Memory error
if the laptop is running and even boots up and the beeps continue it is the CPU (Overheat, not seated, cache memory error)

THe most common beeps that you will encounter 95% of the time in repairing PC's are:

1 beep - computer ok
continous beeps / long beeps - memory error
continous short beeps - bios boot block/corrupted bios
1 long beep followed by 3 short beeps - video card error


or this might help

you can check out this list



AMI BIOS

1 short - Computer ok
2 short - RAM failure
3 short - Parity RAM failure
4 short - System timer failure
5 short - Motherboard failure
6 short - Keyboard controller error
7 short - CPU failure
8 short - Video RAM failure
9 short - ROM BIOS error
10 short - CMOS read/write error
11 short - Cache RAM error
1 short, 3 long - Memory failure
1 short, 8 long - Video adapter failure

Check board/chipset makers website for more infomation.

AWARD BIOS

1 long - Memory error
1 long, 2 short - Video error
1 long, 3 short - Video failure
Continuous beeps - Memory or video failure

note that AWARD relies on motherboard manufacturers to develop their own beep codes - the above are only their own internal codes. You will need to refer to your own manual for an explanation of precise codes.


Standard IBM beep codes.

No beep - Power supply or motherboard failure

My computer beeps continuously every time i have it plugged in


Try this suggestion. Turn off your laptop, remove the cables and battery on the pc. Press and hold the power button for 8 secs. Then reinsert the cables and battery on the laptop and then turn on the pc. If it still continues to beep with no interruption, it is a problem on the motherboard. I suggest to call Acer and have your computer repaired immediately unless if you know how to reseat the motherboard by tearing down the laptop..

Laptop IBM ThinkPad. Black screen. Short beeps: 1+3+3+1


Hello,

You can try the following steps:

1. Unplug the power from the laptop and remove the battery then press the power button of the laptop for 15 seconds

2. Put the battery back in, turn on the laptop without plugging the power to the laptop (If this didn't resolve the issue)

3. Remove the battery and press the power button of the laptop for 15 seconds, after that, plug the power cord and turn on the laptop (if this didn't resolve the issue)

4. Remove the power cord and press the power button of the laptop for 15 seconds, disconnect the Hard drive and turn on the laptop (If this didn't resolve the issue) reconnec the hard drive

5. Remove the Optical Drive and turn on the laptop (If this didn't resolve the issue) reconnect the optical drive

6. Remove the memory chip, if you have 2 memory chips installed in the 2 memory slots (remove both of them) now test each one of the memory to each slots turning on the laptop. (If this didn't resolve the issue) Put the memory chip back in. (Clean the slots if there are large amounts of dust)

7. Reseat the CPU and try to make sure that it's installed properly. Turn on the laptop and test if it's gonna work (If this didn't resolve the issue)

8. Reseat the power cords coming from the power supply of the laptop and test the laptop. (If this didn't resolve the issue)

9. Disconnect everything and just leave the CPU installed and turn on the laptop.

10. If all else fails, there's a big possibility that the problem may be with the power supply or the motherboard of the laptop.

Problem for HP HP Pavilion dv2000 15.4" Notebook Laptop PC The power is OK but I get 1 long beep and 2 short beeps when switching on, the screen remains blank and no activity on the laptop


Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes Pc

More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.

Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it
Hope this gives you the information you need

System not booting


Try power cycling the laptop by taking the battery out and pressing the power button 10 times. On the 10th time, hold it down for 10 seconds. Put the battery back in and attempt to boot the laptop.

If that doesn't work, listen for a cooling fan when you attempt to boot the laptop. If you don't hear the fan, it's likely that the motherboard is malfunctioning somewhere.

Do you hear any beep codes when you try to turn it on? Here is a list of beep codes for reference:

No Beeps: Short, No power, Bad CPU/MB, Loose Peripherals
One Beep: Everything is normal and Computer POSTed fine
Two Beeps: POST/CMOS Error
One Long Beep, One Short Beep: Motherboard Problem
One Long Beep, Two Short Beeps: Video Problem
One Long Beep, Three Short Beeps: Video Problem
Three Long Beeps: Keyboard Error
Repeated Long Beeps: Memory Error
Continuous Hi-Lo Beeps: CPU Overheating
Hope this helps! Good luck!
