There is one advantage. The dog eating the homework it too old to be believed these days. Now the excuse is, "My mother didn't pay this month's Word rent so it won't let me print" |

I am out of this thread. You are impossible. When e say it is dual band it is. If you can't believe why don't you ask HP? So much hassle buying a laptop. |

I had posted a screen shot of all the information that HP provides: But that's all I have. The problem is, if I look at a DELL or Toshiba or Lenovo laptop, I'll still have the SAME PROBLEM of figuring out whether it has 5GHz or 2.4GHz or both, from the specs. So, it behooves us to be able to read the specs. From what Jeff said, all I can tell is (is this correct?): 802.11 a ==> 5GHz only 802.11 b ==> 2.4GHz only 802.11 g ==> 2.4GHz only 802.11 n ==> 2.4GHz only? 802.11 ac ==> 5GHz only Basically, if it has an "a" in the description, then it's 5GHz. Otherwise, it's 2.4GHz. |

Intel 7265 BGN + Bluetooth Version 4.0 Would it be safe to assume this has *only* 2.4GHz? 2. Intel 7265 AC/B/G/N Dual Band Wireless + Bluetooth Version 4.0 Is it safe to assume this has *both* 2.4GHz & 5GHz? |

Office 2007 will run on Win 10: <http://www.microsoft.com/en-in/windows/compatibility/CompatCenter/ProductViewerWithDefaultFilters?TempOsid=Windows%2010&Locale=en-in&Architecture=X64&TextSearch=microsoft%2Boffice%2B2007%2Bstandard&Type=Both&CurrentPage=0&TotalPages=1&ShowCriteria=0&SortCriteria=Relevance&Compatibility=Unknown&LastRequested=14> Grab Belarc Advisor, run it on the XP machine, and PRINT the results. Somewhere in there, it will have the various serial numbers needed for the installation. If the ancient XP machine crashes without a backup or a list of serial numbers, she will not be able to reinstall Office 2007 on a new machine: <http://www.belarc.com/free_download.html> >so, it costs her $140 for 7 years (or 10% less with the teacher discount). >It's a no brainer, to me; but this isn't the question in the OP, so it's >just an offshoot discussion which isn't at all confusing to me. Right. With only one machine, Office 365 doesn't make economic sense. I was thinking of a skool, not an individual user. I still think the various alternatives (Google Office, LibreOffice, etc) are worth investigating.

It tells me that HP marketing is clueless. The assumption is that anything that does "ac" will also do the lesser protocol of "a". Since "ac" only works on 5GHz, and nobody today makes a 5GHz only radio, it's a fair assumption that anything with "ac" will be dual band. However, that's an assumption. I tried to find the Intel card used in the 15z and failed. You'll probably have to ask HP pre-sales, this I predict will be clueless. You might try the HP support forums. <http://h30434.www3.hp.com/t5/Laptop-and-Notebook-Computers/ct-p/Notebook> -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
| N_Cook <diverse@tcp.co.uk>: Sep 08 02:37PM +0100 Flashing r is lack of current, needs 9V , 700mA minimum. Repaired that pcb and another problem under keyboard. One bank of keys inoperative. Originally found the break on the common line to keys 25 to 32, then it disappeared. Could not find the break so will run a bypass wire. Neatest way , for a good soldering point on wide trace of the commons, is punch a hole through the pink silicone mambrane and pass a wire through that and down to the ribbon connector. I asume the hairline crack is somewhere along the 400mm or so run of fine track. |

Tony, Not all home theater receivers provide video output in a different format than the format of the video input. My home theater is a Best Buy Insignia unit - which came with all the speakers; a unit that meets your description of "entry level HT receiver with speaker kits in a box". The receiver appears to be a re-labeled Onkyo unit. I have HDMI, component, and composite input sources connect to the HT receiver. However, I found to my surprise, consistent with the user's manual, that the receiver outputs those video sources only to the same format output jacks on the receiver. Fortunately, my HDTV has sufficient input sources of each type so I don't have a problem. In summary, my HT receiver won't output a composite or component video input signal to the HDMI output jack. If an when I ever replace my HT receiver, I'll make sure the replacement can do that. Peter |

Peter Your only choice is then using little converter box. 3 cable component cable/digital audio in and HDMI out. Some time ago wife won a HT in a box, LG brand in a raffle. It has HDMI o/p to HDTV. Since we did not need it, I sold it to a neighbor's kid for 100.00. I never like Onkyo receivers. Their power supply seems to be little under rated. Unit runs always too hot to my liking. I was a fan of Denon stuff. Now I moved up to Anthem receiver and all Paradigm speakers except PBS 250W 12" Woofer. When organic TV price comes down I'll upgrade TV set. |
