part of that shorted out, and only one side of that connection is running

M35X Screen went black and will not come back on after shut down, reset and power up

Try to connect to external monitor and see if you see anything. Of course when you do that you have to hold at the same time fn key and the key that has a blue picture of computer screen.
