Resposta para "Why is explanation mark on Wifi symbol"This happened to me yesterday on one tablet running Android 6.0 without issue for the prior 2 months on the same network, and my other 4.4.4 devices say nothing is wrong with the network, router or Wifi configuration. On examining the Xfinity router, it appears Xfinity pushed a new configuration to the router over the past days, as it has new software and the error appears on all Xfinity powered networks on the problem tablet. The tablet remains surfing without restrictions on Internet despite saying "Connected, No Internet". Its annoying as much as the "!" suggests something is wrong, but the bigger annoyance is Wifi has to re-selected every time the Tablet is turned on again, it can't connect automatically. I think this both a bug and a legitimate warning of an issue because after I fixed mine, I removed the fix, and the "!" remains OFF. For example, it works correctly on captive portal wifi such as in McDonalds or Starbucks. https://en.wikipedia.org/wiki/Captive_po... I think the "!" appears with too...
Resposta para "Why does water leak at the base of my coffee maker?"One thing not in the guide is steam condensation. You'll see small puffs of steam coming from the bottom. If enough deposits form around the aluminum tube connected to the rubber hoses, or the hose is old and brittle, it won't seal well so steam leaks out were the metal meets the rubber tube held by the spring clip, this condenses on the bottom as drips and drabs, rather than a bigger leak caused by a hole in the hose. Doing the vinegar clean on coffee maker while it is new will reduce the build up and prolong the life but it will happen anyway just at a later date or when the hoses give way. So if you intend to look for leaks, have a spare hose ready as even if it isn't leaking, just removing it could tear a worn, old, but still good hose.

Resposta para "What are your tips/tricks for removing or extracting stripped screws?"A method I use that works universally is a variable speed reversible powered drill and a steel drill bit. You can get screw extractor bits too, but in a pinch, even wood drill bits work. Just power the stripped screw with a bit in reverse; it eventually cuts enough grooves to pull it out, if it slips too much just work it out enough to use long nose pliers. For some really bad screws, it can help to first drill forward into the screw to cut a few grooves, thereafter reverse the drill. Cutting a long groove with Dremel's thinnest emery cutting disc creates a simple slotted screw head, but you can supplement it with the drill method to get enough clearance to keep from cutting the surface of your devices chassis. The above method may work on a Dremel tool, but drills always work, they have low speed, but a lot of torque.
