Omen HP 870-270
Microsoft Windows 10 (64-bit)

Hi - I added a new monitor today and this beeping problem has started. When the the system is switched off and the new monitor is connected (via DisplayPort), I power up the system and the PC immediately emits 3 longs then 3 short beeps, and keeps repeating this.


My video card is fine, because I already had two other monitors connected (one DP, one HDMI) with no issues.


I found the following support page re this exact issue, however they refer to the Omen HP 875 desktops not Omen HP 870:


I just updated the BIOS to the latest version (from the Omen 870-280 page here:,  however the beeping issue is there.
