Answers :

Hi,
1 long, 2 short beeps indicates a video error has occurred and the BIOS cannot initialize the video screen\015\012 to display any additional information.
This issue can be caused by any of the below situations.
\015\012 \015\012
    \015\012
  1. New hardware conflicting with old hardware.
  2. \015\012
  3. Bad or failing hardware device.
  4. \015\012
  5. Connections not connected or connected properly.
  6. \015\012
  7. Recent electrical storm that caused a surge that damaged computer.
  8. \015\012
  9. Other hardware issue.
Disconnect the RAM from the Motherboard and turn on the computer. If the computer has a different beep code or if your computer \015\012\011\011\011\011was not beeping and is now beeping turn off your computer and \015\012\011\011\011\011try the below suggestions. Making sure to turn off the computer each \015\012\011\011\011\011time you're adding and removing the memory and then turning the \015\012\011\011\011\011computer back on to see if the suggestion resolves the issue.

Re-insert the memory into the same slot.\015\012
    \015\012
  1. If you have more than one stick of memory remove all but \015\012\011\011\011\011\011one stick of memory, try rotating through each stick.
  2. \015\012
  3. Try one stick of memory in each slot.
\015\012\011\011\011If you're able to get the computer to boot with one or more \015\012\011\011\011\011of the sticks of memory it's likely you're dealing with some bad \015\012\011\011\011\011memory. Try to identify which stick of memory is bad and replace \015\012\011\011\011\011it.
\015\012\011\011\011If you're able to get memory to work in one slot but not \015\012\011\011\011\011another slot. You're motherboard is defective you can either \015\012\011\011\011\011workaround the issue by running the memory in a different slot \015\012\011\011\011\011or replace the motherboard.
The RAM is located under the laptop behind a hidden panel.


Good luck and let me know how you get on and if you need any more help or advice.
