Toshiba Satellite Won't Power Up

My Toshiba Satellite L635 won't give me any indications of functionality. I left the computer asleep overnight (I do this often without ay problems), but when I attempted to wake it up none of the indicators lit. The system was still asleep with the power indicator blinking at 09:00, though by 10:00 it wouldn't power up. When the battery is critical (7%) and my system sleeps it will generally hold a charge for at least 24-48 hours. I have attempted a 'bare-bones' start-up (with all unnecessary components disconnected [including the internal components such as the monitor and keyboard]).
With the 'bare-bones' setup I attempted first to start it with the battery attached and using the power button, then with the charger and power button, neither worked, I then ran the same test again, but I attempted o short the power button connectors with a pair of stainless-steel scissors; this didn't work either, so I ruled out the power button being an issue.
I don't have proper troubleshooting equipment (another battery and charger) so that may be an issue.

Below I will include all information that may be relevant.

Mfg. date: Sept. 2010
Date of purchase: Dec. 2012
Model: Toshiba Satellite L635-S3030 SYSTEM UNIT
Part # on case: PSK60U-00600| <ES5.0>
Processor: x64 Intel Celeron dual-core

The information below was found on the system board:


On another sticker: insyde

Insyde H2O ©
AS22

Printed on board w/ outline: BM10-1

There is also a table printed on the board with red dots on certain items. I have recreated the table with Excel. A red highlight means that there is a red dot on that item. The one with the question mark (?) was covered to the extent that I can't be sure of what the number was.


I would appreciate any help you can provide.

Don't give away serial numbers. - G

    So you have taken the battery out, disconnected it from the power adapter, held down the power button for 30 seconds and then placed the battery back in and the power adapter and tried powering it on?

    I will try that as soon as I can, but what exactly is that supposed to do?
  3. What that does is short any electrical charge on the motherboard as well to companents. Its basically discarging the laptop of any power. Give it a shot, I've done it several times with this issue on my tech jobs and it has resolved the issue your describing. But make sure all your compenents are installed, put the laptop back together, sounds like you already took it apart.

    I tried that (multiple times, to be sure) and attempted to power up my laptop multiple ways. I saw no results. There were no lights and the fan didn't spin up.

    It is worth noting that I used a universal charger set at 19v to charge my laptop. I previously used a universal charger set at 18.5v. The input labeled on my laptop is DC19v 3.24A.
  5. then I'm at a loss, unless your adapters shot.
  6. I had the same issue last night and tried the battery-out thing.......... it worked!!!! don't know how or why, but don't care either!!! THANKS!!!!

    On mine, I found out my power adapter was not giving the correct voltage the laptop was looking for. Changed power adapters and runs great! I know this is not a cure all, but I don't see anyone responding with that possibility. EDIT: Sorry, there was one.... LOL

  15. Hi,
    Had same problem with my Toshiba laptop after having it shut down since before Christmas; went to Toshiba support onlineand they gave me same info as you Tom - worked (turn off, take battery out, hold power button down, after some time of a grey screen it worked! ) I'm making note of your site Tom for future. But I do have a question: the 3 lights on the outside front I could have sworn one was green; when laptop is off, one blinks white, when on it is a constant white and the one to the right is a shade of orange - is this how it should be - what are the 3 lights on front for?
  16. It did work for me as well.
    Steps:
    1. Disconnect laptop from power cord
    2. Take out battery
    3. Hold power button for 30 seconds
    4. Put battery back
    5. Connect to power cord
    6. You can see that the orange light is on
    7. Press power button to boot up laptop

  24. I tried completely every trouble shooting method, the forum had to offer but then I thought. What will happen if I removed my machines C-mos battery? Then return it to its rightful place. Yes, th perfect solution nd it worked.
    Ones my pieced my machine together, I powered it back on. There weren’t any blinking led’s, with my screen back on. I got a display message something about; your c-mos battery is removed, blah blah. Ignored that nd entered F2, 4 setup nd configured my dates Oh, nd make sure your machines battery is having power for when you turn it on, nd lastly make sure your Critical Battery Wake-up setting is disabled in th C-mos setup. That should come as a recommendation, Yawl ar welcome.

