Red light inside won't turn on and red Leds on and low fan in My nitro 7

My nitro 7 has red leds turn on inside the computer under the cooling fans. It sounds like the fans themselves turn on but run very lightly and the computer screen is black. When it turn on it makes a sound and seems to shut off and try again and then it just stays on with nothing on screen, the red leds on and low fan.

I had just opened it to clean the dust off the inside, my duster can shot out a few drops of liquid but I hope those just evaporated away. When I booted it up after cleaning it turned on fine but I waked away for a moment and when I came back I found it off and doing what I described above.

Would love some help to figure out whats wrong here.

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..

What is the exact Nitro 7 model laptop that you have, it should be something like 715-xx . Also, cleaning your fans and repasting the cpu/gpu is a very simple process and shouldn't do anything to your fans or laptop unless the fans had a previous problem with their bearings or their construction and by you opening and cleaning them, their problems have been magnified by either you cleaning them incorrectly or doing something to these fans?

My advice to you is this, open the laptop up again and inspect the fans again and see if there are no particles or any damage done by your duster. Also, what is this "my duster can shoot out a few drops of liquid " as you should only use a special fan cleaning brush and compressed air to get rid of dust or caked on grime from these fans and nothing with liquid or anything else, as anything else will damage these fans.

Below is the Acer SG thermal module removal for a Nitro 7 AN715-52 and the Fan 1 and 2 Module Removal (installation is the reversal of all this) and as you can see you need to remove and replace all components properly otherwise you could have done something wrong, and the fans might be blocked or interfered with and/or not installed properly or the fan(s) are faulty.

I have an AN715-51. Upon further inspection I noticed that the fans actually run for a second then turn off but if I leave it on they will kick in like normal so I don't believe they are damaged. The main thing is the red led under the fans which I am not sure what is supposed to indicate and that there is no image, screen doesn't not turn on keyboard does not appear to respond to actions. Battery charges as the charge light turns on. I found a sort of white/grey smudge over a connector on the top right(if the laptop is turned upside down with hinge on further side from you.) I tried to rub it off but not sure I got all of it.
