Double Beep from Laptop While Running


Sep 7, 2016
I have looked around for a solution or even mention of this problem and all articles mention cases different than what I experience. My Laptop has been making a two loud high pitch beeps spaced by 5-10 seconds from one another at roughly one hour intervals. These beeps can occur on a per hour basis but will not always do so. The event log doesn't show any failures or even mentions of this happening. Beeps will be projected through HDMI connections and become horrifically loud as they play through a 5.1 system. Only consistence is the fact that it is two slightly spaced beeps.
Try this..

Beeps at start up.

8 Beeps on startup means the LCD on system has failed (or is failing). 6 on startup would mean it is your GPU.

You might want to try running a LCD Test, as well as a Pre-boot System Assessment.

So now you are probably thinking "How to run these tests?" :)

First, turn off your laptop.

For the LCD Test...

1. Hold down the 'D' key and then turn on your laptop
2. Keep holding down 'D' and you should see color bars on your LCD.

Again, turn off the laptop...

For the Pre-boot System Assessment...

1. Hit the 'F12' key immediately after turning on your system.
2. From the options displayed, choose 'Diagnostics' .

This will tell you if there are any errors that you need to address/fix.

Other beep codes....

NOTE: Due to the fact that different manufacturers with this BIOS have different codes, the beep codes may vary.

Below are the AMI BIOS Beep codes that can occur.

1 short - DRAM refresh failure
2 short - Parity circuit failure
3 short - Base 64K RAM failure
4 short - System timer failure
5 short - Process failure
6 short - Keyboard controller Gate A20 error
7 short - Virtual mode exception error
8 short - Display memory Read/Write test failure
9 short - ROM BIOS checksum failure
10 short - CMOS shutdown Read/Write error
11 short - Cache Memory error
1 long, 3 short - Conventional/Extended memory failure
1 long, 8 short - Display/Retrace test failed
two-tone siren - Low CPU Fan speed, Voltage Level issue

Below are Award BIOS Beep codes that can occur.

1 long, 2 short - Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information.

1 long, 3 short - Video card not detected (reseat video card) or bad video card

Beeps repeating endlessly - RAM problem.

Repeated high frequency beeps while PC is running - Overheating processor (CPU).

Repeated beeps alternating high & low frequency - Issue with the processor (CPU), possibly damaged.

Dell beep codes

1 beep - BIOS ROM corruption or failure
2 beeps - Memory (RAM) not detected
3 beeps - Motherboard failure
4 beeps - Memory (RAM) failure
5 beeps - CMOS Battery failure
6 beeps - Video card failure
7 beeps - Bad processor (CPU)

Below are general IBM BIOS Beep codes that can occur. However, because of the wide variety of models shipping with this BIOS, the beep codes may vary.

No Beeps - No Power, Loose Card, or Short.
1 Short Beep - Normal POST, computer is ok.
2 Short Beep - POST error, review screen for error code.
Continuous Beep - No Power, Loose Card, or Short.
Repeating Short Beep - No Power, Loose Card, or Short.
1 Long and 1 Short Beep - Motherboard issue.
1 Long and 2 Short Beeps - Video (Mono/CGA Display Circuitry) issue.
1 Long and 3 Short Beeps. - Video (EGA) Display Circuitry.
3 Long Beeps - Keyboard or Keyboard card error.
1 Beep, Blank or Incorrect Display - Video Display Circuitry.
