What do beeping sounds mean when my laptop is turned on?

Last Update date : Sep 30. 2020

Refer the following pattern of beep sounds aimed at different scenarios:

 

One beep:

One beep from a Phoenix based BIOS is actually an all systems clear notification. It’s an indication that the Power On Self Test is complete. There is no troubleshooting necessary. 

 

One long beep, two short beeps:

One long beep followed by two short beeps indicates that there has been a checksum error. This means that there is some kind of motherboard issue. Replacing the motherboard should fix this problem. 

 

One-two-two-three beep code pattern:

A 1-2-2-3 beep code pattern means that there has been a BIOS ROM checksum error. Literally this would indicate an issue with the BIOS chip on the motherboard. Replacing the motherboard should fix this problem. 

 

One-three-one-one beep code pattern:

A 1-3-1-1 beep code pattern on a Phoenix BIOS system means that there has been an issue while testing the DRAM refresh. This could be a problem with the system memory an expansion card or the motherboard. 

 

One-three-one-three beep code pattern:

A 1-3-1-3 beep code pattern means that the 8742 keyboard controller test has failed. This usually means that there is a problem with the currently connected keyboard but it could also indicate a motherboard issue. 

 

One-three-four-one beep code pattern:

A 1-3-4-1 beep code pattern on a Phoenix BIOS system means that there is some kind of issue with the RAM. Replacing the system memory usually fixes this problem. 

 

One-three-four-three beep code pattern:

A 1-3-4-3 beep code pattern indicates some kind of issue with the memory. Replacing the RAM is the usual recommendation for solving this problem. 

 

One-four-one-one beep code pattern:

A 1-4-1-1 beep code pattern on a Phoenix BIOS system means that there is an issue with the system memory. Replacing the RAM usually fixes this problem. 

 

Two-one-two-three beep code pattern:

A 2-1-2-3 beep code pattern means that there has been a BIOS ROM error, meaning an issue with the BIOS chip on the motherboard. This Phoenix BIOS issue is usually corrected by replacing the motherboard. 

 

Two-two-three-one beep code pattern: 

A 2-2-3-1 beep code pattern on a Phoenix BIOS system means that there has been an issue while testing hardware related to IRQs. This could be a hardware or misconfiguration problem with an expansion card or some kind of motherboard failure.
