I have an Acer Aspire VX 15 (VX5-591G-78FB), that I've owned for over 5 years, so it's well past it's warranty.

today, I'm cleaning and repasting my motherboard but after putting it all back on, problem arise. first, it has blank screen and blinking LED and keyboard at the same time at 5 second interval and after that, it turns off. so I tried to removing the RAM like this thread :

but then, it creates another problem where it still has blank screen but keyboard and power LED stays on, and also after a minute, the fan turned to full speed but still, no acer logo.

I'm thinking of replacing the CMOS battery (CR2032, 3V == 220 mAh). but let me know if you guys had other solutions, as I don't have the money currently to send it to Acer repair center.

    Was the battery pack connector unplugged from the mainboard?

    Do a hard reset, by disconnect the main battery and the RTC/bios battery (a dead bios battery does not stop your laptop from booting, but you can check its voltage with a multimeter) after taking both batteries out, short both +/- pins at the mobo to do a complete reset.

    Btw, to do this reset you don't have to take these two batteries out, just unplug their plugs from the mobo and also take the ram out and clean its pins. Leave them unplugged for 5min and then reconnect everything, Also and if you didn't disconnect the main battery the first time and did all this work and repaste with the main battery connected, then you could have caused a short.

    Also look at the screen cable/plug, if its connected properly or not damaged, as that could also be a major cause of why you are not getting an image, so check that, or you could have caused a short somewhere (which is very unlikely but could be the reason?) and that is why you are getting these problems.

    I understand you say it has blank screen and blinking LED and keyboard at the same time at 5 second interval and after that, it turns off


    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 fn + f5, fn + f6 on keyboard to get the display back.. Hold the fn key and press f5 or press f6 on keyboard only once.


    Try windows x 

    go to device manager 

    expand Battery

    right click on all the items below battery – uninstall 

    Restart the computer 


    Try fn + f5, fn + f6 on keyboard to get the display back..

     

    It should work fine..

    sorry, apparently the problems were RAM. I've tried booting with other spare RAM from my friend and now it can boot up nicely. thanks for all the answers, guys!

    Thanks for reporting back. Try gently wiping the gold colored RAM module contacts with a soft cloth lightly moistened with rubbing alcohol to try to clean them.and make better contact with the mainboard RAM connector.
