I really admire people like you that dig in and fix stuff like that.
I did manage to replace a broken micro USB jack on my tablet. Used the mini screw driver set I bought at Radio Shack come to think of it.
I had no idea a screw could be that tiny - had to stack up two pairs of reading glasses on my head just to see it.
When I had to replace the charging port on my kids brand new Dell laptop because it broke off the MB, the part cost me $7.50 and I bought an insanely cool rugged set of tools for fine work online at Amazon for about 15 bucks (they had about a dozen or more types to choose from)
Neither of which I would have been able to get at Radio Shack.
Their solution to this problem?
Stock up on Chinese garbage nobody wants to buy.
Anybody still invested in this company is a sucker,or complicit.
