Question about IBM ThinkPad 380ED

161 and 163 errors

As the other people have suffered, I am having the same issue with 161 and 163 errors leading me to reset the date/time before rebooting to the same errors over and over again. However, I had seen somewhere that it might be a CMOS battery issue. Does that sound possible? I also know that these days it isn't easy to find a replacement for that old of a model. Do you feel that it's worth trying to boot the system from a Windows OS disc, or is that pointless for this type of error?

    I too have the same problem. This 380 ED worked fine until last week when suddenly I started getting 161 and 163 errors. I reset the time and date and replaced the back up battery. The regular battery has been dead for years. To no avail. i still keep getting the errors. Holding down F1 while I boot up makes no change. I don't get easy start up. I tried running the emergency reboot disk while it was on showing the error but do dice. It didn't read it.

    Can anyone help?

SOLVED! I had this problem with my Thinkpad 380D and FIXED IT.

Take a small screwdriver and open the panel on the underside of the computer, right above the big battery pack area. Inside you will see a watch battery sitting in a little round plastic cradle. The battery pops out easily with a small screwdriver. Buy a new battery at an electronics, radio, or jewelry store. You can bring the old one in to match it to a new one. Mine was a CR1220 and cost $5. Pop the new one into the plastic cradle, replace the panel, and turn your computer on. Now, after you reset the time, the computer should boot normally. This worked for a 380D. Don't know if it would work for other models.

No soldering, no expensive replacements, no special batteries needed.

Thanks for sharing.
I had the same problem with my Thinkpad 380ED.
I tried to remove the little battery like you suggested with a screw driver but it wouldn't budge. Gave it a bit of elbow grease and the round plastic cradle snapped! Still intact but you can tell its fractured. I suppose I will use a bit of sticky tape or something to wedge it under the lid. Anyway, I will get the battery tomorrow. Hope everything works fine.

I have another question and hope you can help.
How do I connect an external MP3 or MP4 device to get it to sync with my Thinkpad?
Do I use the PS2 outlet where you would plug in the external mouse?
Is it possible to get it to sync with these new devices?
Thanks for your help.

I hear 4 beeps ever 5 minutes on my emachine et1331g

That is somewhat odd. I don't think that I've personally heard of that happening before. Question: What is the date/time on your computer? I ask this as I believe that your issue may have to do with the little battery on the motherboard.

If the date/time on your computer gets reset every time you turn on the machine then you'll want to replace the little battery on the motherboard.

It's a bug issue in the firmware of the R4 cards. Won't work after 14 april 2010 unless you update the firmware of the R4 card.
For the time being you can set back the date before 14 april 2010 and it wil work directly.

I have several 600's and they all have the same issue. They are giving 161 192 163 errors. I replaced the battery in them and then go to try and setup the time. However, instead of letting me set the...


161 = CMOS configuration lost (battery has died).

163 = CMOS error; Clock is not updating.

192 = System fan is faulty, not plugged into the system board or the system board itself is faulty.

Whe you replaced the RTC (real time clock/BIOS battery) did you make sure that the CPU fan was working?

If it is then go back into the BIOS and reset it to defaults. Save the changes and reboot, then go back into the BIOS and try to set the time and date.

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.
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

Needs factory reset or master reboot


your question is very basic.
if you need to master reset the system to it,s bios default settings.
remove the power, remove the left hand side panel. locate the cmos battery.
remove the battery for 10 seconds, then replace it. replace power lead and reboot.
if you get a message stating cmos settings incorrect, enter bios setup. change time/date settings.
save and exit. Problem Solved.

sounds like your cmos 3 volt battery is dead and needs replaced.
its a very small coin size battery located/hidden inside the laptop.
you will have to google the placement or just find it.
