Noise coming from AC adapter

My sony vaio has been through three different ac adapters. All three adapters made a weird insect like chirping noise everytime they were plugged in and eventually all three stopped working. how can i fix this? is the laptop shorting the ac adapters somehow?

    My ac adapter plug has a short, the prong that plugs into the computer. Sometimes it works, sometimes it chirps. Anyway, I have an adapter from a different computer but the prong is the wrong size. Can I get an adapter that I do not have to install? I want to plug the prong onto my old adapter, then plug it into an adapter that will fit my laptop.

There is a possibility that the power managment sestem in the computer has malfunctioned and is back feeding and burning up the supplies. You will need to take this in for a professional diagnostic to find out if you have a back feed problem. A back feed problem is rare, but not unheard of.

Battery/Ac adapter issues for Sony VAIO Model


So I gather the laptop does not run when the battery is in and the AC adapter is not connected? Laptop batteries tend to ware down over time and will need to be replaced as they end up not being able to hold any charge. Look online for a new replacement of the battery under the model number of your laptop

E6500 making a beeping noise


Does beeping noise happened before turning on laptop? If yes unplug the laptop from the AC Adapter. Just leave AC Adapter ON and connected to the power outlet. Check if AC Adapter is the one making beeping noise. Note: This is an issue with dell AC Adapter laptops
If no beeping noise in AC Adapter then proceed checking it from the laptop. Does beeping noise happened immediately when laptop is turned on? If yes then it might be laptop's hard drive creating the sound. Try to check the BIOS in your laptop under the category performance if the HDD Acoustic is ON either in Normal or Performance. Note: When laptop is in performance the hard drive makes noise due to its speed, this is normal if BIOS HDD Acoustic mode is ON to performance.
If the noise only happens when sometime while working on the laptop, this might be cause by the laptop fan. This also happens after turning on the laptop fan my have dirt and dust, please do check.
If fan was cleaned, HDD performance was checked and AC adapter was checked then, carefully sense if noise is coming from the internal speakers.
Download the latest BIOS update for your laptop then flash the BIOS. Make sure battery and AC adapter are connected when doing these.

Dead Sony Laptop


If power supply is supplying correct voltage, then you do not need power supply PCB.

Try starting the laptop with AC adapter and no battery, if battery is shorting out you may get same problem.

Test the soldering joint on the AC socket and laptop motherboard, if there is a bad soldering on laprop ac adapter socket, you get same symptoms.

If it is none of the above, and the adapter is fine, then it is usually a faulty motherboard.

Laptop battery and AC adapter


Replace the power supply first, chirping is not good, and if the supply has a low output it could be putting out just enough to run the machine and not enough to charge the battery. Starving the machine for power can damage the machine or the battery, so, you may still need a battery, but you won't know until you replace the supply. If you do need a battery, aftermarket or generic batteries are fine. I've used them and had no problems. Many times you'll find that the aftermarket batteries are made by the same company that the laptop manufacturer uses, they just don't have the label, it's this way with damn near all the laptop manufacturers.

Sony Vaio ac adapter submerged


If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.

If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.

Thanks
