chip on the motherboard (CMOS). It controls systems devices and test memory. It allows you to configure specific parameters about the hardware in your computer such as time, date, disk drive parameters and other device settings. Beeps are emitted acer bios beep codes from a computer during the boot process when some problem is encountered and can be used to acer computer beep codes troubleshoot a dead computer. They indicate problems such as bad memory, bad keyboard or bad motherboard. Usually if you hear beeps there is something real laptop beep codes acer wrong and you should immediately turn off the computer and perform some troubleshooting. POST Beeping Error General Codes Bad Motherboard - 1 long and 1 short beep Disk drive related problem / Video card problem - 1 short beep then nothing

happens Bad video card - 1 long and 2 short beeps Bad power supply - 1) continuous beeps, 2) non-stop short beeps Bad memory - 3 short beeps These codes DO vary from one manufacturer to another. Almost all computers list the appropriate codes in the User's manual under technical information or the troubleshooting section, so be sure to check the manual and verify what the codes mean. If no beeps are heard and no display is on the screen, it's most likely the acer motherboard beep codes power supply. Check for Keyboard lights or for hard drive/floppy drive lights. If lights come on then power supply is good. Next, inspect the motherboard for loose components. A loose or missing CPU, BIOS chip, Crystal Oscillator, or Chipset chip will cause the motherboard not to function. If there are lights, then it could be one of the I/O cards. Try removing each card one at a time and restarting the computer.

Beep codes are used when an error occurs before the system beep error codes video has been initialized. Beep codes will be generated by the system board speaker, commonly referred to as the PC speaker. AMIBIOS displays the checkpoints in the bottom right corner of the screen during POST. This display method is limited, since it only displays checkpoints that occur after the video card has been activated. Not all computers using AMIBIOS enable this feature. In most cases, a checkpoint card is the best tool for viewing AMIBIOS checkpoints. Beep Symptom One short beep Continuous one long beep One long beep and two short beeps then repeat. One long beep then two short beep Two short beeps Chapter 4 Cause and Description System is ready. System is OK. Memory not installed or memory error. VGA not installed or VGA error. Graphics card error/not installed, graphics card memory error or graphics card BIOS checksum error. BIOS damaged. BIOS is damaged, BIOS POST jumps to Boot Block to execute the default procedures.
