Re: 701CS - CR2032 (non rechargable) - safe to use?

0.2V is idealistically high, assume 0.5 minimum, closer to 0.7.

Use 3x 1.5 LR44 and a 0.7v silicon diode.

Re: 701CS NiMd/NiCd - does it matter?

Haha stop doing so much paper to paper comparison. In 99.9% of situations, NiMH will behave identically to NiCD. The exception is with dumb-charging, which the 701CS is almost guaranteed to not be using. This was phased out by 1990 in most laptops. Don't worry, both NiMH and NiCD are pretty bulletpr...

Re: 701CS replacement battery - dimensions / 3D model needed || ((or source for original battery shell))

I have a battery I can make a model. Also: these old laptops are *VERY* finicky about the ESR of the power they're supplied with. The battery must be spot welder or soldered together or it will not boot the laptop. Also should be good for about 8-10 amps PEAK power and 2 amps continuous if you are g...

Re: Possible for a laptop to be compatible with a Pentium II and III at the same time?

Ah I didn't know about the T420 Ivy-lock. Oh well :??: .

Anyway thats possible, given the speed at which CPUs were progressing at that point, it was likely easier to grab a new chipset and throw some older hand-me-down CPUs in it and call it a consumer machine.

Re: Possible for a laptop to be compatible with a Pentium II and III at the same time?

FWIW I believe that Putting P3 chips in a 770X was common, and that was a P2 machine with the MMC2 socket. If it can go forward, I see no reason it can't go back as well. On a more modern note, T420 could take a 3rd gen processor and same for the T430 for the 2nd gen. Should be okay to go ahead.

Re: ThinkPad T530 with Nvidia GPU: High CPU Usage

I5-3230M is not the fastest thing, although should be capable of it. Why is your CPU running at only 1.2GHz though? It might be pegged because it's not going full speed.

It's got a 1 lane LVDS connector, 1366x768 is the max you'll get out of it. Also, you don't have an onboard DP connector to scavenge the signals off of, your sore out of luck there.

Re: W10 x86 LTSC installation on X60s

Use the W10 USB creation tool and try again. It's the dedicated one from MS and IMO the only one you should use.

EDIT: I guess that's what the Media Creation tool is called. Also check in the BIOS compatibility vs. AHCI mode.

Re: Bought a T450s with FHD Panel. Can anyone identify the problem with this screen? Stuck pixels?

IMO, your kinda stuck. It looks like panel damage. Your best luck is to see if pressure/release makes it go away. Also you could look up a stuck pixel tool that flashes colors rapidly to make the pixel work again. There are videos on YouTube to do pixel "treatment".
