Amber-Computer is running on battery and the battery has less than 5% charge. Off ● Power adapter is connected, and the battery is fully charged. ● Computer is running on battery, and the battery has more than 5% charge. ● Computer is in sleep state, hibernation, or turned off. The power and battery-status light blinks amber along with beep codes indicating failures. For example, the power and battery-status light blinks amber two times followed by a pause, and then blinks white three times followed by a pause. This 2,3 pattern continues until the computer is turned off indicating no memory or RAM is detected. The following table shows different power and battery-status light patterns and associated problems. Table 23.

—Computer is running on battery and the battery has less than 5% charge.
Off
●
Power adapter is connected, and the battery is fully charged.
●
Computer is running on battery, and the battery has more than 5% charge.
●
Computer is in sleep state, hibernation, or turned off.
The power and battery-status light blinks amber along with beep codes indicating failures.
For example, the power and battery-status light blinks amber two times followed by a pause, and then blinks white three times
followed by a pause. This 2,3 pattern continues until the computer is turned off indicating no memory or RAM is detected.
The following table shows different power and battery-status light patterns and associated problems.

Problem description
Recommended solutions
1,1
TPM detection failure
Replace the system board.
1,3
Short in hinge cable tripped OCP1
Check if the display cable (EDP) is seated
properly or pinched at the hinges. If problem
persists, replace either display cable (EDP) or
display assembly (LCD).
1,4
Short in hinge cable tripped OCP2
Check if the display cable (EDP) is seated
properly or pinched at the hinges. If problem
persists, replace either display cable (EDP) or
display assembly (LCD).
2,1
Processor failure
Run the Intel CPU diagnostics tools. If
problem persists, replace the system board.
2,2
System board: BIOS or ROM (Read-Only
Memory) failure
Flash latest BIOS version. If problem persists,
replace the system board.
2,3
No memory or RAM (Random-Access Memory)
detected
Confirm that the memory module is installed
properly. If problem persists, replace the
memory module.
2,4
Memory or RAM (Random-Access Memory)
failure
Reset and swap memory modules amongst
the slots. If problem persists, replace the
memory module.
2,5
Invalid memory installed
Reset and swap memory modules among the
slots. If problem persists, replace the memory
module.
2,6
System-board or chipset error
Flash latest BIOS version. If problem persists,
replace the system board.
2,7
LCD failure - SBIOS message
Replace display vable (EDP) if possible,
otherwise replace the display assembly
(LCD).
2,8
LCD failure - EC detection of power rail failure
Replace the system board.
3,1
Coin-cell battery failure
Reset the CMOS battery connection. If
problem persists, replace the RTC battery.
3,2
PCI, video card/chip failure
Replace the system board.
3,3
Recovery image not found
Flash latest BIOS version. If problem persists,
replace the system board.
3,4
Recovery image found but invalid
Flash latest BIOS version. If problem persists,
replace the system board.
3,5
