Won't power on beyond a blue LED flicker and fan kicks a little
So i’ve been through all the basics, the ESC+RESET+POWER, unplugging the display screen, unplugging the battery and holding power down, and I’ve let it charge to %100 (from orange to solid blue). I’ve tried the 60 second power button holding down and no joy.
From the teardown i’ve seen, it doesn’t have a standard BIOS battery, just works off the main battery. It’s using a SSD 16GB and i’ve not yet pulled that. I could be wrong, but i think the memory is onboard as well as all the upgrade sites just show the C720 and not the chips or speed. Heck, i’ve even taken the “lock” screw off to see if that would cause anything different.
Any ideas on what it might be?
Add to original post: It’s not coming on. No solid power LED, no fan spinning. So any advice about doing things that only work with the power running won’t really help. Suggestions for procedures (that require it being on) really are not relevant.
I forgot to mention i tried connecting it to an external monitor when i began diagnosing it.
Questa è una buona domanda?
