I purchased a generic 45W apple laptop charger on the internet after the old one (original one that is 45W)was broken..and I used it for a day without problem. The 2nd day when I was using the laptop with the charger plugged in, the monitor screen started to freeze and eventually the monitor died. Then I noticed the charger I received was 65W, instead of 45W. The output was supposed to be less than 1.875 A but the 65W one has 2.65 A. The place sold me the charger replied to me that a 65W is actually better than 45W for power transfer. Could this have killed my monitor or is this just an unlucky coincidence?

Thanks,
Summer
 
I wouldn't think that it would be the power brick that did it unless that one wasn't really meant to be used with that computer. I know dell typically allows you to purchase a beefier power brick if you want, i'd assume so that your battery will charge faster while you're using the computer. I'm guessing it may have been a power brick that wasn't actually meant for the computer and it messed it up because that would be a really odd coincidence if you weren't having any problems before you went to the new brick.
 
As far as I understand Electrical Engineering (which is not very much, let me tell you...) under powering a device is extremely bad, but giving it too much should really hurt it all that much, if at all. The only part that I would be concerned about it the Amperage, the Watts and Voltage won't really matter at all, but the Amperage might be related. I'd see if there's anyone else with a better understanding of how electricity works.
 
we had somebody at work that used their docking station ps for their laptop and it fried the mobo
