A boot alarm is the series of beeps that can occur if your laptop is experiencing hardware failure during start up. Normally, your Acer laptop will only beep once during POST. POST is a part of BIOS and loads all the initial systems and hardware your Acer laptop needs to function. You can diagnose the error by listening to the number and frequency of beeps you hear.
1 Turn on your computer and listen to the number and pattern of beeps you hear. 2 Write down the sequence and number of beeps you hear during POST. 3 Open your Acer laptop's instruction manual and locate the section named "POST errors." Depending on which motherboard your computer has, you will be able to locate the error by the number of beeps you hear.
