Hello,
I have Acer Nitro 5 AN515-51-77VW, using it for 4 years straight now. Lately I have done a little maintenance, which I always do (checking coolant paste, cleaning fans, etc), but this time after tightening all the screws, screen remains black, and I can't even get to the bios.
Is anything I should consider? Or I did something wrong?
Please help.

    You say "after tightening all the screws, screen remains black, and I can't even get to the bios.
    Is anything I should consider? Or I did something wrong?"


    Sometimes if the cables are not connected properly, if there is any loose connection we will not be able to turn on the computer.   Kindly try to check whether they are connected properly.    If not, try to reseat it again and then turn on the computer.  


    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 )

    Hello guys, 
    Really appreciate your helpful comments but resetting the battery for 30 secs didn't work (laptop has inbuilt battery).
    what's happening is, when I switch ON the laptop, the keypad lights up and I hear fan sound just after, screen all black. And then fan stops moving but after 2-3 seconds fan starts again with a tremendously high speed and it stays that way for atleast 3 mins and then shuts down.

    There are no wires loose inside (checked it 3 times already). 
    Tapped F2 key several times just after switching ON, no response at all.

  • Have you added any new hardware recently? Does your model have this button?

    Nitro5Rigger seeing that you have done all the standard consumer things to re vitalise and try to make your laptop work, IMO the fault is either with your LCD screens backlight or an internal Mosat, a resistor or a capacitor chip that are all an internal circuitry issue which has probably shorted or burnet out due to something that you have done while opening your laptop and/or statically shorted. All these sorts of problems needs an experienced tech to diagnose and fix as you can't do anything magical to make it work.

    Then check if the computer turns on.

    Yes, thank you, edp cable was the problem.

    BUT now, on powering ON(AC adapter connected), laptop starts up and shuts down again just in 1 sec, then starting up again, and shutting down automatically. It keeps happening until adapter is unplugged.
    And it's not powering ON on battery.
    Yes I have resetted the battery 3-4 times, still having the above issue.

    Perhaps when you took the laptop apart, this button was not pressed properly.
