Standard issue cleaning procedure seems to have gone wrong; I'll express what I did, what the problem is, and all investigations after the discovery of the problem: [ What was done ] :: The keyboard was set in a baking pan of isoprophyl alcohol for about 15 mins. with occasional swishing and then dried overnight in order to clean the board out as per regular maintenance. [ The Problem ] :: The "Left" key continuously fires off preventing any other key entry from being registered by the board. [ Attempted Fixes ] 1. The general uninstall/reinstall drivers and devices. 2. Alleviation of pressure on the left key by removing all top layers and plugging the keyboard back into the ZIF connector in concern that it was a simple membrane issue. 3. A full cleaning of the entire keyboard, removing all keys, holders, and the button layers followed by another day's drying. The thing is spotless and there is nothing to press on the membrane. 4. Virus scan with Avast / Avg, nothing came up. I'm sure I couldn't have covered everything. I know it's the left key is being depressed because I used a computer program called KeyBoard Test, gotten from their official website, and while I'm concerned it's a short I don't know how to test for that. Suggestions more than welcome! Specs: Gateway FX 6860, laptop part number: 90.4V607.N01
