Wondering if any of you could provide some explanations on what may be causing my laptop to not even want to turn on. It happened after I had cleaned my screen with Windex (has ammonia in it). My charger works just fine since it keeps my other computer on without the battery cartridge attached to it.

Admittedly , there seems to be a crevice towards the bottom of the screen. Would really appreciate it if anyone here could provide some troubleshooting tips on where to look or which part may need to be replaced.
 
Did you spray the screen directly or spray it onto a cloth and then wipe the LCD? If you sprayed directly, it may have seeped into the LCD and damaged the inverter, which in turn damaged the motherboard.

thanks, that's the kind of the explanation that I was looking for. so are you saying that I might as well get a new computer or perhaps is there a way to recuperate it?
 
So I take it that's what you did. If the motherboard is fried, then yes, you'll just want to get a new laptop.
 
Take the battery and power plug out and hold down the power button for 45 seconds. Then replace the battery and power plug and try to start it again.

Thanks a lot for your advice on this. did this a couple of times along with opening up the laptop (the base as well as the screen) to dry the system and it eventually turned on. however, the screen is really dark/dim, could barely make out anything unless I shine a flashlight on the screen.

Read online about this and it seems that the lid closing/shut off mechanism might have been altered or something while disassembling the laptop. Any troubleshooting tips on this?

Advice would be much appreciated.

No its not the lid close sensor. Your back light seems to have burned out. You'll need to replace the LCD panel.
 
a few years ao my dad sprayed his dslr with windowlene and it went dark, he had to dry it out so that he could see the screen again, it was really dark

any way to check if this is really the case? i.e. tests. Would rather not spend 100s of dollars on a new screen and then find that another issue was at the root of the problem.

so he actually got it to work again? did he open up the entire laptop or perhaps just the screen itself?

You can pick up a replacement screen on eBay for $60. Just pull it out and stick the model number in eBay.

it's a led screen, not that it would make much of a difference. admittedly it was a pretty boneheaded move on my part.

No worries, everyone makes mistakes. Ideally you would use monitor wipes, but if you use any sort of a spray it should be sprayed to a towel and not directly on the monitor (but I'm sure you know that now ;) ).

I don't believe ammonia should be used on any electronic display, but I could be wrong.

You can be connected via the VGA display to see whether to open the laptop, so will be able to determine whether there are other problem.
 
Look at the end of the day, if you've stuffed the inverter or fluro, not seperate vga will show this. The only thing it will show is that the gpu is still outputting. At that stage you know the issue is downstream from the vga output (e.g. fluro or inverter).
 
I would just buy a new laptop provided I have the money. You could always keep your current laptop and buy a new screen and see what happens if you wanted.
