I have an XPS14 L421X which when starting up will beep continuously and not show anything on the screen at all. It is a short beep followed by a long pause repeated over and over and this is continuous. After turning it off then on again 5-20 times it will eventually boot up properly.
I've tried removing the battery, reseating the ram etc.
Looking at the beep codes it looks like a bios or system board problem but could someone technical elaborate further and give me some advice on how to fix this issue?
Thanks.
