Question about Toshiba Satellite A135-S2246 Notebook

1 Answer

How do i replace a coin cell cmos battery soldered to the motherboard? I have a satellite a135 that runs straight to the bios password screen. i've tried shorting the JOPEN1, but it didn't work. i tried all of the passwords for pheonix bios, but those didn't work. i just need to know if i will need a soldering kit or if i simply need to take the battery off the motherboard.

I don't know how you are getting this problem, what you see is a "power on" password. This normally occurs after a bios battery is replaced and is a security measure. I can only assume the Bios battery died on you and lost the settings.

You have a couple of options: Contact toshiba and ask them for a bios master password. You may also need one for the hard drive access as well. They will ask for proof of ownership.

You will not find any back door passwords. Even if you were to use Dogberts pass hacker (google dogberts reverse engineering), the hard drive would still probably be locked and you'd need to replace this, as if it is locked, it cannot be reformatted.

The last choice is a bit "touch and go" It may work.. it may not. I've used this on a similar laptop and it worked for me, however, this is at your own risk. At 4 years old I'd be getting a new cmos battery before doing this.

Power unit off. Disconnect AC power. Remove battery. Remove the memory cover screw, memory cover and the memory modules. Peel back the plastic sheet from JOPEN1 solder pad. Short JOPEN1 solder pads for 30 seconds. Replace plastic sheet. Replace memory modules. Replace battery. Power up unit. Replace covers if it works.

How do i remove or reset the bios password on an acer aspire 5741


The only way to reset your bios password is to remove your cmos battery. It is a small battery found attached to your motherboard. Most cmos battery is like button cell like this akshay163.gif
If you cannot locate your cmos battery then refer your motherboard manual. If you're computer is using a coin cell battery similar to the above example picture. Removing the battery is relatively simple. use your fingers to grab on the edge of the battery and pull it up and out of the container holding it. Some motherboards have a clip holding the battery down. If your computer has this clip you may need to use one had to move the clip up and the other hand to pull the battery out.
Unfortunately, not all CMOS batteries are removable; some manufactures will only allow a replacement battery to be added. If you're not using a coin cell battery and are not able to determine how to remove it refer to your motherboard or computer documentation for additional assistance in removing the battery or how to insert a new replacement battery.
After removing the battery then replace it.
Your bios password should now have been reset.
Good Luck

Lost password for acer aspire desktop


BIOS Password is stored in CMOS and retained by power provided by the CMOS (Coin-cell) Battery.
To Reset the BIOS Password, Remove the CMOS (Coin-cell) Battery from the motherboard for five minutes and restart the system. This will load the factory default settings and the password would be gone. Re-install the battery after the password is reset.

Hope it helps! Good Luck! Thanks for using Fixya!

Hi i am an indian.sir my laptop toshiba model:satellite A130/A135 Series is asking for bios password.ples help me.


Hi.

If you dont remember the BIOS password, you may remove it by resetting the BIOS password.

Please follow the below steps to reset the BIOS password:

1) Please remove the bottom casing of the Notebook.
2) Once you have removed the below casing, you should be able to see a CMOS Battery.
3) The CMOS Battery will be of a size of a coin.
4) Once you have found the CMOS Battery, please remove and re-insert it again.
5) The CMOS Battery will have the information about the Computer Date, time, BIOS Password etc.,
6) Removing and re-inserting the CMOS Battery will reset these settings, which will also remove the BIOS password.

Please perform the above steps and let me know the results.

Hope this helps.

Please feel free to contact for further information and assistance.

System (BIOS) Password Reset

If you have forgotten your BIOS or system password, there are no software tricks or magical gimmicks that will get the password cleared. Laptops are different in that they are designed to not work with “backdoors” etc. for security reasons. There is one true way that works most of the time and that is hardware.
The Cmos (RTC) battery that is mounted on the motherboard in most cases holds the key, if your motherboard has the battery that is connected to the motherboard by using a two wire socket that plugs into the MOBO, then here is the procedure.
On the motherboard where the battery plugs into, you will see two pins sticking straight up, these engage the plug on the battery side. These two pins have to be “shorted” and then the motherboard powered up for approx. 30 seconds, then power down the system and replace the Cmos battery and reboot. Your password problem should be cleared up. The best way to “short” the pins is get another cmos battery and cut the wires from the battery part, bare the ends and twist together, this will short the pins. Make sure you tape the connection good on the jumper you just made….don’t want to touch anything else with powered up bare wires. Good luck.

I presume this is the CMOS or BIOS password.
Turn the unit over and find the ram cover, remove the ram locate the two brass bars near where the ram was. Take a paper clip and bridge them to short out and reset bios password.

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 .

Default bios password toshiba satellite a135-s2276


what you need to do is pull both the laptop battery as well as the cmos battery. in some instances, the battery can be pulled, but on other models, i have seen the battery as an actual physical part on the motherboard or somewhere where it is not easily accessible, in which case you need to clear the cmos by using a jumper on the motherboard, since it is a laptop, they are all different. you may need to see if you can locate a copy of the motherboards schematics and go from there.