    Hi Jakes, do you mean you replaced your C-mos battery with a new one or did you put the same one in again?

  27. I was re-installing windows on my friend's Toshiba laptop Dynabook Satelitte AW2 when the laptop suddenly went out.
    I tried all things possible to revive it in vain. The power adapter works ok as I connected it to my Toshiba and it is working great.

    There is no light at all from the laptop indicator lights. I took it apart to see if there is anything I could do, and realised that everytime I do connect the laptop to the adaptor, the adapter light(green light onthe adapter that shows power on) goes out, when I do disconnect it from the laptop, it comes back on.

    Am I fucked?

  35. what does change the power button mean?
  36. Maria_37 said:

    Might mean they think you can take it apart and have a spare power switch to plug in? I dunno.

    Make sure to try the first suggestion from lostsurfer - It worked first time for me. (Thanks!)

    Unplug ac power source to computer and remove battery.
    Then hold down power button for at least 30 seconds.
    install battery and plug in ac power again.
    Some people said it took a few tries before getting back to normal, so maybe hold down the switch longer - i held it down for 90 seconds. Keep trying, since this worked for others here.

    Apparently, the circuitry had a charge on it that needed to be discharged. If so, it may happen again?

    Had to do this about 3-4 times with my Toshiba Satellite S855d-s5120, but it worked. Thanks!!!
  38. Hello Guys!! I found the soulution to the first question of all. is the button of the power. you to dissarmed the laptop, break and take out the button ( I did that ) and then make sure it fits again. The laptop wont turn on because it get stuck with the foam inside. Hope you guys solve the problems with this one. Have a nice day.
  39. it's only a temporary fix for me though. It works until the next time I need to plug it in. Then it just charges forever but the battery percentage doesn't increase. I don't know if I should purchase a new battery or if that will even work. At this point in time, my computers about 3 1/2 years old, but isn't slow or have any of the other problems an old computer usually has. It's a Toshiba Satellite C50-A-002. If anybody has a more permanent solution for me that would be very appreciated! Cheers.
  40. if the power button reset dont work, try replacing the cmos battery,
  41. I wanted to do the battery thing on my satellite C75 but I didn't had the right screw driver so I just pushed the on/off button for 30 seconds and that worked as well :-D

  43. Wanted to chime in here in case someone had my issue. I had no power or lights. I tried the 30 second power button trick to no avail. I ended up opening the case and doing some troubleshooting. I used a multi-meter and found I would only get 19 volts on the DC power jack harness if I grounded it against the jack casing. I also didn't get any continuity if I checked the black wires and the jack casing. I grabbed my handy dandy soldering iron and resoldered the ground wire to the jack casing/ground tab and WALLAH(!) I have power back to my Toshiba L75 (L75-B7270).

    I hope this helps someone.

    I have a satellite pro C850 was using it earlier and it stopped responding completely, turned it off with power button and back on, no problem. It's just done it again, powered off and now when I power back up, I just get a black/grey screen. Tried the battery and charger lead out, hold power button for 1-2 mins and power back up with battery and charger but still no joy..........
  45. Looks like Tosh has design problems with their satellite laptop series. They should be legally held liable for damages from selling defective devices to consumers. Hope they get mailed soon.
  46. Just wanted to throw in my two cents on this issue, as I recently dealt with it. I had already tried the power button thing several times to no avail. I opened up the case & checked the power jack connector. It was loose so I reinforced it. Still problems. I checked the voltage of the power adapter 19.3v. checked the pc jack, 19.3v coming in. Seemed enough as the info says 19v. But I had similar Toshiba laptop here in the shop, so I connected the AC adapter to that laptop. Same symptoms appeared! I tried a multi voltage universal adapter to my laptop. I works! Checked the voltage 19.4v!! So it was that 0.1v drop freaked out the laptop.
