• HP envy 15 t-j100: screen went white and caps lock flashing after update bios!

  Update my bios to the latest version via app HP support and after it restarted the screen are empty and the caps lock flashing! What can I do about it?

  Thank you for visiting @omidmiri.

  Here on the Forums of HP's Support, you have access to many members of the community with solutions and suggestions to help. I understand that you have a problem with a black screen and the Caps Lock LED flashes after a BIOS update.

  The led near the caps lock shift keys and numlock blinks if a fault is detected during the boot process. The LEDs flash multiple times in a sequence and then stops.

  Please try to manually perform a BIOS recovery, as follows:

  1. Turn off the computer.

  2. Plug the laptop using the power adapter.

  3. When the computer is always off:

     1. Press on and hold the Windows key and the B key at the same time and then press in and hold the power button on the laptop for a second.

     2. Release the power button and the keys.

  By following these steps, the BIOS will reach the EFI partition in order to recover the BIOS to the latest known version of the BIOS from the hard drive.

  Hello

  First of all, regarding the manual of maintenance on the link below--remove and reposition your bars of memory.

  If the above makes no difference try the following.

  Again, regards to the manual on the link below, delete one of your modules from memory and then see if the computer will start.  If it doesn't, try the same module, but in another location.  If it is still won't start, try the other memory module in both slots, to see if any combination will allow the laptop to boot up normally.

  The procedure for withdrawal of these modules is detailed from Page 63 of your & Maintenance Guide.

  Kind regards

• HP Pavilion x 360 has the white screen and LOCK SHIFT key flashes

  I recently got a new laptop from 13-inch HP Pavilion x 360 a week ago. It worked well and I loved. six days after that I started to use it the screen goes black while I watch a youtube video and the mahcine started his strange. I use the power button to turn off the laptop, and then restart it. Laptop works very well and I continue to use it on another fifteen minutes until I close and start loading. 40 minutes later, I opened the laptop to find that the screen does not light and the CAPS Lock key blinks once in a repeating sequence. I didn't do anything the screen lights up. After some research, I think it's a potential CPU issue. What are the reasons as to why it happened to my brand new laptop?

  Hello

  Seems that there are problems with the files of GoBack.

  Try to boot in safe mode and remove the Norton System works from your laptop ;)
  If this does not help, you will need to recover the laptop with the recovery CD Toshiba delivered!

  Also I recommend to visit the Symantec support site and to check the solutions to the problem with the Norton System Works programs

• HP Pavilion G6: Black screen, Cap lock blinks and turned on wifi in orange

  Bought this non-functional computer for $40.  The screen is black, the caps lock flashes and the wifi light is lit in orange.  At the time, we could hear all the computer starts, the fan would go, the drive initialize... so I watched a few videos on the problems of black screen on youtube, he got up and running.

  However, it is a tease, she worked for less than a month.  I does not solve the problem which has been heat.  I buy quadfans for going below but they turned off during the night and should not have.  I have the computer to check the updates at 03:00, so the computer would then come and fans wouldn't.

  Well, the black screen problem is backkkk.  The fan don't dΘmarre, try the hard drive.  This time nothing is set.  Ive pulled the motherboard to replace the fan.  I replaced and updated the hard drive and memory... still nothing.   It also has a new battery and power cord.  Any suggestions as to what may be the problem?

• Black screen, caps lock flashes on startup

  Dear everybody. I know there are already a lot of similar topics, but none seem to portray exactly my situation, so I hope someone will be able to land a helpful hand.

  Then. A few months ago I had to move to Japan in my country (Italy). The warranty on my HP dv7 6189 sl expired while I was here, but since my laptop was having really bad cooling problems, I have documented my self with videos and guides to the internet and everything I coul find and decided to take it apart myself. I cleaned all the dust from the fan, the basic form of thermal paste on the processor and the Ati HD 6770. Then again once, back to paying attention to put it all together as it was (HOPEFULLY). Anyway, when I tried to start on the laptop, I found it now black screen guard. The light F-12 (wlan connection) continues, keeps flashing orange (like no wi - fi connection) and the CAPS LOCK. It seems to me it blinks THREE times before stopping a few lil lil and then repeat the cycle again. Anyone know what can be the problem? I'm desperate... Thanks in advance...

  Hello

  Based on the codes of following indicators:

  http://support.HP.com/us-en/document/c01443366

  You must:

  (a) reinstall the memory.
  (b) If you continue to experience this error code after the reinstallation of the memory, the problem may be with the memory itself. Grab the new memory of the computer, put back original memory in the computer, and then test again it.

  Good luck.

  PS we have a rule in our data centers: do not touch the machine without a static Anti bracelet.

  Hey Hey Hey Doc K whadu say?

  I solved my problem;

  the problem was owner and permission on my programs, all users, the program data and my programs (86).

  As I type this i / m re - run SFC/verify only and a big pile of sucessfully some updates installed.

  What have I done? I took possession of the special directories above from "TrustedInstaller".

  Even when owned by TrustedInstaller, it does not have permissions. Some places I found rejection specific to the owner of the network.

  -What happened? Do you have a trusted Installer get stuck Mid-install?

  I took possession of SYSTEM, and made sure the CREATOR had every right, as in the SYSTEM and

  USER, AUTHENTICATED USER. I was perhaps too broad.

  I took possession, and then all of the repressed, updates windows are presented themselves to install,.

  and I expect /VERIFYNOW SFC before as I mark this as running.

  I'm fairly certain VS2008 and VS2010 now repair and install.

  Hmmm... always to see funny error message in SFC...

  We need a tool to give an overview of a directory tree ownership and permissions.

  The laptop is only 4 months old and I am very annoyed at this subject - also call support Toshiba does anyone know of another option?

  Hello

  > The laptop is only 4 months old
  In this case, you must contact an authorized service provider because your laptop should be under warranty and so repair should be free.

  Have but before moving on to an authorized service provider you tried to reinstall the notebook using the Toshiba Recovery disk? If this is not the case, check this please!
