SOURCE: jumper settings

There is no jumper settings, it is just a small bridge aside the bios Chip. you bridge the two pins and power to reset cmos.

A much easier way is removing the Cmos coin shaped battery from motherboar for few seconds, and put it back, this will reset Cmos the same .

SOURCE: My Toshiba Satellite M115-S1061 is completely locked up!

This is an easy process but you have to take the keyboard off. To start off take the main battery off, on the bottom side of the PC ther is a screw or a pair of screws that hold on the Keyboard(normally labled with a pic of a keyboard or the letter "K").

Once you have removed the keyboard screws you can turn slowly and gently pry up the keyboard, be sure to do this carefully as there are wires that attach the keyboard to the laptop. Once you have lifted the keyboard up u should see the "guts" and a small round battery.. Carefully take the battery out then replace it.

Now. The real question is what do you mean by "LOCKED UP" will it not turn on or is it frozen on a screen or what ? There might be a better solution to your problem than doing what is described above.

SOURCE: Trying to locate the cmos battery for Toshiba Satellite L25-S121 laptop?

On the Toshiba Satellite L25 S1217 Laptop, the battery is indeed to the left of the wifi card. I was having a problem with a bios password and had spent a considerable amount of time looking. However Instead of taking the whole laptop apart, I removed the wireless card and used a precision flathead to maneuver the connector out of it's socket. after a few seconds I booted the laptop, with the battery still disconnected , and no password prompt! using the same screw driver, I was able to get the connector back into it's socket, and put the wireless card back in. it runs fine now. the trick is to only pull the connector out only enough so that it's not making the connection, if you pull it too far you will have a tougher time guiding it back into the socket. I hope this helps a lot of people with the same problem.

SOURCE: Toshiba satellite a205-s5804 laptop will not start

Hi, there are a couple of possibilities:
1. If you are able to start the laptop on battery then the dc connector on the motherboard may be broken or have come loose, in which case take it in for repair.
2. The power switch may be broken, again take it in for repair.
3. Tip of the trade: Disconnect the battery and plug in the charger, see if it will switch on. If not then put the battery back in with the mains still plugged in and see whether it springs back to life.
4. Tip of the trade 2: Leave well alone for a couple of days without any battery or power connected then plug back in and see if it will switch on.
Removing the BIOS memory, don't know where you saw that but not recommended at all unless you want to render your laptop completely useless. Don't attempt to strip down unless you are technically experienced with disassembling a laptop.

Sounds like you have a bad motherboard, oh and you can't hear RAM, either it's been hit by a power surge or it's burned out...

My Toshiba Satellite L645D - S4056 Laptop is not charging. When I remove the Battery to try charge it directly the lapop will still not pick charge. Right now i dont know if its the Charger or the laptop...


From what you I can understand the issue is the charger. Without the Battery the Laptop will not work as the Charger is not giving power to the laptop.
If this is the case you require a new charger. I would suggest testing with a similar charger if a friend has a similar model or taking it to you local shop before you spend money on buying a replacement.

I have a Toshiba Satellite L465 S4056. My fan runs on high constantly, but my computer isn't hot. Is there anything I can do to make it not run on high?


Hi, if the airways are clean and the laptop does not get hot it is possible that your computer needs bios updates... first go into the bios to see what version you have then go to toshiba web site and search your model support and download section, if there is a bios update see if the version is newer than what's on your computer, if it is then sure follow the instruction to update.... I hope that helps.
