• AF842AW mini tower does not illuminate

  A newly acquired AF842AW desktop computer started OK and authorized preliminary, then locked up operations in scroll rapidly across the screen.  Could not access the normal Windows shutdown so eventually and reluctantly, I forced the computer off with the power button.  Attempts to restart now button power gives only the Red led lights up and beeps.  (A search found a thread of community with similar beep and LED light problems but his answers don't seem to adapt to my case)

  I have no user manual and have not been able to find one on the web.  (Complete HP recently supported this model.) So if there are flashing lights and beeps-based troubleshooting tips I can't find and understand them.

  I'd like to get this machine going again and asked that any help/advice that can be given.

• OptiPlex 745 Mini-Tower - GFX card options?

  Hi all

  I own an optiplex 745 Mini-Tower and I want to install a graphics card. I read the manual and it says that its PCI Express slot is 16 x but I could not find anywhere a response on whether it is compatible PCI-E 2.0 or 3.0. This makes the choice of a quite difficult graphics card. I read somewhere that if I install a 3.0 card gfx, it would be "backward compatible" feel, he would work on a 2.0 interface (isn't that backward compatibility option depends on the entirely gfx card?) Some cards him and others not so I'm not mistaken).

  So, this is the case with this model, or it is indeed a 3.0 interface?

  Could I install a 3.0 card gfx or 2.0?

  Thank you.

  PCI-E 1.0 or 2.0 are very good.  PCI-E 2.1 or 3.0 may or may not be backward compatible. Some R4 R5 R9 of R7 of Sapphire cards do seem to work in older systems like the precision, etc. 490.  I used an ASUS GDDR5 PCI-E 3.0 GT740 and it worked fine in my 745.

  The problem is that the profile for the 16 x power plug changes with version 2.1 and 3.0.  In addition, Sapphire will show they don't support UEFI BIOS systems with their R series cards.

  It is also why the older variety of version 1.0 or 2.0 cards often are not seen at all on the bus 3.0 on new computers.

  The Asus EAH6450 works very well in all models of Dell, in that I have tried.

  Not compatible with USFF or Micro because they have no slots.

  The only new parameter is the secure boot must be extinguished and CSM on for some cards to post.

  ASUS EAH 6450 SILENT card fits all models of Dell who have a Slot PCI - E, meaning that it does not work with USFF due to no expansion slot. The 6450 a 2 X the number of shaders as the 5450 doesn't.

• Mini Displayport does not not on the new Best Buy Yoga 14 (Yoga 460)

  Yesterday, I bought one of the brand new 14 Yoga from Best Buy, the one with the stylus, which is basically a 460 yoga.

  Mini Displayport does not work. Hook up a monitor makes the system to hang for about 15 seconds, and no screen is detected.

  All Windows and Lenovo software are up to date.

  I use a Mini DP--> HDMI adapter, but I've never had problems with it on other computers.

  I have ordered another cable converter and will try that tomorrow.

  Lenovo is aware of this problem? Is there a solution?

• Lights diagnostic OptiPlex 3010 Mini-Tower 3 & 4

  Hi all, I'm new to this forum. 2 years ago, I bought a dell optiplex 3010 mini tour, suddenly, it stopped working, I have no screen, no video or any kind of sound, the only thing it does is to turn on the lights of number 3 & 4 on the front panel. What can I do?

  3 & 4 usually diagnostic lights indicate a memory problem, see page 42 here:

  http://FTP.Dell.com/manuals/all-products/esuprt_desktop/esuprt_optiplex_desktop/OptiPlex-3010_Owner%27s%20Manual2_en-us.PDF

  First of all, try the following:

  Remove and reinstall all memory modules and try to start the system, to see if that makes a difference.

  Still does not start, remove all the memory modules [page 14] and then install only one module in the connector 1 and see if the system starts, and if the computer starts normally, reinstall an additional module.
  Do not start, move the module in slot 2 and still a time see if the system boots.

  Still does not start, then remove the first module, and using the other, repeat the sequence described above.

  Still does not start, purchase a new compatible memory module and try that.

  Then, if the computer still does not start, it is possible that the motherboard has failed and must be replaced.

• Mac Mini - Finder does not open

  I have a Mac Mini with os x 10.10 2014.  The boot disk was almost full and the finder does not open.  I open the iPhoto and deleted the pictures and then empty the trash in iPhoto.  By logging in as a different user, I see I have ~ 1 GB of space, but when I log on my main account and admin the finder does not always open.

  I read that it was a known issue:

  http://forums.MacRumors.com/threads/Finder-doesn.

  It is said to remove the .plist files, but I can't get to Terminal to do.

  Please advise, thank you!

  Edmund

  If you were able to connect as another user, the issue is not lack of storage - this is the same computer.

