How to bypass setup password on a toshiba satellite A105-S4074

You can fix this by removing first removing all power, then remove the plastic cover above the keyboard, removing removing the two keyboard screws.
You'll need to fold the keyboard in such a way that you don't damage the cable.
You will see the wifi card just to the right. It's the only card there. It is held in place by spring clips. Remove the card from the connector.
There are two solder contact points labeled "C88". Connect the power adapter to the laptop now. Short the two contact of "C88" and press the power on button. The unit should boot to the windows screen. Once it boots, you'll have to update to the latest BIOS.

Service stop work, i cant unlock my lap top

Remove the plastic piece above the keyboard.
Unscrew the 2 screws on the keyboard and lift it up gently. You don't need to disconnect it.
Now unscrew and remove the modem card in the center.
On the system board you will find 2 solder points c88. Short those 2 points out while you press the power button on, which will reset the bios password.

Toshiba satellite a105 bios password dont have send me pleas how unlock phoenix bios password

1), when taking your computer apart, take out the battery and unplug it always
2), Remove the plastic cover piece above the keyboard, called the keyboard bezel. this is the piece where you can see the speakers. it is a bit difficult to get the plastic retaining clips to pop loose, but if you are careful, you can use a small screw driver and slowly between the two screen mounts. this is done with the screen all the way back. you could use a paper clip with a little 1/8" bend at tip to do this also. (it is a tight working area) there are three retaining clips that have to come loose the others are fairly easy to pop out . once this is bezel is off the rest is fairly simple. please take your time and be patient as if your not you could damage it .
3), Remove the keyboard. Remove the two screws that are evident once the bezel has been removed. These hold the keyboard in place. Lift the keyboard up from the screw side and the retaining clips at the front of the keyboard will lift out. (there is no need to pry here). Once the keyboard is loose you will have to either leave it connected, just off to the side, or disconnect it from the mother board. The keyboard cable connector has a black clip along the top of it. just lift this clip up a little and the keyboard cable will slide out. (the keyboard cable does not have a fixed connector, but is just a ribbon that is held in place by the black clip along the top of the keyboard cable connector) Once you have removed it you will better understand what I mean.
4) Remove the wireless card. It is the only card visible at this point. It is connected by metal spring clips. just unclip in a similar fashion as removing ram. You do not need to disconnect the wires connected to card, just move card over to expose area below card.
5)you will see C88 clearly labeled right next the jack that the wireless card plugs into. There are two little solder squares (approx 1/16") at this location. *** At this point plug the power adapter to your computer again. ***
You will have to jump the two solder squares at label C88. .use a small wire or paper clip but make sure you removed all the coating off the paper clip first with pliers so it can make a good contact on both ends. hold it in place on these two solder contact squares and press the power button to boot your computer. here is a link to guide you for disassembly it is the same family of laptops although its for a a135

Bios Pasword

Unfortunately, if you can't remember your bios password you'll have to reset the CMOS. This is usually done via a jumper on your laptops motherboard itself, or removing the battery on the motherboard while the laptop is unplugged and the main battery is taken out. Be very careful when opening up your laptop, make sure all the screws needed are removed, as they are easy to miss. If you don't feel comfortable opening up your laptop, I would recommend taking it to a certified technician.

If you've lost the bios password, you'll probably have to 'flash' the bios. If you feel comfortable enough, you can dismantle the laptop and remove the motherboard battery for several minutes, then replace it and reassemble the system, see if the password has been cleared. (Note: The motherboard battery is NOT the laptop battery; you have to remove both!)
