Acer Aspire 7720 Laptop shows green light but will not start..

I have a Acer Aspire 7720 Laptop computer that was cutting out on 
me at times..Upon reading in a Computer forum it suggested how to
clean the dust from the fan that could be a over heating problem..I 
managed to follow their instructions...but now when I switch it on..
all I get is 2 green lights come on to suggest the power is on, but the
 machine does not actually operate or come on as such. I later 
learned sometimes static could have been a problem, but had no 
prior warning on the initial forum I took notice from. Generally Ive 
found laptop repairs in the UK ,if are possible to do via anything on the 
motherboard or small parts are between £60 to £100.
I can buy a new laptop at PC world for £170..I would think the Acer aspire
7720 is now an old machine and would be worth little...
Its a shame however as this particular machine has not been used that much.
I wonder if anyone could advise if they think it may be possible to repair for 
an average person..what the fault is likely to be &  or what one would expect to pay if they had someone look at it at a Computer repair shop if it is classed as likely to be a difficult task to repair for an untrained person..I have had a little repair experience some years ago. and think I could do some basic part changes and soldering...but more involved longer task may be beyond my abilities..
Thank you

Static is definitely one possibility.

Another possibility is that you unplugged a cable somewhere when you opened it up, maybe.  Even though the green light(s) are coming on, the rest of the motherboard may not be getting power if the cable is unplugged.

I'm probably wrong, but just trying to help.

  • Hi GeekU Freshman,

Apologies for delayed reply,


Not long after my initial posting..I had an unexpected family issue that I had to deal with.. 


I had another look at my Laptop to check if I could see any unplugged cables that you suggested...

I could not see anything unconnected....There was only one or two wires / connections in the area where I had 

worked on when I cleaned the dust out of the Fan...and all were ok...


I suspect that it may be a static problem...but I am unsure how the machine would have been damaged 

by it, if it was static that has caused my problem...I assume that it may have permanently damaged something 

on maybe the motherboard that will need to be replaced..that may be quite an expence..

It costs about £60 in the UK to have a Laptop checked out with a basic repair..maybe more dependent upon 

how bad it may be...


I may be able to buy another reasonable Laptop for just a bit more...that it may not be worth having it repaired.

Unless I can find say a student who may be at a College who can repair it cheaper or something like that...


Unless anyone else has any other suggestions.


Thank you..
