My charger suddenly disconnecting and reconnecting (Acer Predator 500 PT516-51s)

Something strange happened with my laptop Acer Predator 500 PT516-51s. Suddenly it disconnected for 1 second and connected to charging 2 times within a minute. I immediately thought that it was a connector, a plug or a power supply. I turned off and turned on the charging and there were no more disconnects and connections. I tried to shake the plug in the connector a little and bend the wire a little (within reason). Checked the plug, it's ok. My battery is perfect. I do not understand what happened. Just in case, I reset the battery by long pressing the power button, then calibrated the battery 2 times. I really do not understand what could provoke this behavior, the electricity did not turn off and my sockets definitely work. This happened again 1 time in a second after a week, I noticed that after turning on the turbo fans mode. I turned on the turbo fans mode again, but this did not happen again. But I'm not sure that this is due to the turbo fans mode. Someone faced similar?

Could also be a poor connection of the pin (barrel of the power plug) or (minor) fluctuations in city power, like where I live, causing this behavior. If it gets worse buy an additional power adapter with exactly the same Watt and DC Voltage out and most importantly the pin (OD+ID) and color code of the original power adapter. It always pays to have a spare adapter ($30).

Normal when under heavy load when the battery must help the charger meet the power demand. At those times, the battery is draining and not charging. When the load reduces, the battery starts charging again. If under continuous heavy load, battery charge level can drop below about 50% even though plugged in. When that happens, charging the battery takes precedent over the app or gaming load and throttling will start to happen. Then it's time to stop the app or game and let the battery charge back to 100% before resuming the heavy app or game load.

This happens if I pull out, then plug in the port. Then, for example, I want to move the laptop and twist the charger in the charging port a little. I don't know exactly when this happens, and it's only happened a few times. After that, everything is fine if I twist it again. The laptop is basically always connected and I do not twist the plug.

If it happens again, try to follow the basic steps given below.

I am really sorry for the inconvenience.. Let us do the basic steps first..

Doing the power drain and bios defaults will really help. Kindly follow the steps given below:

Turn off the laptop. Disconnect or unplug the charger cable, devices or any other cables connected to your laptop. Close your laptop. Turn it upside down. On the bottom of the laptop, you can find a pin hole. It is a tiny hole. You can a find a battery symbol indicator next to the hole. It is like a + and – sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer. Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop.

If you don’t find a pin hole on the back of laptop then you might be using removable battery. There is no need to unscrew anything to remove the battery. Turn off the laptop. Disconnect or unplug the charger cable, devices and any other cables connected to your laptop. Close your laptop. Turn it upside down. On the bottom of the laptop, please look at the top or bottom depending on the way you look at it. You can find a long door. It is a battery removable door. Just below that you can find a latch. If you move the latch you can remove the battery door. Once the battery is removed, flip the laptop. Open the top cover, press and hold the power button for 1 minute. Connect the battery back on the back of computer. Connect the charger cable back and then turn on the computer.

If you don’t see a reset pin hole on the back of laptop or if you are not able to remove the battery (if it is inbuilt) then please unplug all the cables and devices out of laptop. Hold the power button for 1 minute. After releasing the button you should wait a while before plugging in power. Just because the button has been pressed doesn’t bleed off all the residual electricity on the motherboard. Wait 15-30 minutes before plugging in power. Then once power is connected wait for a full battery indication before turning the system on. That allows the battery to fully reset it’s internal statistics.

Connect all the cables back and restart the computer.

While turning on the computer, tap f2. It will go to bios. Press f9 once. It will show load bios defaults with a yes or no popup. Press enter. Popup screen will disappear. Press f10 once. It will show save changes popup with yes or no. Press enter. Computer will restart and it will load into windows.

It might also be the issue with battery, charger or power outlet. Try to use the charger in a different room on a different power outlet. Try to bypass the surge protector and connect it directly to power outlet. Try to use an alternative charger if possible. Try to turn on the computer without the charger and check it ( as long as the battery is not drained out )

Try windows x
go to device manager
expand Battery
right click on all the items below battery – uninstall
Restart the computer

It should work fine..

I did everything you wrote, except for a new charger, it did not help. Charging disconnected after a short twist. It happens somehow by chance, now everything is fine. I will keep an eye on this and will most likely buy a new charger soon.

I understand you say "now everything is fine. I will keep an eye on this and will most likely buy a new charger soon."

I am glad it is working fine. You are Welcome!

»>Charging disconnected after a short twist. It happens somehow by chance, now everything is fine.

Stop trying to twist the plug. You might damage it. As mentioned earlier, the intermittent charging is normal when under load when the battery must help the charger meet the power demand. At those times, the battery is draining and not charging. When the load reduces, the battery starts charging again. If under continuous heavy load, battery charge level can drop below about 50% even though plugged in. When that happens, charging the battery takes precedent over the app or gaming load and throttling will start to happen.

Sometimes I have to do this because the charging port is very inconvenient. I've had laptops where the port was in the corner instead of in the middle. When there were sudden outages, I had to move it a little more to understand what the problem was. It happened all of a sudden and not even under load. I did everything that was written above, except for changing the charger. But the shutdowns repeated a couple of times, now they have stopped, and I no longer touch the port.
