Laptop Power problem
My Laptop is of “Toshiba Satellite L850-166” model and the port based on the left (probably v2.0) is connected with a 2.0 4 port hub. 3 ports are in function (connected with a keyboard, mouse and a numeric keybad), regardless, all of a sudden (constantly) the power comes and goes no matter how many ports I use and no matter how quick I use my keyboard and mouse.

1) What is the cause of this and what is the remedy?

 * Just to clarify, you mean the power to the devices connected to the hub goes out, but the laptop itself still has power, for example to the screen ? If so, then the hub sounds like the problem, with a loose connection between it and the laptop.  Check the cord to make sure it isn't loose, at either end (or just the one end, if it's permanently attached to the hub).  Also check that when you plug in any device directly to the laptop with that hub, that no power loss occurs.  If that's not the problem, then the loose connection is most likely internal to the hub, which isn't so bad, as hubs aren't that expensive to replace. StuRat (talk) 18:59, 11 December 2016 (UTC)


 * Are you perhaps using an unpowered hub? If the combined power need of your devices is around the limit of the laptop's USB port, that could cause this intermittent failure. Distributing your devices over more USB ports on the laptop would be one solution, using a powered hub instead would be another. Jahoe (talk) 13:53, 16 December 2016 (UTC)
 * Jahoe: Points noted. Since you stated, I believe it is the case. Though I wish to ask, "Do you think USB 3.0 hub port(s) would do the trick, without a power plug?" - My Laptop consists of 3 USB ports, I believe v2.0 on the left i.e. currently in use with the keyboard, numeric keypad and a mouse (all of which, I believe, is of v2.0 port). And, two v3.0's on the right-hand-side which is also in use. I'm buying 'two 16 port v3.0 hubs' for the right-hand-side, they might not come with a power plug as I was unsuccessful with my research. Will it be an issue regardless of what or the many (v2.0 and or as well as v3.0) ports I use on the two right-hand-side ports...? I hope you understand what I mean... 103.230.105.23 (talk) 20:31, 16 December 2016 (UTC)


 * A USB 2.0 port typically supplies only 500 milliamps so it might not be adequate to run three devices. USB 3.0 increases the current available to 900 milliamps, but this is unlikely to be sufficient for sixteen devices unless they each draw only a very small current.

Fullscreen in YouTube
YouTube videos that previously could play full screen in Windows Vista have since November displayed instead "Your browser doesn't support full screen". Neither Vista nor the browser have changed, fullscreen remains available on videos at other web sites and in other browsers so apparently YouTube's player deliberately targets Windows Internet Explorer 9 with this change. How is that done and can full screen ability be restored in this browser? — Preceding unsigned comment added by 2A02:FE0:C400:4:D13B:E20D:5FBB:EBFE (talk) 22:30, 11 December 2016 (UTC)


 * Perhaps MS wants to get you to upgrade your O/S, so has let YouTube know that the IE 9/Vista combo is no longer fully supported, while the other browser's companies have no desire to get you to upgrade your O/S, so continue to support Vista ? StuRat (talk) 23:22, 11 December 2016 (UTC)
 * More likely, Youtube changed something which broke compatibility with IE9. I doubt MS could or would leverage Youtube into advertising for OS upgrades. Tigraan Click here to contact me 10:32, 12 December 2016 (UTC)


 * I hate to be "that guy", but is there any reason for you to stick on IE9 insted of upgrading to IE11 or another browser (Firefox or Chrome)? And did you clean up cache, temporary files etc.? Tigraan Click here to contact me 10:32, 12 December 2016 (UTC)
 * Since IE9 is the last IE version available for Vista, the question becomes shall I be forced to abandon IE 9/Vista (both products of that philanthropic gentleman Mr. Gates) by Google's cynical insertion of crippleware in YouTube. — Preceding unsigned comment added by 2A02:FE0:C400:4:D13B:E20D:5FBB:EBFE (talk) 12:56, 12 December 2016 (UTC)
 * OK, I tried to avoid going full free-software-zealot, but that is a bit rich. If BenRG's comment below is to be believed, what you call "insertion of crippleware" I call "deprecation of old crappy standards". Flash is a huuuuge security hole whose demise is long overdue. Although HTML5 arguably has issues of its own, it still is much better. If a 100% Microsoft OS/browser combination cannot handle that, the fault rests squarely on Microsoft's shoulders: either they are not able to create a compatible solution (and considering they are part of the W3C who made HTML5, they can hardly claim they were taken by surprise), or they are not willing to do so, and should take full responsibility for that.

 * Internet Explorer does support HTML5, even IE9. I'm not sure whether the OP's full screen problems are a limitation of the browser or some hardware config problem. But consider that Windows Vista was RTM in late 2006 which was before Opera had even proposed HTML5 video, before a lot of the world had even heard of the iPhone, even longer before most people had even heard of Google Chrome, and around the time YouTube was was purchased by Google. Mainstream support of Vista ended over 5 years later in 2012. IE9 was released about a year earlier. This was about a year after one of Google's engineers suggested HTML5 wasn't yet suited for all environments, amongst other reasons because many browsers didn't support full screen properly including a mention of WebKit. Nil Einne (talk) 10:43, 13 December 2016 (UTC)
 * which is from the year Vista mainstream supported ended suggests Microsoft was a bit behind in adding full screen capabilities, although this is likely at least partially reflective of their general slow release cycle of browsers (which IIRC after the long lull during the IE6 days, wasn't that far off Firefox's release cycle before they went full Chrome mode). Perhaps more interestingly, Opera the original proposers of HTML5 also lacked full screen support at this time. (This doesn't mean Google's at fault for deciding to make HTML5 the default.) Nil Einne (talk) 10:54, 13 December 2016 (UTC)
 * I suspect this is related to Youtube's switch from Flash to HTML5 video. If this thread is to be believed, they switched IE9 over to HTML5 on November 29. You may be able to force Flash by using IE's compatibility mode, as suggested here, but that thread is from April and I don't know if it'll still work. You may also be able to do it by adding "&html5=0" to the URL, but that may also be disabled now.
 * If you switch to another browser, note that Firefox still supports Vista, but Chrome doesn't. -- BenRG (talk) 04:48, 13 December 2016 (UTC)

Get the recent Flash Player, Version 24.0.0.186 If You can, upgade IE9 to never Internet Explorer, or just use Firefox. Note, toggle to fullscreen of web browser with F11 key, fullscreen of YouTube is the button on the right bottom of the video. Check settings of browser, if disabling fullscreen is setting. Else, check drivers of graphic adapter. -- Hans Haase (有问题吗) 17:15, 14 December 2016 (UTC)
 * For IE and ActiveX: https://fpdownload.adobe.com/get/flashplayer/pdc/24.0.0.186/install_flash_player_ax.exe
 * For Firefox and without ActiveX: https://fpdownload.adobe.com/get/flashplayer/pdc/24.0.0.186/install_flash_player.exe
 * I don't understand "upgade IE9 to never Internet Explorer". F11 merely removes top and bottom menu bars and does not affect video player size. 2A02:FE0:C400:4:D13B:E20D:5FBB:EBFE (talk) 20:53, 15 December 2016 (UTC)
