Did I mess up my computer?

[jrodefeld]

Hello,

I didn't know where to put this. Just an hour ago I did something very stupid. I'm not sure what damage I might have caused.

I have a mechanical keyboard (Filco Majestouch 2) that is causing some problems. I have been trying to change the switch on a couple of keys and ever since removing some of the switches on the arrow keys, the keys won't register even though I seem to have installed everything okay.

So I thought "why don't I solder the connection a little to make sure contact is being registered". So I went to apply just a drop of solder to a contact point.

The problem is that I didn't realize that the keyboard was actually plugged into my computer when I tried to do that. So my computer basically turned off and tried to restart but the monitor won't turn on when it tries to boot.

To be clear I just touched a drop of solder to the key switch. I unplugged everything immediately after.

What could I have done by doing this? The soldering gun/solder must have sent some sort of voltage back to the usb port on my computer.

When I try to turn on my computer now everything lights up, the fans start, all the lights on the motherboard light up like their supposed to. But I hear no beep and the monitor never turns on.

My mouse lights up and it is plugged into the usb port on the motherboard.


What do you think happened? How do I troubleshoot this?

Start by clearing your bios (remove the mobo battery for a couple minutes with the power cord unplugged).  Try restarting after that.

There might be some form of surge protection (an old Asus laptop of mine had it, my father plugged something into the USB port and it sent a large amount of power into the mobo. Everything survived and the laptop still works!). If it does (which it should considering the laptop I am talking about is from 2009-2010), clearing the BIOS is a good bet. Otherwise contact the manufacturer, this sort of thing isn't as unusual as you might expect it to be. If you have a service centre near by, should be a 5 minute fix, if not, then you're in for a bad time.

 you must've bridged something,,   like 5v with data..

because otherwise the solder would've done anything..

Definitely sounds like surge protection, as jersern said try and de power for a while and then try again.
