• HP probook 4720 graph blue screen of death

  I have a HP probook 4720 s (product #: WT238EA #ACQ). I upgraded my 6 GB RAM.

  My problem. The other day, I was busy playing a game when the computer froze, then off while she turned on a small blue screen appeared briefly. I restarted the laptop and everything seemed fine, I left the computer for a few minutes and when I came back the screen was turned off completely but the computer was working normally. No key or anything would be to put the screen back on.

  After this event I tried to put the laptop on it would start everytime (HHD spin, CPU fan, HARD drive light flashing for a little and then stop, but the screen remains completely black with no blue backlight). I tried the hard reset and a number of other things like checking if the RAM has been correctly connected, the screen stays off.

  I decided to connect the laptop to an external monitor and I could finally display on the monitor, but still, it would display on the screen of the laptop. After loading the windows emblem the dreaded blue screen of death appears with a STOP error message 0 x 00000116 who, after some research, seems to be the graphics driver. After the start of the security system and roll back the standard graphics driver VGA adapter of the windows system 7 was then able to boot into normal mode. I tried to reinstall the HD 5470 graphics driver but the blue screen of death continues to be displayed. I completely rebooted the OS without result.

  I unplugged the screen of laptop computers to the motherboard without the graphics driver loaded, which did not cause a beep but on the monitor external when I plugged it. I tried the same thing with the loaded graphics driver, still no beeps were heard and when I plugged the external monitor blue screen appeared.

  Tests I had tried, I think there must be a problem with the graphics card itself as the blue screen of death poster only when the graphics card driver is loaded.

  Could you please say how you feel, I do, a help on this would be much appreciated. I have appolagize for the long message.

  Kind regards

  Problem solved. The MOSFET chip had stopped working, a fast replacement and the screen and everything worked perfectly!

• How to clean the MacBook Air 11 "display?

  What is the best way to clean the MacBook Air 11 "display? I'm afraid to use a liquid cleaner for these surfaces, but it's the best. In my case, I only clean with a soft, dry cloth. Any suggestion?

• How to clean of the Mac server permissions issue

  I'll have some very frustrating problems with permissions in the Group shared on mac server folders. When I create a new set of permissions at the top of the folder hierarchy and spread so it seems just create another copy permissions in all folders under the root rather than deleting the previous permissions and write those I want to set up. In other words, I end up with several sets of permissions by user for each folder and file.

  So the question I'm asking is how to clean all these permissions to all folders and files and start again?

  The main issues I'm having, it's that I have even with full administrative rights'm get denied permission to open files and save them to the server.

  My server is running OS X El Capitan 10.11.4, version 5.1 Server mac

  The simplest (and usually faster) is to clean up you permissions to use the chmod of the Terminal command.  If your ACL multiply in an uncontrolled manner (please not that some versions of Office for Windows, used to cause this) you can quickly delete all the ACL, and then start again.  To do this, follow these steps:

  1: stop all services of files to ensure that no one is change data while you work on it.

  2: remove all ACLs by using this command (replace with the actual path to the data):

  sudo chmod-r n/path/to/your/share

  This will remove all the ACLs for all files and folders/path/to/your/share and recurse to everything in the folder.

  Now, if you think that your POSIX permissions are Leech, you can also reset this with two orders of the handle.  To restore all standard directories umask, use:

  sudo find/path/to/your/share-type d - exec chmod 755 ().

  To restore all files standard umask, use:

  sudo find/path/to/your/share-type f-exec chmod 644 ().

  Note: Your permissions model may be more restrictive and some workflows rely on the limitation by POSIX.  If so, these commands do not be what you want.

  And there you have it.  The three commands above can remove all ACLs and set all folders to 755 (drwxr-xr-x) and all files to 644 (- rw - r - r-).

  Once you reset data, return to Server.app > sharing or.app > server > storage and assign your permissions.

• How to clean the dirt hard on coverage of the mac?

  Hello guys.  I have a mac here, which I use for work.  Hands may become very sales sometimes which is how dirt happens on my mac.  The cover of the screen, where the apple logo is, where it's the dirtiest.  I tried to clean it with a nonabrasive cloth with wet water, no luck there.  If I had to use my finger and keep rubbing, would come out a bit of dirt but that would take forever.  Anyone of you have a better solution on how to clean this rough dirt of my coverage?  Apple offered no use of solvents, sprays or abrasives to clean.  I would like to have the lid nice and clean without damaging the sweetness of the coverage.  Thanks for reading!

  You could spray a mist of iKlear on a cotton cloth.

  There have been reports of this iKlear damage some of the coating of screen initially on retina patterns-

  No report of it damaging the aluminum housing.

• Portege R630 - how to clean cooling system?

  I've had my Portege R630 for a few months now and I love it. HOWEVER! Small snag. I live is a House with 3 other people and it gets pretty dusty. Not really bad, but I'm not going to lie it's almost clinical environment. Now, my R630 started having what I think is 'too hot' for processing power used.

  Currently, my CPU usage is between 10 and 20% according to time and PC Health Monitor, my system CPU are 60% and my fan runs at 50-60%. My system has the Core i3 2.53gHz processor, unusually warm for the system?

  And if my guess is so dust is linked. But how to clean the radiator on it? It's not really normal. I can get my hands on a can of compressed air, but because the fan is so far away from the CPU, the dust could be everywhere on this side of the laptop. What is the best way to get clean?

  Thank you very much!

  Hello

  Cleaning of the cooling system is not complicated. All you need is to jet of compressed air that you can buy from every computer store I think.

  Before to start the cleaning procedure remove the AC/DC adapter and battery. Turn the laptop around, then blow air gently and shortly into the holes in the case. This will blow out the dust.
  As you can see is very easy and it of not necessary to disassemble the laptop.

• Satellite L350-24U: how to clean the keyboard after having poured orange juice

  Hello out there.
  I spilled my L350-24U with Orange juice.
  Now, I have 4 keys to self-retaining :-(

  Can someone tell me how to clean the keyboard without damaging the laptop?

  Thanks in advance.

  Hmm, it's still a stupid situation
  Usually you can remove the keyboard of the laptop very easily.
  The keyboard is fixed with screws hidden under thin plastic cover near the line of F1 - F12 key.

  If you would remove plastic this cover then you would be able to remove the screws as well. Then you could lift the keyboard carefully and could disconnect the flat cable of the keyboard and the motherboard.

  Notes; two small latches on both sides of the connector must be moved in order to disconnect the cable.

  Then you could remove the keyboard and could clean it with a damp lint.
  PS: the caps can be removed too.
  But be very careful. You must raise the CAP to get it for free.

  There are many videos on youtube...

• Equium A60-155: how to clean the fan?

  This isn't a problem as such, more than one request. How do you clean the fan? A litle while ago my laptop kept turning off itself, and it turned out to be part of the problem I the fan was clogged so I was wondering if anyone knew how to clean so I can myself sorting in case it happens again. Thanx

  Hi Jemma,

  The problem is that dust is sucked into the fans and is then trapped in the radiator CPU effectively blocks.

  A good way os compensation this accumulation of dust is to use a hose of vacuum cleaner against the aspiration air grills so that dust is sucked in. Just put the hose against the grids of aspiration air for a few seconds and block any gaps around the pipe with a cloth.

  Kind regards
