How to remove CMOS battery for A215-S7444? I done a search and got this answer: "This should help: * Remove Laptop Battery * Remove Memory Cover * Spread spring clips to outside and * pull out RAM memory * Remove clear vinyl label opposite RAM memory slots * In the upper left corner you will see JOPEN1 with a white silkscreen square Opening the cover locate cable red-black coil then pull slowly, CMOS battery cable connecting laptop to board. Then pushpin connect the needle pushpin negative to positive pushpin to short circuit then it will reset the BIOS configuration after then pull CMOS battery with pushpin and return to the initial position." That is for BIOS reset and I don't see any red-black coil on the left corner!. Anyone have solutions and diagram to help. Appreciated.

removing cmos battery doesnt work no matter how long you leave cmos battery out been there done that , you have to locate cmos jumper on motherboard , remove main battery & memory cards , peel back clearish foil on motherboard near where memory cards install , should see jumper points on motherboard , take bread tie touch jumper contact leave main battery out stand up like book plug in power adapter , and turn on only until boot screen then shut-off , install memory card , remove jumper and try starting laptop , if it hasnt cleared password , remove memory cards and try jumping it again

Hi ashisbd

If it is a Password holding you up at POST and the Laptop will neither go into BIOS nor Boot at the POST Screen, then the only way around this is to either enter the correct password of to dismantle it and disconnect and reconnect the CMOS battery inside, reassemble the laptop and then try again (see images below for a typical CMOS Battery Access and a typical CMOS Battery).

In some laptops there is an extra level of security for BIOS Passwords. The BIOS password is stored on a subsidiary chip rather than the main BIOS Chip and disconnecting and reconnecting the battery will not work.

I hope this helps.

BATTERY MOTHERBOARD CONNECTORS

On the computer motherboard locate the BIOS clear / password jumper or dipswitch and change its position. This jumper is often labeled CLEAR, CLEAR CMOS, JCMOS1, CLR, CLRPWD, PASSWD, PASSWORD, PSWD or PWD. To change the jumper remove it from the two pins its currently on so that it covers the pin that is not covered. For example, in the picture to the right pins 1 and 2 are covered, you'd remove the jumper and put it on pins 2 and 3.

Once this jumper has been changed, turn on the computer and the password should be cleared. Once cleared, turn the computer off and return the jumper or dipswitch to its original position.

The location of the jumpers or dipswitches are dependent on the manufacturer of the computer and motherboard. However, below are some general ideas on where to find it. Remember that most motherboards could have dozens of different jumpers, make sure you're changing the CMOS jumper and not something else. If these general suggestions do not help refer to your motherboard / computer documentation or skip to the next step.

1. On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.
2. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.
3. By the processor - Some manufactures will place the jumpers by the processor of the computer.
4. Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.
5. Other visible location - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location.

if you forgot password remove mainboard battery for 5 min will clear all passwords

Manufacturers sometime put BIOS passwords to protect system changes that may affect your notebook. To reset the BIOS password read the information from this link.

In case of your notebook the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper and I wouldn't recommend doing it especially if it's under warranty.

How to get to the CMOS battery

The Toshiba Satellite A215-S4747 Notebook PC's CMOS battery, is soldered to a bracket on the bottom of the motherboard.
The laptop has to be completely disassembled to access it.

In this photo showing the bottom of the motherboard, the CMOS battery is in the middle,

This is a link to a free Service Manual, detailing disassembly,

Go to the 11th line down. The one that starts with Satellite A10
Go across and click on A215

This is a PDF file. It may take up to 30 seconds before you see the first page, and additional time to fully download.
Suggest you let the file download all the way before looking through it.

1) Remove ALL power to the laptop. Remove the AC adapter (Charger) and Battery

2) Observe Anti-Static Precautions
Suggest you bu and wear an ESD wrist strap, and connect the alligator clip to a good ground source.
Average price is around $3 to $6.

3) Use a multi-compartment container for the various screws you will remove.
Mark each compartment for the area the screws come out of.
There may be as many as 60 screws and 12 different types.
Do Not mix them up.

(You can use a clean egg carton in a pinch. Mark each egg holder)

remove the battery and replace it with a new one the checksome error is due to the battrrey

You can either find the CMOS backup battery and take it out for a while to let the memory discharge, or look online to find a program which will crack the Phoenix password (these do exist, I had to use them when I was in business fixing computers).

this is option A


- enter BIOS pressing F2 or else while booting,
- change boot configuration :
1st floppy drive a: (if it has one), else cd/dvd drive
2nd usb or network boot
3rd harddisk

- exit saving changes(ESC or F10).
- insert xp or win2000 setup cd and wait if it is recognized and tries to install,
if yes and c:(the harddisk is accessable), youre lucky, if c: isn't. leave the win-setup.(F3)
shut down a total (if freezes, pull the plug, remove battery,)
until no power is sent to mainboard.
you didn't break anything doing so!
and leave it as it is.

THEN!
start worrying about exchanging the c-mos battery(the little flash-memory device on the board that keeps in mind all the system components attached)
( it' a button cell, you'll have to remove some parts to axxess it.)

before doing so, please come back with results of the option A given
