Re: Old HDD won't image

I've had really bad luck with those USB adapters. As in "loss of data" bad luck. I'm imaging a drive as we speak with Norton Ghost. It's NOT fun, and it's slower than molasses, but I'm doing it inside my 755C. I would suggest for reliability, and if possible, to image it in an older machine with a r...

Re: ThinkPad 300 2615

Good question. I have about 1 or 2 of these that I need to refurb and sell. I bought my first 300 around 1997 for like $40 on ebay, with a cracked LCD. I eventually got another machine with a good LCD (which has since had issues, due to age). I even had Linux running at one time, albeit in CLI only....

Re: Is 600x 650mhz a unicorn?

I own two 650MHz PIII 600Xs, though I've been meaning to refurb and sell some 500MHz 600X systems.

The speed allows me to use Windows XP to use more "modern" software on them.

Re: 701CS for sale

Someday Bill, I might even get mine working. My 701C has issues in the LCD, but my 701CS works. My big hurdle is replacing the CMOS battery, and rebuilding some actual packs (I have only 3 to work with).

Re: Is it possible to read 5.25" floppy discs with a 770?

Re: New 701C owner, Questions, insight and opinions?

Makes me wonder what those floppy/cable assemblies are worth, as I recently came across several of them. I still have my 701s, though from what I remember, they had corrosion issues, and I really need a battery to rebuild so I can use it off AC.

Absolutely, ask any questions you wish. I personally don't like the rounded corner 755C(x) packs, because 98% of the time, they've leaked. Like REALLY BAD! NiMH packs for the 760 series seem to be in a lot better shape. Some 755CX, CD, CV and CDV systems have an extra terminal for a Lithium Ion batt...

Re: 750C HDD doesn't spin up

I hope you're using a spot welder and rebuilding the battery pack exactly how it was before. Once you get that working, you'll have no problems updating the BIOS. Just make sure you fully charge and discharge the battery once or twice before you really start using it!

Wondering if any would be interested in purchasing rebuilt batteries. So far, batteries I have successfully rebuilt - 755, 755CE, 760, 560 and 600 primary. The 355/360 is the same as the 755, but without the intelligent circuitry. Unfortunately, the most expensive are the 360 and 755, because the co...

Ugh. I was interested in the no power 755CDV, until I saw the price. Technically, I already have one. Combined the LCD from a non-working CV with parts from 2 CD's. I also have the non-existant 755CDX (800x600 on a 755CD). Given it's a no-power machine, is the price negotiable in the future? **EDIT*...

Re: Replace 755CSE LCD with 755C LCD?

If you really want to have fun, find yourself one of those rare/elusive 755CX SVGA screens. I replaced the system board on a dead 755CD I got on ebay recently; in the process, I also swapped LCDs with a SVGA from an also dead 755CX. The LCD has some vinegar syndrome, but for 800x600, I can live with...

Re: mysterious battery on 755, 770, etc

The NiCAD battery y'all are describing is the standby battery. It ONLY handles keeping the memory state intact when you suspend so you can swap main batteries. It has NOTHING to do with 161/163/CMOS. That's handled by the VL2020. Yes, it is rechargeable. No, you cannot use a CR2025/2032 (unless you ...

Based on what's going on, I'd say the system board is bad. It sucks, since your other board doesn't put out video. I know it might not be an option, but there is a PCMCIA boot, where you can use a compact flash card as your boot up device. I don't remember if this is limited to 512MB or not, since y...

I thought all ThinkPads are center negative? Now You're going to make me look at my bricks. And I could be wrong, but AFAIK, the ThinkPad 510CS should work with the same PSU as a 701C/CS. I check next time I'm in my attic, where my 510CS is.

No, you cannot. Just replace the 17500 cells with new Panasonic cells. To use NiMH, you'd need to source an NiMH pack, which uses a Sanyo HR-AUL, or any other 4/5A NiMH.
