Hello,


Usually a repeated beep sound indicates a problem with memory modules.

First use the following steps:

1 Disconnect battery and adapter (if connected)

2 If there are any devices connected to any USB ports, disconnect the same.

3 Wait for 2 minutes.

4 Press and hold down the power button for 30 seconds and then release power button

5 Connect adapter (do not connect the battery yet) and try to start by pressing the power button.


If you still get the beep sound, the next step will be to check memory modules

1 Turn off the system

2 Disconnect adapter and battery

3 Open the memory access cover at the back of the system

4 Take out the memory module(s).

Be very carefull. There are two ejector clips in both sides of the memory slot. Release the ejector clips by gently pulling them out of the sides of the module.
Gently pulling both clips at the same time will release the memory module.


The following video will provide more details:

(it is for different make/ model number, but the principles will be same)

5 Reinstall memory module(s)

If you have two memory modules installed, then try to test with a single module at a time



Let me know the results so that I can follow up further


Thanks

The tests you performed so far points to a motherboard problem.

Try the above listed steps again.

First reset the system (disconnect battery and adapter, press and hold the power button for 30 seconds and then release power button)

Then reseat memory modules and also test with a single module at a time


Sometimes this problem can also occur due to faulty memory modules but it is unlikely that two modules will be faulty at the same time.

You can also try to disconnect all additional hardware like Hard drive, CD/DVD drive from the system and then try to turn it on (with memory modules installed).

If it remains same, then the problem is due to motherboard
