Common Blink LED Error Codes and their Solutions for Hp Laptops
Let’s take a closer look at some of the most common HP laptop blink LED error codes and their solutions.
- If the battery power LED is blinking continuously, it indicates a battery fault. This may occur when the AC adapter is plugged in and the battery is charging, but it doesn’t have enough charge to run the laptop.
- A single beep or blink at the Caps or Num lock suggests a CPU fault. This may happen when the CPU is not functioning properly.
- Two beeps or blinks at the Caps or Num lock signal a BIOS fault. This could be caused by BIOS corruption.
- Three beeps or blinks at the Caps or Num lock point to a memory fault. This may happen when a memory module is not working correctly.
- Four beeps or blinks at the same Caps or Num lock indicate a graphics fault. This may be due to a malfunctioning graphic controller.
- Five beeps at the Caps or Num lock indicate a system board fault. This may occur when the general system board fails.
- Six blinks or beeps at the Caps or Num lock indicate a BIOS fault due to authentication failure.
- If you notice continuous beeps or blinking at the AC power adapter LED, there may be a power adapter fault. This may be due to an insufficient power supply.
Alternatively:
- Blinking battery power LED? Check your battery! It could be a fault caused by the AC adapter charging the battery, but not enough to power the notebook yet.
- Are caps or Num lock blinking once? CPU fault! Your CPU may not be functioning properly.
- Two blinks or beeps at the Caps or Num lock? BIOS fault! This could be due to BIOS corruption.
- Three blinks or beeps at the Caps or Num lock? Memory fault! It may happen when a memory module is not working properly.
- Four blinks or beeps at the same Caps or Num lock? Graphics fault! This may be caused by a malfunctioning graphic controller.
- Five blinks at the Caps or Num lock? System board fault! It may happen when the general system board fails.
- Six blinks or beeps at the Caps or Num lock? BIOS fault due to authentication failure!
- AC power adapter LED continuously beeping or blinking? Faulty power adapter! Check if you have enough power supply.
