• 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.

• G6 caps lock flashes continuously, nothing on the screen

  Hi, I have a HP g6-1325sa had a problem which had to replace the fan.

  However since then nothing appears on the screen F12 has an orange light and the caps lock continuously flashes every 2-3 seconds. This isn't a blinking code it does this constantly.
  So far, I have tried blocking the vents and leaving the laptop that works for more than an hour, as I've heard can be caused by dry solder joints. I have also tried to replace the motherboard and twice managed to get a cursor blinking on the screen but niether of those moments a normal startup is possible that the HARD drive has been disconnected on both of these occasions, the first time that it happened, I had just disconnected power and battery and power and hold for 30 seconds I'm guessing it's a cmos reset.

  the only cause I can think is that the processor is cooked when the fan has been replaced, but who had already paid for another motherboard I would like someone to confirm what it means when the caps lock flashes constantly and if there is another way to fix it.

  Thank you very much in advance for any help

  Solved this problem where everyone sees the same behavior.

  CPU replaced and he started to ask right now, it seems that my predecessor Cook the processor when they changed it is fan.

• Compaq Presario CQ62-412NR does not start. Caps lock flashes.

  The LED caps lock flashes repidadly with long breaks between each blink, the wireless light and constant and the adapter LED is steady. I read blink codes and determined, he was the processor, but the problem persists after him substituting a known good. I finished the resets power to clear the bios before and after the change of the CPU. I also tried to replace the RAM. Anyone here have a clue whats going on?

  This looks like a problem with the motherboard if you already replaced the CPU and RAM.
  
  It would be probably cheaper to replace the unit at this time only so, fix it or replace the motherboard.

  Hi Steve,

  Unfortunately, there are many possible causes for this problem, I mentioned the video chip as possible example given the symptoms you describe - you need get the machine examined to ensure.  Failure of a component is often extremely fast, insofar as it works one minute then is not the other.

  Dear customer,

  Welcome and thanks for posting your question on the Forum of Support HP

  It seems that your laptop has a blank screen and a blinking/flashing CAPSLOCK all the time

  If the Capslock LED flashes 3 times this means "Non-functional memory error", in order to solve the problem, replace the card memory

  Note: If you are comfortable open Notepad, you can check how much you have memory module. If you have 2 sticks of memory, you can test one at a time on the two slots individually to check if the fault is with the module module slot or memory memory your laptop [repeat the same steps to test another memory module]

  If you find the above steps difficult and that it is a hardware problem and I recommend you contact HP Support by phone for further assistance immediately to get your diagnostic Notebook and repaired by an authorized HP Certified Engineer

  You can also check your warranty here to check the status of the guarantee

• Satellite A305-S6898 - half black screen at startup

  I bought this laptop in early March and had to return to store due to a problem at startup when half of the screen would be black on the Windows login screen. They ordered me a new I got about 3 weeks ago and I used it for about a week before I had the same problem of a half black screen on startup.

  Now he has been running really slow and there is a time, I've had it freeze on me and my screen turn into a bunch of colored lines.
  I had to reboot in safe mode and run a virus scan just to make sure it wasn't my problem.

  I do not download anything on this computer other than basic messengers and photo editing programs.
  I have a HP MP7170N desktop computer which I use to download everything that seems to work faster than the laptop and I use photo, download torrents programs and store most of my pictures and music on this one and it has only 1 GB of memory compared to this the 4 GB.

  What is the problem?
  Anyone have any ideas as to what I can do.
  I can't really go back to the shop because they give only a grace period of 14 days for returns.

  Doesn't look good for me it sounds a bit like graphic problem.
  Before contacting a professional Toshiba authorized service provider would be, it would be interesting to know if you have seen improvements after recovery procedure and BIOS updated.
  I think you n t get a recovery disk because you can create it using the verification of software preinstalled Toshiba manual how to create the recovery disk

  If, after installing new check usability of portable and so similar issues still persists.
  If nothing will change it s is strongly recommended to communicate with an ASP.

• Black screen on startup Satellite A80

  I get a black screen at startup what is the problem and what is the solution for it? It might have something to do with the cold?

  Hi poly

  Please put more details on the problem, because it s not easy to say what has happened without any detailed information. You hear the operation of the HARD disk or fans?
  Switch you to other devices to display, before this problem occurs?
  Unfortunately it FN + F5 key combination doesn't work if the operating system has started so it could be a malfunction of the equipment. I don t think you can solve this problem by yourself. In this case, the only way is to contact the service.

