• Was someone trying to steal a garage door opener code? See details.?

    My neighbor has a scary experience today. When she came home, she drove down our street, which has a median, and noticed a car slowly backing out of a cul-de-sac in the wrong direction. She drove around the back of the building to access her garage, and the car sped up to catch up with her. It stopped outside her garage. When she started to back out... show more
    My neighbor has a scary experience today. When she came home, she drove down our street, which has a median, and noticed a car slowly backing out of a cul-de-sac in the wrong direction. She drove around the back of the building to access her garage, and the car sped up to catch up with her. It stopped outside her garage. When she started to back out to better straighten out her car, it sped away. I think someone in the car had some kind of scanner and was trying to catch her opener's code. Does that make sense? I don't know what else would explain the suspicious behavior. Is this sort of thing often done?

    And I get the dreaded "plugged in, not charging" message when I mouse over the battery icon in the task bar. I've researched it and tried all the suggestions. It does charge briefly when I go into the BIOS screen by pressing F2 at start up and do a "save and exit" (without actually changing anything). Then it will charge for a brief time, maybe a minute or so, then stop charging. I can tell if it's charging or not by the lights. A white light on the side of the laptop tells me the AC adaptor is plugged in, and an orange light next to it tells me when it's charging. The OS is Win 10 Home 64-bit. The laptop is an ASUS Q505U purchased last November. How can I get it to charge again? I can't tell what's wrong or how to fix it.

  • How confident are scientists that certain meteors are from Mars, or when they were formed?

    E.g., Wikipedia has "a meteorite found in 2011 in the Sahara desert, was determined to be from Mars and found to contain ten times the water of other Mars meteorites found on Earth.] The meteorite was determined to have formed 2.1 billion years ago during the Amazonian geologic period on Mars." That's pretty specific and pretty... show more

That's pretty specific and pretty fantastic. Too fantastic. it seems too far a stretch to be believable. Now, I'm not a science denier--far from it. But his just strains credibility. Comments would be appreciated. "These meteorites are thought to be from Mars because they have elemental and isotopic compositions that are similar to rocks and atmosphere gases analyzed by spacecraft on Mars." Do we really have enough detail to say these came from Mars. Again, it strains credibility. And couldn't the composition similarities be a coincidence?

  • In Excel 2016, how do I determine what style has been applied to a cell?

    A lot of cells have messed up number formatting but I can't tell which style was applied to them. I want to change that style so that cells throughout the worksheet have the correct format (but many cells have a different style/format applied and I want to retain those).

Maybe the cells aren't formatted by any style, but just have an ad hoc formatting change. In fact, that's likely. But I'd still like to know if there is a way to tell what style, if any, has been applied to a cell.

  • Where did my old email accounts go after installing a MS Exchange Server account?

All my prior accounts are gone. I had the impression that I'd have a change between switching between them, but I don't see any way to do this. So what happened when I installed the MS-ES account? I made the poor choice of installing this late on a Friday afternoon, and I think the company's IT person is gone for the week-end, so I'm SOL on the prior email accounts, it seems. I can access them by logging in via a browser, but I had a lot of saved emails no longer on the server. I have the .pst files, so I can recover them, I'm pretty sure. But I don't really understand what happened or how I should have done things. Probably using a dedicated PC was the way to go.

    Some of the SUV's I've seen don't seem very roomy back there. I like the vehicle style, but I'd want to have plenty of room for luggage for 4 adults.

  • How durable are today's 2-in-1 computers?

    I am replacing my physically broken down HP laptop. Maybe I'm hard on laptops, or maybe HP's don't hold up (the touch pads have always been crappy, IMHO). I'm wondering if a 2-in-1 would last under my "normal" use. Or would a traditional laptop be a better choice?

It's a shame, since it still functions well, but just won't hold up much longer (thanks for your product quality, HP). It has a Intel Core i7-4700MQ CPU, which is fairly high-end for laptop, from what I can tell. Is there some way I can salvage this and put it into another laptop? I'm trying to save money on my next laptop. I hate paying for a new Core i7 CPU when I have a perfectly good one. If there's a way, how difficult would it be to install? I've done some work inside this laptop, replacing the fan and the mouse pad, though I'm far from an expert technician. But I'm willing to try it myself if it's not an extremely difficult thing to do.
