For clarity, this a circa 2013 model P19E, which I'm assuming is what folks refer to as the Alienware 18.
Keyboard/logo lights up, no video/POST, eventually a beep every second or so continuously. This seems to have occurred spontaneously, during normal use, NOT a CMOS settings or h/w change.
I sincerely believe I've tried every permutation of the standard bricked BIOS procedures, ie removing batteries, ram, cpu, gpus, power button 30 seconds, shorting CMOS battery, hot swapping one SODIMM during the reboot window, etc.
What I HAVEN'T tried is a different CPU, don't have one.
The mobo isn't completely dead, ie the core logic knows whether there is ram, a cpu, etc installed and beeps appropriately.
If there is way to 'blind flash' this thing, I haven't been able to find it.
Here's the questions: Has anyone successfully resurrected one of these with the steady beep every second symptom by attaching a CH341A to the BIOS chip and flashing it with something stock/safe?
Conversely, any value in buying one of the 'pre-flashed' BIOS chips from ebay and soldering it on?
Is there anything less drastic anyone can suggest before I get medieval on this thing?
There so much more info out there on the M18 series, P19, not so much. I hate to give up on this beast.
Thanks for reading.
