There was problem in the display of my laptop. Some times the display would come and sometimes it wouldn't.The power would be there always ,there was no problem with it.Sometimes after trying two -three times the display would come and then it worked properly till the time I logged off. I took it to the Acer service centre CODEICON IT SOLUTIONS PRIVATE LIMITED S ,,G-6 Om Heera Panna, Oshiwara, Andheri (west),Mumbai 400053. on 26/12/2009 They said that it was NVIDIA problem ,job no. 116 and charged me Rs.3500/-on 29/12/2009 and returned my laptop. The display did work properly for a couple of days but again on 31/12/2009, the display did not come. I took it again to the same service centre, and they said they would fix it again,job no.137.
They gave it back on the 2/01/2010 but I had to give it back to them the very nextday as the display stopped showing.The power was still coming only the display was not showing.From 3/01/2010, they kept my laptop till 29/01/2010.and when they returned it they said that it was dead.During the one month that the laptop was with them they first said it was NVIDIA problem,then it was the processor, then it was fan and then they returned it dead saying it was motherboard that needed to be changed..they retuned the the Rs.3500/ by cheque that they had initially charged.but returned a dead laptop,where as I had given them a laptop that had power and only display problem.As per my knowledge the engineer had also gone for a holiday .
I brought this to the notice of Ms. Shubha Sharma,acer Support Centre,Mumbai and she sent my Laptop for rechecking at another service centre at Mahalakshmi,Mumbai,She said that the motherboard and fan needed to be changed.I spoke to her manager aswell but it didnot help either. what he offered was a 5% discount on the motherboard and free replacement fo the fan.
But my reasoning is that when I had given my Laptop to the service centre it was not dead and after a month the ygive it back to me in a dead condition. Who would be responsible for this and does it take a month to doagnise the problem. Was this information helpful? | 
I have an Acer 4520 but the problem is similar to yours .In your case the problem was intermittant in the
start but fortunately to your good luck it did not go dead in your hands. The root cause of the problem is
the Nvidia Graphic Card . There are two types of 4520 one with onboard Graphic and one with a slot where
a card like this http://www.ioffer.com/i/nvidia-graphics-card-geforce-88600m-gt-8600mgt-512m-mxm[...⇄ is attached. If you have a slot for the card then replace it with the one like this as it will work .
It is a known Nvidia Graphic Card weak die problem, if you do a google search you see that Nvidia openly
said it was a weak die cast problem.
I m reachable on [protected]@yahoo.com / [protected] as i too want to fix the same problem with my laptop.
