The Cause of Problem:

The Power Buttons electrical circle sometimes just braked it by one of sensors and the result is the 2 beeps and Power Supply is in protected mode error.

The whole computer is turn off but the power button is turn on and this is the nub of the matter. Because if you want turn on the computer you can't because already turn on but just the Power button and you can't do anything.

The solution:
You need just change the Power Supply and don't do anything just the power cable put into the Power Supply after turn off computer.
Finaly change back the Power Supply.

My acer aspitre 5733Z makes a loud beeping noise on a black screen and won't stop until i shut it off? I tried disconnecting the battery but its not that?


First, try removing the battery and unplugging the laptop. While still unplugged and with the battery still out, press the power button for 30 seconds or so (this will release the static electricity inside). Then put the battery back in and start it up again. This is called a hard reset, and it will fix a number of problems.

Dell inspiron 530s won't boot up and gives me 4 beeps a pause, 4 beeps etc.


4 Beeps indicates a RAM memory failure. Disconnect power, press and hold the power button to release all power from the motherboard, then re-seat the Memory.

If error doesn't go away, try modules one at a time to find the bad one

It is beeping "Error" with 5 beeps


5 beep error means that the waste ink tank is full. You can reset the counter to make it print by doing the following: You have to be exact. If you make a mistake in any of it, just go back to the beginning and start it all over.

1.Unplug the power cord from the printer

2.Hold down BOTH the POWER and RESUME button at the same time and then plug the power cord back in. Keep holding down the buttons until the printer finishes its powering up noises.

3.After the printer is quiet, release the POWER and RESUME buttons. Then hold down the RESUME and CARTRIDGE buttons at the same time with one hand, and press the POWER button with the other. KEEP HOLDING DOWN the RESUME and CARTRIDGE buttons until you hear 2 beeps. They will come quickly together and one beep will be longer than the other. Listen carefully, as they are not very loud.

4. Once you hear the 2 beeps, release both buttons.

5. After both buttons have been released, then press the CARTRIDGE button 15 times. You will hear a beep each time it's pressed.

6. After you finish pressing the cartridge button 15 times, then press the RESUME button one time. The printer will beep and shut off.

7. Turn the printer back on by pressing the POWER button. The printer will work fine now. The waste ink will have been reset to 50% full.

You should clean or replace the absorber pad at some point but most of the time you can get away with resetting the ink counter a few times before you need to clean or replace the pad.


1: Unplug Power Cord
2: Hold POWER and RESUME buttons
3: Plug in Power Cord
4: Release buttons after the printers starts up
5: Hold CARTRIDGE and RESUME
6: Press POWER
7: Release all buttons after the beeps
8: Press CARTRIDGE 16 times
9: Press RESUME
10: Unplug the Power cord