• Satellite A100 - black screen on startup

  For two days my laptop Toshiba A100-495 / model-No. PSAA9E-18F047GR / Y6065357Q with Windows XP SP3 serial shows a black screen at startup. There is still no picture Windows startup.

  The laptop is all starting, but after finishing and be ready for use, the screen is always black. When I am pressing Fn + F5 keys, the desktop appears.

  The black screen is only starting cold after stopping, not awareness of standby or pause.

  > When I am pressing Fn + F5 keys, the desktop appears

  It seems that the display output is set to external monitor
  You see the Toshiba start screen if the laptop is connected to the external monitor?
  Check it!

  In addition, I am agree with Akuma BIOS should be the default value.
  To access the BIOS F2 press while turning on the laptop. I hope that you can do this then press F9 for default settings and then exit the BIOS save settings.

• B540 TDR and black screen on startup

  Hi all, I bought a B540 in April a power works fine until end of July when it began to show the error "display driver has stopped working and has recovered." a few days later I let him (I have need as a wifi station to connect devices remove) and after a few hours of work, when I came back, the screen was off and there wa no way to turn it on. I press the power button for a few seconds to turn off the pc and he died. When I turned on, the computer started but the screen is off (not the 'lenovo' logo was shown on the eve) but everything else seemed to work (play plug/unpluging usb external hard drive the sound of the carachteristic). I turned off again and wait ten minutes before the market again, this time above the 'lenovo' logo was shown, but it seems that the pc failed to boot win 8. I unlplugged everything, removed the power cord, wait an hour and after that all started ok but the error message "display driver stop" was still there. After this date the computer randomly starts ok or with the screen. Given that I do not use it intensively Isuspected some windows update to cause this strange behavior and I'm trying to use a point of restoration, until July 17, but the problem was still there. Then I removed all recent windows update of June on, and I realized that in one case, it was not possible (i.e. the "remove/uninstall" button not showed that KB). I googled around and found the subject KB has been reported to broken system and the only way to react was to use a DOS command to reatore a new installation of the system. I did and actually everything works ok for 2 days (one day, I actually use the PC all day to upload stuff to iternet it to work). Unfortunately, after that day, everything seems to repeat: new 'pilot not resposinding to display' and a black screen at startup.

  Please consider that the system is quite new and clean (only 3/4 months of life) and everything works fine until end of July. What do you suggest me?

  
  

• Power outage during Vista SP2 install; black screen on startup of the PC

  Hello-

  I have a PC desktop Gateway which is no longer start after a power failure has occurred during the installation of Vista SP2. The computer displays the progress at the bottom indicator, then, before that can display the login screen, the screen goes black, with a white cursor. CTRL-Alt-Del and Ctrl-Shift-Esc do nothing.

  I tried without success to the following:

  * Safe Mode/Safe Mode control guest - boots to black screen new
  * Startup Repair - told me there is nothing wrong
  * System Restore - tells me there is no available restore points
  * System restore the OEM DVD - can not find hard drive
  * Re-install this is disabled because I can't start Windows Vista-

  There are * all * options other than wiping the disc/lose all my data? The PC is in a remote area and backup drive is not an easy thing to achieve.

  The PC is no longer under warranty of the bridge, and I understand that Microsoft supports is no longer installs OEM of Vista.

  Can anyone help?

  Thank you

  I can tell you how to make bootable disks, but you already have a disk.

  He has changed since good means of XP repair install from disk by booting from it.

  I would add that info to disk Bootable repair, just in case your DVD is a factory of one computer.

  http://www.Vistax64.com/tutorials/88236-repair-install-Vista.html

  It's Vista only repair installation option these days.
  It must be switched on!
  Not much use, is it!

  Good luck with it.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  Download the ISO on the provided link and do a repair of the disc.

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

  When you have changed that, insert the Bootable disk you did in the drive and reboot.

  http://www.bleepingcomputer.com/tutorials/tutorial148.html

  Above information shows what the process looks like and a manual, it load the repair options.

  NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

  Read all the info on the website on how to create and use it.

  http://NeoSmart.net/blog/2008/Windows-Vista-recovery-disc-download/

  ISO Burner: http://www.snapfiles.com/get/active-isoburner.html

  It's a very good Vista Startup Repair disk.

  You can do a system restart tool, system, etc it restore.

  It is NOT a disc of resettlement.

  And the 32-bit is what normally comes on a computer, unless 64-bit.

  See you soon.
