• Reset password Bios EliteBook

  Can someone help me in resetting the Bios on my Elitebook 8470P password?

  Product number is B2F97EC #ABA

  Operating system is Windows 7 Pro 64 bit.

  I got the file smc.bin Support HP to reset the password on my Elitebook 8470 P today.

  After that, I just copied the file on a bootable USB and booted the laptop by keeping Windows Key + up / arrow dn, then press F10, select reset password.

  It worked like a champ, I think your laptop should still be under warranty for this service, also level 1 services will not be much help, you will need to ask the file and request that they raise the service call.

  Hope this helps others in the future.

• Fan will not go at full speed on ProBook s 4720

  I have a notebook ProBook 4720 s, Windows 7 64 bit

  The problem is that the fan on my computer always remains at minimum speed and the computer warms, the fan does not accelerate to full speed. The computer is really hot ~ 70 ° C. The problem occurred when I updated the bios to its latest F.20. I think that there is a bug with this bios - that the bios will not control the fan properly. This type of laptop has a history of bugs in the bios: the original bios does the fan run all the time at full speed which has been resolved with a bios upgrade.

  This bios came with a note that I can not downgrade to an earlier version which worked well. So my question is, can I expect an upgrade of the bios for this computer that could correct the error.

  There is a temporary workaround solution. only do so at YOUR OWN RISK.

  This procedure works only on the ProBook s 4720 bios F.20. DO NOT TRY THIS METHOD ON OTHER MODELS!

  It only works when the laptop is on AC POWER. Download 'read and write utilities' http://rweverything.phpnet.us/. run the program, then click the icon of the EC (embedded controller). in the on-board controller window that opens, you will see a matrix of 16 x 16 = 256 numbers that choose the "05" version in the column and row "D0". This number has an offset address 213 (in dec) and probably a value of 1.

  (If you do not find it do not attempt to change a number at random, sound risky)

  Change the value to something from 0 to 70 (don't exceed 7F) and the fan will speed up the desired value.

  also, don't change the other values - risk of damaging the material

  the procedure must be repeated every time you start

  This procedure works only on the ProBook s 4720 bios F.20. on other models, the offset is different so don't try not not this method!

  do it at your own risk only

  the heart of the problem probably lies in the bad DSDT table (which came with the bios), but I guess that you would need an expert to fix it.

• Apple tv 4G - no charge aps and keeps resetting

  HI - I've just set up my new apple 4G on my existing apple account and I am surprised to see that there is no aps loaded on the main screen as it is with my 3G (e.g. ESPN, netflix, NHL, HBO, etc.). There is only standard he films/TV/Aps/photos/itunes bar and below this research alone, computers and settings.  Anyone know how to get this laoded up?

  In addition, the screen keeps resetting back (expel) to the main screen when I go in the options.  Not sure if thisnis associated with the foregoing.

  Any help much appreciated.

  Hello. There should be an app store on the home screen. You can use it to download applications for the services you want to use. It's a little awkward at first, but this means that the applications are easily updated and new ones can be added without updating the whole system. The whole system is very similar to an iPad or iPhone now.

  Going back to the home screen, the remote Menu button actually works as a button 'back', and you can save on an application on the home screen. There's a line here https://help.apple.com/appletv/ user guide, and you can also download in iBooks.

• Reset password BIOS EliteBook 8540w

  Hello

  Anyone know how to reset the BIOS password on a laptop computer without knowing the password?

  Thanks for your time

  Remove the RTC battery, main battery and the adapter. Press and hold the power button for 30 seconds and let the laptop sit for at least 20 minutes before inserting battery RTC back in. Install the main battery and the adapter.

  When you initialize it ask for load default BIOS settings, use your arrow keys and enter to do.

  

  The RTC battery is indicated by the red arrow and is behind the memory Bay door.

  Here's where I got the picture from.

  http://h20574.www2.HP.com/default.htm?lang=en & CC = US & hpappid = psml

  Remember to reset the time and date, if you do not have this Windows will think that you have a non valid copy.

  Next time you start, start to type the f10 key immediately to enter the BIOS to reset the clock and date. You can do it with in Windows, but I think that it is better to do it in the BIOS.