  Yes, your .plist file may be corrupt, or you could have an extension conflict that affects only your user account.

  Try the start mode by holding down the SHIFT key at startup. Secure boot is quite slow because the operating system does a lot of cleanup and verification tasks, so give it time. Once you're completely connected, restart normally.

• My original opening on a new Mac Mini installation does not work. I have the series or available

  Opening 1 and implemented to date are installed on a MAC Pro: 2 x Dual-Core Intel Xeon 2.66 GHz. memory 5 GB

  Software: MAC OS X Lion 10.7.5.

  Now, I would like to install Aperture on a new Mac Mini: 2.6 GHz Intel Core i5. OS X: El Capitan.

  All the series nor are available.

  But the Mac Mini can't find software to install, even if the disk is in the drive.

  Need your help to tackle this problem.

  Thanks in advance

  Opening 1 does not work on El Capitan. You need minimum Aperture 3 and which is no longer sold. Time for a new plan.

• Airport utility: green points on the AirPort Extreme & Internet; Mini Mac does not connect to the internet.

  Airport utility shows green points on the AirPort Extreme and the Internet, but my my Mac mini does not connect to the internet. IPhones and 2 portable Windows connect very well, and see all the devices on the home network. The problem occurred after that PSI has swapped an ancient for a Comtrend CT5072T DSL modem. I tried to stop and things start back up as if the installation of the internet for the first time. No joy.

  The airport connects using DHCP in Bridge Mode

  The router address is 192.168.80.1

  Address IPv4 is 192.168.80.2

  DNS server is the same as the router, but grayed out

  Mac Mini IPv4 Address is 192.168.80.3

  IPv6 automatically configures

  Also updated the firmware of the airport; no change.

  ISP guy was friendly but puzzled. He started at the top floor level Tech, so I do not know when I hear back.

  Any ideas to fix?

  Thank you.

  Hello

  Network preferences may be damaged.

  Open the Finder. In the Finder menu bar, click go > go to folder

  Type or copy paste the following text:

  / Library/Preferences/SystemConfiguration

  Click OK, and then move all files in the SystemConfiguration folder to the trash.

  Restart your Mac. See if that makes a difference.

  Your Mac will generate a new SystemConfiguration folder for you.

  Then open AirPort Utility located in HD > Applications > Utilitiies

  Make sure that both Internet and Extreme are green.

  

• End of 2012 the Ethernet Mini Mac does not connect

  Everything worked very well upward until a week ago.  I did all these recent software updates to cause problems.

  I'm running OS X 10.11.3.  I use wired ethernet.  My ethernet does not work.  Preferences network indicates that the cable is disconnected.  It is not the case.  I tried to use another cable and same results.  I have a managed switch and it still says that when the Mini is on that the port is turned on and has 1000 full duplex connection.  When I power down the port turns off indicating it is nothing plugged in, when I turn on it powered back upward.  Therefore, it is not as if the ethernet port has failed.

  I tried to renew the DHCP lease in network, deactivation and reactivation of the ethernet service preferences and still no luck.  Keeps coming up as ethernet is not connected.  I opened terminal and ran ifconfig and receive nothing.  I am unable to ping to any external site.  I am also unable to connect to my modem.

  Wireless works fine.  I have a second, identical Mac Mini connected to the same hardware via ethernet, which works very well, so it doesn't seem to be any hardware related issues.  I use all the gear from ubiquiti networks, 24-port POE switch and usg 4 router pro, all new age of 2 months.  This must be a Mac issue and has nothing to do with my equipment.  2014 mac Book Pro works fine as well as 2 iPad Pros and 2 iPhones though wireless connections for them.

  Any help is greatly appreciated.

  It happened to other institutions.

  Maybe Skype updated, but for some reason any small mini video that usually does not appear when someone has a webcam to the top most, just the usual widget that has the mute option and hang up.

  I tried to delete my settings and reinstall Skype and none has solved the problem.

• Mac Mini blocked, does not respond to the keyboard

  So, we have a mac mini since 2006. Since 2007, he has 24 hours a day.

  Now it has crashed, and while restarting it seems to be stuck at the gray screen with the apple logo.

  The circle under it is moving, it seems that it is still starting.

  I tried all kinds of different key combi any reboots, but nothing seems to work. Even the light caps lock does not work on the keyboard.

  Have you tried to dismantle the mini and put back together. No luck.

  Can someone tell me what is happening? Would appreciate your help!

  Best guess would be a failing hard drive. You can try to boot from the original CD/DVD comes with your Mac or DVD for an improved version of OS X, run disk utility to repair the internal disk partition.

  Note: It is advisable to restart your Mac on a regular basis as opposed to she works 24 hours a day for 8 years.

  It also helps to provide as much information as possible on your Mac. There are 4 different models MacMini that can be described as of 2006, and you do not identify the version of your OS X.
