    This is Vijay and have the TP 600E related problem on the site.
    Now here is a run down of my situation:

    Just like many out there I have the
    Error code 00174
    DEU 001
    Error 91
    FRU 3610
    appears to be very common but workable problem I'm about to follow some of the advice out there and see how it works out.Meantime any input on the Bttery Pack cost and retailers?Looking for one in Canada..South-western Ontario?Pls help secure peace of mind..

    On the start up there was an error code 174 (started about Sept 21st)
    Investigating the same thru self diagnostics found additional error msg ?
    DUE001 and 91 and FRU3610.Also High Voltage and Battery too hot.
    Research indicated errors relating to Battery Back up CR2025
    Further research /advice indicated remove CR2025 and restart
    Followed up and error codes were gone but 174 continue to be there every time
    Restart generated 174 again and directed to error diagnostics again
    Reinstalled CR2025 and battery pack 02K7018 reset the clock and date.
    Running the test various times(including the loop test)even after reistalling the earlier removed CR2025 and 02K7018, all tests come out OK
    Continue to get 174 on every star-up? including start-up from F1
    Error code refers to confugration related problem?System Board tests came-up OK.
    Do I need to replace CR2025 with new battery and/or battery pack 02K7018(That is an expensive proposition for some one on a budget)
    Do I need to reload the operating system that may clean up the confugration problem?
    Your input and early help will be much appreciated.
    Many thanks in anticipation.( sorry but UR e-mail was rtd undelivered.)
    Yes after you remove the battery the error codes are gone and test will indicate OK for all aspects of testing but still have problem with error code 00174.Advance/loop testing fails to indicate results for HDD?Error code 00174 relates to confugration ?
    Any suggestions/advise?

Errors 161 and 163 mean the time and date are not set in the CMOS. This typically means the CMOS backup battery is dead / going dead.

Starting ibm 600e

Hi there.
Errors 161, 192, 163.
All three of these errors are connected to the back up battery.
To resolve this problem:
1. open memory flap on base of laptop (small philips screwdriver required)
2. find the small connector with 1 black & 1 red wire coming from it.
3. disconnect above connector and gently pull the Red&black wires. The backup battery should just pull out from under the casing.
4. get replacement battery. Either
a. call IBM spares (07900 247 490 in UK) and ask for FRU:
02K6502. UK price is about £8 + £15 delivery + VAT.
b. if comfortable with soldering iron: Carefully open the packaging on the backup battery using a sharp knife.
Remove the solder tags from the battery (these are spot welded so need to be cut/broken off). Buy a new CR2025 battery from any computer shop, jeweler, or camera shop.
Using electrical tape, insulate all round edge of battery
Solder the leads onto the new battery - note polarity. Red wire to +, black wire to -.
Using more insulating tape, wrap battery so that all exposed metal is covered.
5. put new battery into laptop (reverse steps 1-3)
6. start up computer, error 192 has gone, but still shows 161, 163. Select OK.
7. reset date & time, and OK
8. when screen shows 'O / I' restart laptop using on/off switch at side.

Good luck and thanks for using FixYa!!

Boot sequence

161 and 163 error means you have to change your CMOS battery. open the laptop, change the cmos battery and you should be able to set the date and time.

after which you can access the bios by pressing F1 upon boot up and change the boot sequence after that

ibm thinkpad does not boot My IBM Thinkpad 600 (Type 2645-310) stops and hang during bootup. What happens is: 1. LED test, then green Power on and orange battery/charging 3. RAM OK (Responds when I take out /put in different amount of RAM and displays correctly. I have 128 + 32 removable, + 32 internal not possible to take out) 2. I can hear fan, CD drive and evt diskette drive. If I use diskette drive the LED wil give 1 blink, if I use CD drive it will give 14 blink. 3. No cursor seen, but this is displayed: Upper left show the amount of RAM present: 196032 KB OK Upper right IBMs logo in blue; IBM Lower left shows "ThinkPad(R)" in large letters and red dot over "i". 4. Then a "rrrrrr" sound from the loudspeakers after a while, this is in fact 28 clicks shortly after each other. Then nothing more happens. Diskette and CD drive is OK (But can not be used because bootup is never finished). I hear CD speed up and then down again but nothing more happens. No effect in booting with bootable diskette or CD, "Live Linux" CD or else. Backup battery OK (3V) and if I take it out I will be asked for correct date and time when Power on. I can then use keyboard or TrackPoint to set date and time, and after that hangup at the usual point. Starting without battery, HDD, CD drive and removable memory sticks makes no difference in symptoms. Pressing and holding F1 before and during poweron and startup (in order to enter BIOS and selftest) has no effect. I could not find help on IBMs home page, but maybe I did not look at the right place. Is somebody able to help me?
