How to remove cmos battery - Toshiba Portege M200-S838 Tablet PC

I have not specifically worked on this make/model of computer.

Technically, you cannot reset this ... I think what you are asking is how can your modify the settings. Typically one would press F2 or F8 or F11 to enter the setup during the boot process. It may be a different F key, it should flash on the screen when you boot.

You could disconnect the battery back up if you can locate it. ..This will remove any custom setting, but will not let you get back in to change it unless you find the correct F key to press.

On the other hand ... there are no more than 12 F keys. You should be able to find the proper one.

If this doesn't work, you should go to www.fujitsy.com/support for assistance.

Thanks for visiting today.

When you replace the CMOS battery, you must wait about 10 minutes with the old battery removed, before fitting the new one (if you had a problem with the error message before) - when you fit the new battery, plug the tablet in and don't turn it on - this will give the new battery a chance to power up all of the CMOS on the board and settle down. Then turn it on, wait for the error message about the date and time being wrong, set the time correctly and the problem has gone.

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper.



B. By Using Software:


I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Hello,

who told you that the fault was from the Cmos battery? This is a display issue and not cmos battery. Who ever told you it was a cmos battery problem was wrong. The function of the cmos battery does not concern video problem.

Since the fault has to do with video, you will have to check the screen and screen inverter.

Also, does you tablet PC has a space for any external display like motherboard? You can connect it to an external display to see if there will be a display. ( This is optional, if it does not have external display connector, then you cannot do this).

So review the inverter because there is every possibility that the fault is from there.

I hope this makes sense to you.

Good luck.

the COMS battery is part of the motherboard, in most PCs they are inserted in a removable slot, the battery is a watch cell the size of a Dime and can be replaced (the battery serial/model # may be CR2032)
In some they are fixed in the motherboard, it's hard to remove it in this case.
u need to open the PC box to look for the battery, it can be easily detected if you can view ur complete motherboard.

The cmos battery is exactly located beneath in between the touchpad and speaker, it's a meticulous job, you could see a twin cable leading through the keyboard area. After removing the keyboard, cut the battery wires at the edge of the old battery and replace the new sealed pack by soldering its wires to the same connection. Be cautioned not to break off the slim edges of the keyboard sides by attempting to reach the battery while lifting up top silver panel from the front near the Infrared.

Remove the battery on the mother board, wait 5 minutes.

The CMOS Battery is behinf the main battery behind a platic shield. The shield is relitivly fragile and glued around the edges. Care should be used removing it to prevent ripping. The battery itself is 3" flat pack glued to the case. Mine was wrapped in a black heat shrink with two wires exiting.
The connector is under the keyboard. You will need to remove the 6 scres from the bottom of the case to release and remove the keyboard. The keyboard ribbon cable is attached through a ZIF socket. Be sure and release the cable before removimng the keyboard. Youll have to trace the CMOS battery leads to determine the correct connector.
I found a Maxell ML2032 rechargable battery. Unfotunatly all the 3" flat pack batteries I have found are LITHIUM ION and not rechargeable. If I find a replacement I will post the information.
