It's the memory modules. If you have more than one memory module in your system, try to remove one of them and see which one works.

E320 2007 battery replacement


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,

http://support.lenovo.com/en_US/downloads/detail.page?DocID=PD021754

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,

http://www.radioshack.com/product/index.jsp?productId=2103245

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,

Rtc battery is low or cmos checksum is inconsistent


The RTC battery is a rechargeable Li-ion "clock" battery that's buried underneath the keyboard - it keeps date and time going when your computer is turned off. If you're getting this message, you should go follow the screen prompt, hit F1 to enter Setup, and set the date and time, leave the computer on for several hours to charge it (the clock battery recharges only with the computer turned on) and it should go away.

In the rare event that your RTC battery is bad, it's really up to you as to getting it replaced or not - it's a lotta work, and not all the battery vendors out there is competent enough to sell you the right kind of battery (installing a non-rechargeable Lithium battery will kill the thing outright, and there are actually people selling these....). Not having a working RTC battery doesn't really interfere with the workings of the computer - you'll just have to set date and time every time you start it, and you can do so manually or by downloading some freeware such as Atomic Clock Sync to automatically do it for you.

Bad rtc chip please reboot


RTC is the Real Time Clock or the Modem within the terminal. This error means that the device is failing and would need to be replaced at some point. To resolve you would need to powercycle many times in a row until the screen with show "TAMPERED", then it will go to the Sale, Refund, Void screen and you can run transactions. This error will arise in the future. RTC error cannot be resolved for good. Thank You!

Dear sir/Madam can you please help. Ihave just built my pc. MSI P35 DIAMOND.but when i turn it on i get a red light on whuch means.testing RTC (real time clock) so i cannot get in the bios or anything....


It has to test the RTC before it can do anything. If you turn of the computer while it is testing it, you risk damaging the RTC so you won't be able to ever boot up. It will only boot if the RTC test returns a non-corrupt RTC.

I get the message "Bad check sum (CMOS)" Model toshiba tecra 730XCDT


hi friend,

Probably a dead Motherboard battery. Need to enter the BIOS screens and reset values. Especially the time and date. Maybe the boot order and if using USB KBoard enable legusy USB devices. This will occur each time your friend shuts down and reboots until the battery is changed.
Issue
When you turn your Toshiba computer on, you see an error message like: **** Bad RTC battery ****
**** Bad Checksum (CMOS) ****
Check system, then press [F1] key The Real Time Clock (RTC) battery provides power for the internal clock/calendar and for maintaining system configuration settings.
This error can occur when a machine has been left turned-off for an extended period of time (around a month), and is the result of a depleted RTC battery. Other symptoms include not being able to execute Windows Update properly, errors/problems executing application software (like Norton Antivirus), and the appearance of the Windows XP "Desktop Clean Wizard".
Resolution This condition is easy to fix in 3 basic steps: Reset the BIOS defaults
Set the correct date and time in Windows.
Charge the RTC battery Please follow the detailed instructions in the next section.
Procedure Set BIOS defaults Press the [F1] key as instructed in the error message:
**** Bad RTC battery ****
**** Bad Checksum (CMOS) ****
Check system, then press [F1] key In the BIOS setup screen press the [Home] key to restore the default values, then press the [End] key to save and exit, then the [Y] key to confirm and restart the system. Set the correct date and time in Windows As Windows starts-up, you may see an error message about an "Invalid System Time". Go ahead and click "OK" to clear the error dialog. Open the Windows Control Panel and open the "Date and Time" control by double-clicking its icon. Set the correct date and time, then click OK to save. Charge the Real Time Clock (RTC) battery To charge the RTC battery, connect the AC adapter and turn the computer on (both the DC IN and Power LEDs must be green). Leave the machine on for approximately 24 hours to ensure a full charge in the RTC battery. Please note that the RTC battery does not charge while the PC is turned off, regardless of whether the AC adapter is connected or not. Other Information: If, on subsequent reboots, the "Bad RTC Battery" error persists, it's quite likely that you actually do have a bad RTC battery. If that's the case, you should contact a Toshiba Authorized Service Provider to have the system serviced. Windows XP Desktop Cleanup Wizard The first time you reboot Windows XP after resetting the system clock, Windows XP may try to run the "Desktop Cleanup Wizard". Simply Cancel the "Desktop Cleanup Wizard" at the first dialog. If you do manage to clean your shortcuts from the desktop and want to recover them, you will find them in a folder called "Unused Desktop Shortcuts". You can recover them as follows: Double-click to open the "Unused Desktop Shortcuts" folder
Click to expand the "Edit" menu, and click "Select All"
Drag the selected items back to your desktop
Close the "Unused Desktop Shortcuts" folder. You can delete this folder if it is empty.

thank u for using fixya
