I called the power company to ask wtf happened and they claimed they saw no evidence of a power surge or spike on their end at the time frame I gave, but that because of the heat lots of people were using A/C and that may have caused a very small "undetectable" spike. Frankly, it felt like the service rep was trying to give me as little info as possible, perhaps thinking I might take them to small claims court or someshit (which I'd have done if anything actually expensive had been fried).</p><p>I had no interest in that and just wanted to find out what happened so I could prevent it from repeating. After no help from the company I spoke to some neighbors and nobody else had experienced a power flicker at the time I did. Finally, I checked over my power strips and found that one was not surge protected at all and another for a laughably small protection. So I upgraded all of my power strips to high Joule surge protectors (specifically <a href="" rel="nofollow noreferrer">this</a> rated for 3,940 Joules and <a href="" rel="nofollow noreferrer">this</a> for 1,240 Joules).</p><h2>Seemingly fine...</h2><p>Throughout the next 3 months I did experience the same power flicker 4-5 times (none due to storms), two of them on the same day, but with no repercussions to my electronics. </p><h2>RIP</h2><p>Then last week it struck again and once more killed the power adapter (to the same monitor as before, ie: it killed the replacement adapter). Before declaring it dead I checked everything over, all the wires and connections were tight and no power was being drawn by the adapter (small green LED on the adapter brick itself is out). I did not bother calling the power company (I should have).</p><p>It appears that the same exact issue has occurred only this time with everything on high voltage surge protectors. It's worth noting that the power adapter that died this time was indeed connected to the weaker 1,240 Joule protector.</p><p>I rent part of this house so I am unaware of how much amperage the others consume, but I do know this is not a simple tripping of the breakers (since no flip of the breaker switch was required for power to return). The homeowners and 1 other tenant were not even home last week when my adapter died.</p><h2>This begs the question</h2><p>What is killing my power adapters? Is it a power spike or surge? An issue of drawing too much amperage from the circuit breaker? Something else?</p><p><strong>Disclaimer:</strong> <em>I do not fully understand electrical wiring, how the power grid works, the differences between voltage, amperage, watts, coulombs, and Joules but have a very basic familiarity. I'm more than willing to learn whatever it takes (and competent enough, I'd like to think) so please don't shy away from technical explanations.</em></p> not trace the packets to a specific gateway ip © superuser.comforAllBright<p>I try to make the OSX host-A to be a specific gateway for a Linux host-B.

It started getting an error on boot about having an issue with a PXE utility?? Walked them through getting to the BIOS and changed the boot order to have Windows Boot Manager be first in the boot order. As soon they saved and rebooted computer, it now goes to a black screen with no splash screens and no BIOS display. </p><p>I have researched the web and appears this has happened to several people (exact same sequence of events). I have tried pulling the laptop battery, removed the AC power and held the power button several times. Pulled the CMOS battery and left it out over night, tried using a USB stick that is flashed as a boot device and no luck. FYI I have tried tapping and holding every key known to get in the BIOS (F2, F10, DEL, ESC, etc.) and no luck. Nothing on the screen to indicate it is trying to boot. The power light stays on and the HD light flashes, can hear the optical drive spin up when first powered up.</p><p>This laptop was at least showing the BIOS and getting an error on a boot device until a change was made in the BIOS, so I would not think it is a hardware failure. From what I have read most of the time this has happened after an update to Windows 8. I know Windows 8 controls the BIOS differently now with UEFI computers and this one is a little over a year old so out of warranty.</p><p>Anyone have ideas of what to try?</p><p>Thanks,Steve</p> a 3 Antenna Wireless N Router work with only 1 Antenna? © superuser.comMilMike<p>I am using 2 Wireless G routers but am planning to buy a Wireless N network to get more speed.

(FYI I access Hotmail via POP. On Vista.)(Yes I already read the Help, FAQ, Release Notes, Bugzilla, archives and googled the web. Many reports, few solutions and none that work 100%.)</p><p>In the Thunderbird Bugzilla, there are many bugs over many years for 'duplicate email', but the main culprit for my issue <em>might</em> be <a href="" rel="nofollow noreferrer">Bug 608242 - "Hotmail still downloading duplicate messages"</a>. Then again it might not be, it might also be <a href="" rel="nofollow noreferrer">284526</a>, <a href="" rel="nofollow noreferrer">591334</a>, maybe 612136 or other. To get these bugs more prominence, register on Bugzilla and vote for them.There are many other manifestations of duplicate mail in TB, so do not start arguing that the culprit is Hotmail and not Thunderbird itself. TB should be able to handle this robustly, no matter how crappy Hotmail might be.The underlying root-cause sounds like the hash file 'popstate.dat' in which TB keeps a hash of message date, time, sender, subject etc. and checks it before downloading. Many of the Bugzillas suggest popstate.dat may be being corrupted, e.g. by (AVG) antivirus. There are also reports that filtering or attachments also tickle this.
