Acer Aspire 5520 failed to boot

[VictoriouZ]

I am having the Acer Aspire 5520 and facing some problem with that. Actually whenever I try to start that then it starts the power for about 3 to 4 seconds and after that, it again turns off. I tried to turn that on many of the times but all the times it shows me the same thing. Now I am stuck on this point and wondering that how it can be resolved? If someone of you can help me solve this then please post your suggestion over here. Thank you.

This is seems to be problem with the battery that might be not able to hold the power. So you should check for this condition and if require then just go for the new battery. I am saying this to you because it is more likely seem to be problem because of the battery and changing the battery will surely resolve the issue. So try this and let me know that if this solves the problem or not.

This looks like problem with the main board in that but I am not very sure about this. So checking for the battery problem first will be good for you. It will be helpful for us if you can provide some more information about this. Have you added any new hardware in your computer recently? I am asking this because that might be culprit for this. Or do you get some blue screen when it is shutting down?

This is seems to be problem because of some of the virus in your computer. So if you are able to start that then you can try to boot that in safe mode and see if that is getting booted or not. If that booted without any problem then you will have to scan your computer with the antivirus and clean the system. Once done with that then again try to restart it in normal mode and see if it is getting started or not.

A system restore can help you solve the issue. So if you can start the computer on safe mode then just do the system restore and this problem will be resolve. In the process of the system restore, when it asks you for the date on which you want to restore the system then you should select the last date when it was working well and that will cure the problem for you. So do this and let us know if this can solve the problem for you.

I'm struggling a bit the same with the Acer Aspire 5680. I have a somewhat similar problem with my Acer Aspire 5680. I turned it off after leaving my office and will not start at home. Showing some signs of power to light the power button, the flashing light on the hard disk and fan running for 5 seconds (stops and resumes after a minute), but nothing more. The screen is frozen from the beginning. Any help would be greatly appreciated.
