Concept D 7 - CC715-71 Laptop went dead while using it...

Laptop:

Concept D 7 - CC715-71 / NXC5AAA001XXX, purchased 10/3/2020.

I was working on my laptop when it went completely dead. The red lights on the front are now out, even with the power supply still connected. The laptop will not turn back on.

I verified that the AC adapter is producing 20V DC, so I've ruled out the power supply.

Any ideas?

Where should I take the laptop for repairs?

Try to do the Battery Reset first, this laptop has a small pinhole at its base at #1

If the above doesn't work then do a hard reset by removing the four (4) side rubbers from the bottom, then remove thirteen (13) screws from the base cover, carefully pry up the base cover from the left side to release the latches then Grasp and slide the base cover to the right to remove it from the system and then disconnecting the main battery, RTC/bios (that is in the left corner) batteries and take the ram out also.

Leave them disconnected for about 5min and reconnect all, then, reboot laptop, as this should reset your laptops super IO startup chip and bios completely. If this does not work, then you as a user can't do anything more as your laptop has other issues with power in its primary circuitry stage and/or with its mosats, capacitors and fuses etc that needs to be analyzed and tested by an experienced technician from either Acer or a local in your area, to fix your laptop.

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..
