Greetings chaps (and ladies),

I'm having a weird issue with my X61s since I changed the memory to give my friend a 2gb stick & left myself with two matching pairs pc2-6400s 1.8v modules. Now the Laptop did boot for a while & I thought all was well, then it stopped turning on. All I get now is the Green power circle with a Z in it, the batter & mains addapter led. The Hard Drive spins up & if I leave it on a for a while I can feel it heatting up, but nothing on the display at all. I've connected to an external montor still nothing...even changed memory that is known for working

Any tips? Or shall I just turn it into x61s spare parts ?

Cheers all.

If you remove all memory, it should beep 1-3-3-1.
Check that and report back please.
The PC2-6400 RAM might not be compatible, try PC2-5300 instead.

try re-seating the SO-DIMM. Take out one module and boot with the remaining one and see

RealBlackStuff,

Tried using memory from a working T62P (PC2-5300) but still not working, same issue. No beeps at all with memory in or out?

Also tried reseating the memory.

Time to break for parts?

Ask the RAM back from your friend, and let him get other RAM.
If that still doesn't work, look for another motherboard.

thanks RealBlackStuff for the advise, will attempt to get the memory back and test.

However should I not be getting some beeps?


Cheers.

No RAM: should beep 1-3-3-1.
If no beeps, normally bad mobo, but try the old RAM, just in case.

No beeps...so news mobo. Thanks again for your help and advice.

try unplugging the bluetooth cable from the motherboard. oddly enough, when I did that with an X61 tablet, it started working fine.

Have you removed the battery and the AC Adapter and then re attached,
sound like the machine is stuck in a sleep mode
