    Thank you very much for the advice in sorting my problem. I intially tried a pc133 card, the system recognised it but the win 2000 would not start. I did a search and it came back with the genuine IBM parts which were pc100 the laptop does not seem to like these at all. I was then told to try pc66 as it was thought that this was the bus speed. I have yet another card coming today which is pc 133 but a of different manufacture and intend trying that. failing that i think it may be destined for the great laptop recycling unit in the sky.

    Kind regards

    Thanks again for your advice and patience,

    The laptop is aTYPE 2645-4AU IBM 6600E notebook

    The sticker from the 32mB installed says IBM 38L2974 1N7GL S/N 0 BLD27 FRU 42H2819.

    I have sourced pc 66 ram at good money. $44 for 128mb

    Would going to win XP make a difference I have os version.

    The pc 100 genuine IBM ram I got on advice for it has the following 11S01K2730ZFPD8J1CU082 FRU: 20L0265 OPT: 20L0255 3.3V (16Mx 64) on it

    Once again thank you for your time and advice most appriciated

    Kind regards

For this amount of RAM, the operating system should not be an issue. You may have a compatibility problem w/ the RAM you are attempting to use.

Below is some info. I gathered on your system and its memory requirements. Hopefully, this will help.

Whenever you're looking for memory for a computer, a good search to use in your favorite search engine is "memory configurator". A number of manufacturer's have a place on their web site where you can plug in info on your computer and find out what RAM it supports, etc.

Your system can support up to 288MB of RAM. 32MB is fixed (built in).

That leaves you w/ a maximum of 128MB per bank (slot in this case) for a total of 256MB max added.

Your system does not require ECC nor dual channel memory. Nor do the DIMMs need to be installed in matching pairs.

Your system takes SDRAM. PC133 will be fine. In fact, you'd have a difficult time finding PC100 these days (and it'd be a lot more expensive (because it is essentially obsolete technology).

Please, go HERE for IBM/Lenova's listing of memory options for your laptop.

Please, let us know if this response was helpful for
you or, of course, if you have more questions, etc on this topic.

Thank you

    You're certainly welcome, Andy.

    That's what I was unable to determine - the bus speed. The memory configurators I checked for your laptop called for PC133 but their not always right. I've used a company called MemoryX (memory 10) online for finding hard-to-find memory. They have good support and a good return policy. You might want to give those folks a try if the DIMMs you have coming in don't work out for you. I wouldn't toss the system over this. You can run Linux or this system very nicely. I'd keep hunting until I found RAM that worked.

    Was/is there a sticker on the RAM currently installed or originally installed w/ the laptop? Can you get any info. off of that?

  • B Joan Rapier
    B Joan Rapier Apr 04, 2008

    You're welcome, of course.

    I would not recommend attempting to run Windows

    XP on 256MB of (especially PC66) memory. You're not going to be happy w/ the computer's performance. That machine was just not designed to handle the load.

    How 'bout trying Linux Ubuntu (or another Linux OS that is easy on resources)? Linux is great for old laptops and computers.

  • B Joan Rapier
    B Joan Rapier Apr 04, 2008

    Regarding the info. you got off the original RAM sticker, I'd hang onto that. If the RAM you have on order doesn't work out, try MemoryX and see if they can get the appropriate RAM for you.

    I have an old IBM Thinkpad, too, whose resources I maxed out. Over the years, I upgraded and upgraded hardware and OSs until finally it choked under the load. Still its the most reliable computer I ever had.

    I've had it on a shelf for nearly a year swearing I'm gonna load Linux on it. I'm a "Windows Head", too but I remember the old days of being a "DOS Head" as well (b4 it was cool to be a "geek").

    Command line is fine, too, once you get the hang of it. And Linux distributions now are by and large GUI (graphical user Interface) driven. There's lots and lots of support, too (forums and such) so you won't be on your own or at the mercy of a conglomerate like Microsoft.

    Be patient and have fun w/ it. I'm pretty sure eve a Scot' can manage Linux. ;>)

    Hello Andy,

    The (FixYa) system for notifying Experts that there's been a Request by an Asker is broken. The link included in the email to view the request is broken. (FixYa support staff is working on this.)

    Is there something I can help you with? Do you have another problem running you'd like me to participate in??

    Just let me know. I'll be happy to help.

    Thank you

    Hi Andy

    So, let me see if I'm understanding you correctly...

    You got the critter working using PC133 still but from a different manufacturer, yes? If that's the case, what manufacturer did you use.

    You're right, this would be very useful information for others to have. It's kind of you to post back here w/ this follow up. It will likely help others w/ the same or similar issue.

    BTW, let me know how you do w/ Linux. I think you're going to like it.

    BJ @:)

    Hi Andy,

    I really enjoyed working w/ you. I do hope you come back.

    I wonder if you wouldn't mind terribly taking just a moment to re-rate my solution to a "FixYa". We experts live and die by our ratings here. A "FixYa" can be a nice way of saying "thank you" to an expert who stuck w/ your problem and continued to work w/ you and dialog until it was all sorted out.

    Thank you so much,

    BJ @:)

I upgraded to 512mb 144 pin in memeory slot

Take the RAM out. Will the computer boot?
Put the "old" RAM back in. Will the computer boot?

Some laptops are _very_ "picky" as to which 144-pin RAM is compatible.

Did you do your "homework" when buying the 512MB stick, to get compatible RAM?

Formatting IBM Thinkpad 600E

I know you can't boot from the Windows 98 CD, and probably not from Windows 2000 either. It is possible to turn the the Windows 98 bootable floppy into a bootable CD, but I think you would be much better of trying to install Linux.

Probably the display driver is messed up. Best option is to reinstall the operating system.

An alternative is to have a Linux-savvy friend try to boot it up
with a Linux-live rescue CD to see if that fixes the display problem and maybe to salvage your personal data from the hard drive.

Do a search for memtest86.iso. Burn this image to a cd and reboot your computer. When your computer reboots it should begin checking your memory for errors. If you still have problems it might be your hard drive.

IBM Think Pad T22 auto -shut down a few minutes

Try running it without the battery. Sometimes an IBM battery can develop a short and cause this. If it still does it without the battery, I'm afraid it's the power management chip on the motherboard, and the motherboard will need to be replaced.

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?
