Does anybody have a manual for an IBM external battery charger IBM PN# 2K6500 FRU 02K6501. When can you tell if the battery is fully charges. Does the green light go to a steady green? ANy help is apprecaited.

Thanks in Advance

Yes, you've got it right.

From the manual,

1.
[...]Make sure the power-on indicator [pic] on the control box is on.

2.
Have a battery pack on hand.

3.
Insert the battery pack into the slot of the battery attachment. Make sure the charge indicator starts blinking slowly which indicates that charging has started.

4.
When the charge indicator [pic] stops blinking and continues to stay on, remove the battery pack from the battery attachment. The battery pack is fully charged and ready to use.

Thank for the information. I thought it worked that way, but was not sure.

How long should it take to recharge a battery 2hrs or more.

I tried charging two batteries I have took over 8 hrs until I got the solid green light, but still won't fire up the ThinkPad.

8 hours per battery is way too long, but 4 hours each would be possibly right. The manual says that full charging takes 2-5 hours. In my experience, it seems to charge at about the same speed as if you had the battery installed in your Thinkpad and your Thinkpad was turned off.

If you charged your battery for 8 hours and couldn't fire up your Thinkpad, then I would suspect you have a bad battery, or a bad charger/AC connection.

One thing you might try is to use the battery rundown feature from the PC Doctor Diagnostic Disk, and do a couple full battery rundown/recharge cycles to see if your battery recovers.

Phil,

Thanks for the information. I just got this IBM ThinkPad 600x and I didn't see PC Doctor on the laptop. I went to Lenovo Support & Download page to get a copy of the program for the 600x to load up.

Again Thanks

Phil,

I download the program and used my desktop at work to put it on a floppy disk as it requested. Since I don't have a floppy drive (I have one coming in for it) do you run this program from the floppy drive only from startup? or can you have it reside on the HD ?

Thanks in Advance

If you have a way to burn a CD (and a CDROM drive to boot it from), then try the same PC Doctor program which I put into an .ISO file (CD image file). I am currently hosting that file on my site at:

And to answer your original question... yes, the floppy (and CD) are bootable disks. Simply load them into the drive and boot the system. You may have to change your 600X BIOS (Easy Setup) to look at the diskette or CD/DVD before the hard drive.

Phil,

Thanks I went to your site a downloaded the files on to a CD. I will let you know what comes up.

Thanks again

That's Ray you should be thanking for the Disk Doctor CD download .

And just so you're clear, you don't need the Disk Doctor program to run down your battery: you can just leave your Thinkpad on long enough. But the Disk Doctor battery rundown utility is very efficient at it, and the next time you boot it up from the Disk Doctor disk, the utility will tell you how long your battery lasted before clunking out, so you can accurately track if your battery capacity is increasing during the rundown/recharge cycles.

If you obtained your 600X used, and you do not know the condition of the batteries you have, then I would suspect they are both simply gone bad.

Phil.

Sorry Ray for the mistake, Thanks for the site. I want to thank both of you (Phil & Ray) or your help..
