T500: "It's Dead, Jim!"

#1 Post by ArtShapiro » Tue Oct 15, 2019 10:19 am

I was sitting with one of my T500 machines on my lap last night, happily working away, and it suddenly went stone dead.

Now, from either battery or AC, I can only get a brief flicker of the lights when restarting after the multiple power button push technique.

I suspect this guy has breathed its last, but it never hurts to ask if there's something obvious I can do. I'm not sure it is even worth pulling it apart to see if there's anything obvious to a layman.

Begin with removing the RAM, then try to start.
If it still beeps 1-3-3-1 then there is still some life left in it.
Lovely day for a Guinness! (the Real Black Stuff). And pigs CAN fly!

I've also seen bad batteries prevent a ThinkPad from booting. Have you tried leaving battery out and boot on AC only?

Thanks for the replies, folks. As per my post, I had tried both battery and AC-only.

I'll pull the memory a little later in the day, and report back if it gives me the mem beepcode. UPDATE: Negative - no change with memory yanked.

Remove HD, CD and wifi card. Try on AC alone.
Also swap CPU, try again.

Something power-related on the system board may have gone out. Good thing pulled boards are plenty and inexpensive, if you want

Well, this one has floored me.

As per the suggestion from RealBlackStuff, I pulled the HD and DVD, and for good measure the CMOS battery. Didn't (yet) pull the CPU as that's a little more of a nuisance.

Upon putting things back one at a time, starting with the CMOS battery and one stick of memory, I was astonished to have it come up and to boot successfully off a bootable thumb drive.

After picking my jaw back up off the floor, I put everything else back. It's working fine and I'm typing this reply on it.

We'll see if it lasts the evening. I am pleasantly baffled. I'm not using my four T500 and W500 boxes very much after jumping ahead ten years to a couple of X1C5 machines two or three months ago, but I hate to see them just die for no particular reason.

Art, agape

Maybe you cleaned up your T500's version of the ENIAC's "bug".

I like the T500. It was and 10 years later is still a nice platform.

I agree. I've upgraded mine to the specs I wanted above and beyond what Lenovo envisioned for these machines and it is still a stellar performer heads and tails above i3 and i5 machines of just a few years ago. Especially those sold at Big Box stores.

You do use a linux live usb to test I hope? Just to rule out a crashed microsoft OS. You can access bios? Use external monitor, etc...


edit: you solved it meanwhile, good job :thumbs-UP:

Thank you for the suggestion, but it never got remotely far enough to worry about the OS. The bleedin' machine wouldn't even begin to come up.

It's still working fine after a few days. Maybe it was the proverbial "carbon on the valves."
