Replace rtc battery

Lenovo ThinkPad Edge E320?

I don't think you are referring to the Main battery......

However;
1) There is a slide button on each side of the Main battery.
Both are slid to the outside edges of the laptop, then the main battery is slid out. Out towards the outside of the laptop.

I believe you are referring to the CMOS battery.
Also known as the RTC battery. Real Time Clock battery.

From what I can see the ThinkPad Edge E330 is VERY similar to the ThinkPad Edge E320.

What you need is the HMM. Hardware Maintenance Manual,

http://www.manualowl.com/m/Lenovo/ThinkPad-Edge-E330/Manual/309892

Use the Right Arrow on the right side of the number 100, at the top; to go down through the pages.

Page 61 for Main Battery Removal/Replacement
(Starts on Page 60 - 1010 Battery Pack. Bottom of page)

Page 70 for RTC Battery Removal/Replacement
Bottom of the page - 1070 Backup Battery

As you can see you just remove the screws, (Philips. Use No.1 Philips screwdriver, or equivalent Jewelers screwdriver), for the Bottom Cover, and remove the Bottom Cover.

(It's a panel. It is not the Base Enclosure/Bottom Cover)

Then unplug the small white male plug connector, on the end of the RTC Battery's wires; from the motherboard.
Remove the RTC Battery, and replace.

This shows you in a video, but a different Lenovo ThinkPad Edge laptop.

Principle is still the same,

KNOW THIS HOWEVER........
Your body carries Static electricity. When that Bottom Cover is removed, all of the Static shock sensitive hardware components are exposed.......

You need to make SURE your body is relieved of Static, BEFORE reaching to unplug that RTC battery, or remove it.

Better still is to wear an ESD wrist strap, and have it's alligator clip attached to a good ground source.
(Electro Static Discharge)

Average cost is around $3 to $6.
Here is but one example,

Example of RTC Battery,

http://www.ebay.com/itm/COMPATIBLE-Backup-RTC-CMOS-BIOS-BATTERY-CR2032-FOR-IBM-Thinkpad-02k6541-/251250253852?pt=Laptop_Batteries&hash=item3a7faea01c

Now I did NOT state that this was THE RTC Battery you need.
Just stating that is what it looks like.

Know this;
ALL of these batteries produce 3 Volts DC.
They use a CR2032 watch type battery, that is commonly used in a desktop computer.
All you need to make sure of, is the Male Plug Connector is correct.

Yep. That's it.........
If you HAVE to, you could cut the wires on the new RTC Battery, cut the wires on the old RTC Battery, and PROPERLY splice the old RTC battery's male plug connector to the new one.

Use heat shrink tubing, and solder the wires together.

Remove RTC Battery to reset a password?
Nope. Don't think so.

There should be a capacitor, or capacitors; that store a small residual charge of power -> INDEFINITELY, even after removing the RTC Battery. (CMOS battery)

CAN I be wrong? Yep. Depends on manufacturer, and year made.

Replace RTC Battery because it's no good?
Yes. Sure.

Looking at the Base Enclosure, (Bottom Cover), is part of what makes me think the E330 is very close to the E320,

If the notebook you are servicing has an unknown password, follow these steps to clear the password. These steps also clear CMOS:1. Prepare the notebook for disassembly (refer to Section 4.3, "Miscellaneous Plastics/ Hardware Kit," for more information).2. Remove the real-time clock (RTC) battery (refer toSection 6.24, "RTC Battery," for more information on removing and replacing the RTC battery).3. Wait approximately 5 minutes.4. Replace the RTC battery and reassemble the notebook.5. Connect AC power to the notebook. Do not reinsert any battery packs at this time.6. Turn on the notebook.All passwords and all CMOS settings have been cleared

Download this service manual to assist you to locate the RTC/CMOS battery.

You can get the RTC/CMOS battery from this WEB site.

bad RTC can be repaired. the machine is equipped with multiple sensors inside. if one of them goes bad, or the Battery is dead tampering or bad RTC will show this can be fix by replacing the sensor and or the battery if you need this to be done call me @ (775) 358-2922 hope this help : - )

You can try reseating the RTC battery:

Real-time clock battery removal Before you begin: Remove the battery and keyboard.

1. Disconnect the RTC battery cable from the system board
2. Use a small, flat-bladed, non-conductive tool to flip the RTC battery out of the socket on the top cover.

Real-time clock battery replacement

1. With the positive (+) side facing up, insert and press the RTC battery into the socket on the top cover.
2. Reconnect the RTC battery cable to the system board.

If this does not fix the issue, you may have to replace System board

Battery is usually located on bottom of laptop usually takes 1-4 screws to get it out.

There are usually 2 compartments on the bottom, one for RAM memory upgrades and the other compartment is the battery.

you cant reset the bios like that if you upgrade it wrong you need to get the chip replaced or flashed if it can be .it has to be done properly and professionally

Hi, try this:
- unplug from mains
- remove laptop battery
- remove real-time clock (CMOS) battery.
- wait 5 minutes
- replace the RTC battery and then
plug in - without the laptop battery.
The laptop battery cannot be present
when you remove the RTC battery
and shouldn't be there when you power on.

Hi AshishB, Yes, Toshiba does refer to the CMOS battery in their literature as the real time clock battery. Your retailer is half right, the battery is on the motherboard but its attached via a connector and it can be replaced. Here are links to a couple of venders that sell the RTC battery for your laptop: - Http://www.sparepartswarehouse.com/Toshiba,Satellite,L15-S104,Laptop,Batteries-Backup-RTC.aspx - http://cgi.ebay.com/Toshiba-Laptop-motherboard-battery-cmos-L15-S104_W0QQitemZ170060189842QQihZ007QQcategoryZ3666QQrdZ1QQssPageNameZWD1VQQcmdZViewItem Let us know if you have any other questions and please don?t forget to rate the posting.
