My XPS 8100 beeps 3 times on boot and don't go any further.
I have to force shutdown and retry several times to get it starting, or to "shake" something inside : memory, graphic card, CPU fan plug. Sometimes unconnecting and reconnecting mains plug is a solution too ...
Once started, this machine works perfectly well but booting is always a problem.
I haven't found a list of the beep codes for this model. What do those 3 beeps mean ? (slow beeps)
Thanks for helping
