I recently bought a laptop off eBay that was claimed to work. The laptop did not come with a power supply or a battery which I have bought and will arrive on Tuesday, for now I have no idea if it works or not I'm just trusting what the seller said and after doing a full disassembly to look at the motherboard to find everything was fine except for the ram slots. I have already cleaned the ram's contacts with distilled vinegar but knowing me I probably damaged something so because I think I damaged the ram I need another way to clean the slots they go in as I am not willing to get vinegar on the motherboard and break that too. Now I have seen that alcohol works great so I ran down to the store and bought some and came home, to make sure that this will even work I googled it and always got that I have to use 90% or higher because of something to do with water content, the store only sells 70% which is what I got if someone can tell me if I can actually use this it will be appreciated, if it won't work thats ok with me because I only paid $2 and on the weekend i'll try and find 90% or higher.
Thank you for your help.
