Caps lock and num lock blinking in sets of three

Contact support for repair due to graphics or video failure.

Specific patterns of long and short blinks along with long and short beeps (where applicable) identify errors during the startup process. Newer computers have two-part blink sequences with different color lights to indicate specific errors. The LED blink/beep sequence near Caps Lock and Number Lock keys indicates the type of error:

  • The red Caps Lock LED blinks are long.
  • The white Caps Lock LED blinks are short. For example, ‘3.5’ indicates 3 long red blinks and 5 short white blinks.
  • On systems that do not have a dual-color LED, both long and short blinks are white.
  • Some systems do not have a speaker and do not beep.

  • @ebrossbluesman3ebrossbluesman there is not a reset. Your computer is telling you there is a hardware failure. Get it repaired or replace it. – Appleoddity Mar 10 at 4:02
