Thinkpads Forum

Dear folks,
I received an almost new, hardly used R60 (...I know, but most folks here are in the T60 section, and T60 and R60 mainboards are almost identical.)

It is a 15" SXGA model with a T2400 and ATI X1400. It looks like new, but one day it did not want to boot. I am still quite new to the T6x series, after 7 years with detailed experience with the T4x series.
My first tests reveiled the following (side by side with my working T60):

Power supply is fine, I push the power button.
All LEDs go on, battery is charging, fan starts spinning. Fine.
Fan then turns off, as it should be.
But there is no beep, no logo on the LCD. Looks like an abort of the power-up self test.

I removed the BIOS battery -> no effect
I pushed the power button and kept it holding for 30 sec -> no effect.
I removed the RAM -> I get the typical RAM Error beeps. So far so good.
I changed the RAM, no effect. I took all unnecessary cards out, no effect.
I checked all fuses I could find, they were ok.

Does anyone have a fuse map, just like the T4x map here in the forum?
Does anyone have a clue what to check next?

Is it possible that the ATI chip might be flawed like on the T4x series?

Any help is highly appreciated.
Thanks,
Beeblebrox

What happens if you connect an external LCD?

I don't have an external LCD available at the moment. Would it boot if it where there?
The notebook does not even beep when turned on.
I searched the internet, but could not find a fuse map of the mainboard.
My impression is that there is a blown fuse somewhere.

I have a T60. It does not 'beep' when powered on. Try an external LCD.

OK
I can confirm, that the T60 with the hot ATI X1400 has a flexing problem.

It is now the third T60 that suddenly had a blank screen on boot-up or did not want to boot at all.
Today I opened it, checked for bad fuses, found nothing and then pressed on the ATI chip. Yeah... it boots and beeps.

But I could not get beyond the Thinkpad Logo, not into BIOS or anything else. It just froze. I pushed several times again, and now the T60 is dead.

Oh well, the typical ATI flexing problem... not again !!! I hoped it was over after the T4x series.
