If you haven't given up on your computer the solution maybe not the switch, but something loading the internal supply. The most common piece to fail is the cpu. The failure is usually from excessive heat with the cooling path clogged or not letting the air to get the opening on the bottom for the fan. Also as laptops get older the cpu's heatsink grease needs to be cleaned off and new heatsink grease put on and at the same time a thorough cleaning of the heatsink fins. If the cpu fried you may see some brown hazing on it surface.

Some of the manufacturer used the same switches, so try to find another one which is actually the same but fit to that part, before buying of new board

Hello, My name is Vahe and I have got the following problem, I have forgot my BIOS password and I can't to turn on. Laptop model Toshiba satellite A200-13M. So I have got some solution to delete...


The most common way that most of us know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased. Hope this helps

Try removing the laptop from the doc, pulling out the battery, hold the power button down for 10-20 seconds, and re-install the battery.

This should drain out the laptop and it should boot up properly without the dock.

I have a toshiba satellite pro, i use for a 2 days and then it never turn on again. i try everything still not coming on. i need help please its a seccond hand laptop.


Try removing the battery and using just the power supply first, if this works then it is a battery fault, is that doesnt work then try another power suppy or get your power supply tested, if not either of these, then it may be the PSU connector inside the laptop

How do i change HDD in Satellite A135


You will need a 2.5" SATA HDD to change with. (the operation must be done with the laptop shut down)
Unscrew the container with the HDD sign and remove it. Being SATA you just have to plug
it in the connectors and it should work. (of course you'll have to format it and reinstall your OS).

I have the same problem with my dell inspiron 1520 laptop


You have an obvious electrical problem. It could be that the switch on the power module is faulty.

Remove the hinge cover and depress the power switch on the power module. If the system is starting without hinderance then the issue is the tab under the hinge cover is not making proper connection with the switch below. If the same problems persist when you go directly to the power module then the module has a faulty switch. Radio shack has those tact switches for $3.58. You can either replace the switch or replace the module.

Good Luck

try removing the battery, and unplugging from the wall. now press and hold in the power button for at least 30 sec., reinstall battery and ac adaptor and try to power on. if that doesn't resolve, you may need to have the RAM (memory) checked out, as system memory is usually shared for video

When you say you turn it on, do any of the lights on the laptop light up? Does it make any beeps?

Have you done anything to your laptop or has anything happened that you think might have caused this?

Start off by simplifying your setup as much as possible to eliminate any outside influences.

Remove anything plugged into the laptop. Then unplug power and remove the battery. With battery out and power disconnected, hold down the power switch 15 seconds (this can clear out a corrupt BIOS).

Reconnect only AC power and try to power up. Verify your AC power has a power light lit up and all connections are snug.

If no go, try only with the battery and no AC.

Still no go, remove battery and any removable drive (CD, DVD, etc.). Connect AC power and retry boot.

If you feel comfortable removing the hard drive, remove it and retry boot.

If all drives are out, all external and internal devices removed and still no display, try removing the memory and putting it back in (reseating it).

Let me know if that helps or if you need further help.

Toshibba laptop a135-s2276 ,my mother bords smd chip does not work so display of screen does not appear


The problem is well known witht this model Toshiba - the problem is the fan stops working and then hence shuts down to prevent overheating - it does not take long once the laptop is hot. Without replacing the fan just reboot the laptop until you hear the fan start again on reboot.

Toshiba Satellite A135 is DEAD!


Open the back panels, blow out EVERYTHING and remove and re-insert everything. You could just have dirty contacts somewhere. The dust from the fans also travels around inside the computer.
