Try taking out any cords and take out the battery and hold the power button down for 30 seconds then put the cord back in and try to turn it on, then put battery back in.

PCGuru · Answer

If it is a Power Button problem, then you might be able to use the QuickPlay Button as a substitute.  The problem most likely is a ZIF cable that connects the motherboard to the power button.  That cable controls sound too.  You can either order a new cable....they are hard to find at the moment.  Or you can swap the cable that controls the touch buttons. The cable is a ribbon cable, which weakens from pressing the power button due to flexing.

Toshiba Satellite A135-S2246.

Plugging it in, the power light comes on, but no battery-charge light.

Power button completely unresponsive.

Tried the solution here- remove battery and power, hold power button for 30 seconds, replace battery, turn on.

Worked like a charm, and my heart attack is aborted!

In working with computers for over 20 years, this "hold the laptop upside down and press the power button" stuff makes no sense to me.....but it worked for me!  Why is this?  And thanks so much for helping us out.  We had tried two batteries and different AC adapters.  Just about to pitch the laptop when our search found you.  Thanks again.

Well the power on my toshiba woludn't work neither would the ethernet so I replaced the motherboard. took six hours, but I finally finished with the help of my friends Peaster and Hampton. It turns out when I put the memorey modules back in onne was askew causing the computer to constantly turn on and off. SOLUTION! I took of the back cover and reinserted the askew memory and it worked like a charm!

Boy I wanted the up-side-down method to work for my Satellite P35-S6292.  I was doing some pretty odd things, *before* I found this thread, in order to power-up.  So much so that I snapped the power button and had to dismantle the machine to super-glue it back in place (this model needs dismantling occasionally anyway to clear out the suffocating dust bunnies). But alas 30-sec-up-side-downing did not work for me...

BUT despite the fact that pressing the power button will still not [on its own] start this machine,..
If I press its 'Music CD Button' (i.e. the top [furthest back] media button) first and *then* press the power button - shazam!  .. Glowing Blue Power Button Joy!  At this point I don't care much why the power button doesn't work by itself, just so long as the voodoo of the past (e.g. plug-in-out cord whilst holding button, etc.) isn't required.

I have a toshiba a135 and I was having the same power problem mentioned. Just quit working one day.  I would plug it up, and the plug light would come, but no battery light, no nothing
I did the upside down thing, only when I flipped it right-side up, plugged it in and then HELD THE POWER BUTTON DOWN FOR ANOTHER 30 SECONDS, it worked.  Couldn't believe it!
Thanx for the help.

Actually it could be anything... from a broken power button, passing thru a worn-off battery, ending on a faulty motherboard.

First check if you have ANY indicator light lit when you plug the AC adapter in. If a light turns on, then the AC adapter is delivering correct power to the system, but there is other cause that doesn't allow to power on properly. 

Try to power it on using only the AC adapter, removing the battery. Also don't rule out that the AC adapter itself could be failing... especially if it has frayed wires, has melted plastic, etc. In that case it is only that the battery is all drained. If someone has a laptop like yours, check on the label if the AC adapter delivers the same Watts, the same volts and the same Amperes. (say, your AC adapter coud be a 19.5V, 80W, xA) and try that adapter on your computer, with and without the battery. 

It doesn't look like AC adapter/battery issue?

If you can and know how to open your computer... remove the keyboard, remove the memory modules, remove the optical drive and the hard drive, remove the wireless card and bluetooth card if it has it... for sure you can find manuals on how to do that over the internet. Close the computer and try to power it on. If it turns on, no matter how many error messages you can get, now you know that any of these components you removed could be guilty. So.. add them one by one... and try to power on the computer after adding each. if it suddenly doesn't turn on after adding one piece of hardware... Voila! There you have the guilty one. 

But if ALL this has no effect... Jesus... The guilty is the system board (AKA motherboard)... you could either replace it or get a new computer, but it wiiiiiillll cost. 

Good luck!!!

Thanks vivianli108,


My colleague has the exact model as we bought from the same vendor.

1st test
I tried her battery and & slot into my laptop and the result: My laptop did not turn on, the led did not light up. Then I slot my battery into her laptop and the result: Her laptop did not turn on either. Conclusion: My battery is faulty while hers is OK.

2nd test
I tried her adaptor & connected to my laptop (without battery) and the result: The same problem persisted. Conclusion: Both adaptors (mine & hers) are perfectly OK.

I'll send my laptop to my vendor first (before to Service Center) & shall let you know what would be the suspected problem(s). My laptop contains a lot of my office works and I never did any back-up (**silly me**). Is it possible to copy the hard drive into my colleague's laptop without having removing its bottom? Thank you.

Cheers!! (^-^)

i had problem with my Sony Vaio not powering up at all (no light etc). I tried everything (wiggling the power adapter, removing battery and pressing start, removing RAM), and occasionally it would start up and work for a few hours/days. Lately, it just wouldn't respond to any of these "fixes", so I read this site with much interest and tried the upside down fix but alas that had no success. Out of sheer desperation I just plugged an external monitor into the side of the laptop and the machine now starts up again, take the cable out and the machine instantly crashes. I don't know whether it's the effect of the external monitor, or just having the cable in the socket, as I haven't got a spare monitor cable to try it with (my monitor's cable is built in).
I guess it's not a practical solution, but it may help in an emergency!

Found this on the first page...{OK.....TRY TAKING OUT ANY CORDS AND TAKE OUT THE BATTERY AND HOLD THE LABTOP UPSIDE DOWN AND HOLD THE POWER BUTTEN FOR 30 SECONDS THEN TURN IT RIGHT SIDE UP AND PUT THE CORD BACK IN TRY TO TURN IT ON THEN PUT BATTERY BACK IN}

I just replaced the Power connector for a Sony VAIO that had broken. After 2 1/2 hours of careful removal of EVERY piece on this Laptop including the Motherboard and disconnecting all the TINY ribbon cables, I was able to replace the power connector. 

I then re-installed EVERY piece I removed. I plugged in the power cord with the battery installed and the Battery light just flashed rapidly. When I press the power button, the green power light was on with the button pushed but off when I released it. OK long story short. Instead of dismantlement the laptop again, I tried the above solution. IT WORKED!!! I don't know how or why it worked but it did. I was able to get the laptop to power up without the battery in place. Now I think that the problem is a bad battery. The laptop won't recognize that the battery is plugged-in.

OK, I have the same problem with Toshiba Satellite. The laptop lights would go on, then you hear the fan and the CD drive running for 2 seconds then it dies. I found the solution to this problem in other forums and feel that I have to share it with everyone. 

Solution:

1.Unplug AC and remove battery. 
2. Hold power button for 1 minute (some claim holding it upside down helps..dont ask me why) 
3. Leave laptop for 1 minute
4. Insert battery back into laptop and plug in AC.
5. Turn on


It took me several times before I finally get it to work. Make sure the battery is charged before doing this.

I was so happy when this worked for me. I was so frustrated. I just have to share this with everyone else.

Laptop will not turn on.
