  Hello mpm068,

  Thank you for using communities of Apple Support.

  Since your iSight webcam works up to the time that your Mac goes to sleep, I would like you to start please help desk trying to replicate this problem then to reboot in safe mode:

  1. Choose the Apple menu > shut down.

  2. After your Mac stops, wait 10 seconds, then press the power button.

  3. As soon as you hear the startup tone, hold down the SHIFT key.

     You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

  4. Release the SHIFT key when you see the gray Apple logo and progress indicator.

  To exit safe mode, restart your Mac, but no press during the startup.

• Pavilion dv9810us: computer HP Pavilion dv9810us laptop will not start

  Reminder: a few days before my laptop does not start up, all using the laptop, the screen has become, I guess the technical term would be 'nuts': horizontal lines an inch in height, made of blocks quickly black and white, all changing left and right, and I could see my spreadsheet in the background.  Could not do something about the problem, so I rebooted and it worked fine.

  Then a few days after that, I tried to turn on my laptop, and occurred the following:

  (1) blue illuminated switch, control all the keys lit in blue (volume, skip, repeat, DVD...), fan began and heard the dvd begins to check for a disc.  This lasted for about 2 seconds.

  (2) off laptop (all lights extinguished, no fan noise or a dvd).  This lasted for about 5 seconds.

  then it would just repeat steps 1 & 2 times: start 2 seconds, stop for 5...

  Steps that my work to correct (without success):

  -J' I disconnected and removed the battery.  Let stand a few minutes.  After I have inserted the battery and reconnected, I pressed the power button.  Same 2 steps as shown above (lit for 2 seconds, turn off for 5, repetition) happened.

  -saw a post on the site of HP on a hard reset.  so I unplugged, removed the battery, which is held from the Start button / stop for 20 seconds.  then replugged (without inserting the battery) and power on.  Same 2 steps above happened (lit for 2 seconds, off for 5, repetition...).

  -J' I reset memory as someone on the HP Board has suggested:

  (1) remove the two memory, then replace both in the correct order.

  Result: same problem (2 seconds 5 seconds, repeat...)

  (2) remove the top memory (1 GB), bottom (2 GB) by leaving in place.

  Result: same problem...

  (3) place 1 GB memory on the bottom, nothing over the top.

  Result: same problem...

  From the above information, no idea what the source of the problem is, and how to fix it?

  It would be to remove the motherboard and "re-invest" the video chip with a heat gun. Configure you with a shield from sheet aluminium with the chip pushing through like dessert in a TV dinner. There are many tutorials online, but like anything else go you better the more you do and the first time is risky. Repair shops using a better process called "reballing", which is basically rebuild the chip and requires hardware, that no individual can afford to have.

  Access to the old hard drive is easy. Physically, remove it from the machine.

  See 02:20 in. You must remove the plastic adapter for in standard SATA ports. You can leave it in the basket after removing the plastic adapter bar. Then use a usb to SATA adapter and you can plug the old drive on USB ports on your computer again, and it will appear as a USB key where you can copy and paste things out of it to the new PC.

• HP Pavilion g7-1261nr turns on but the screen remains blank

  I turned on my HP Pavilion g7-1261nr the other day, and the fan ran hard, as well as the caps lock and number lock LED flashes once every two seconds. The screen remains blank during the process. Could someone help me with this problem please?

  PcMatic I invite you to read the links provided, because they are there to help.

  If you entered my link, you would have seen this:

  Caps Lock/Num Lock LED component tested error Condition

  LED flashes 1 time CPU CPU not functional

  2 times for BIOS BIOS corruption failure LEDs blinking

  LED flashes 3 times non-functional Memory Module error

  LED flashes 4 times Graphics Graphics controller not functional

  Map of 5 times the system board failure system general LEDs flashing

  Authentication failed for the BIOS BIOS 6 times blinking of the LEDs

  According to the times that they blink, of what I mean, it's once and then a pause. Which would indicate that the CPU is broken.

  Only a repair can fix that.

• Laptop will not start light caps and seeing flashing Num

  My Ts2-1375dx does not start after I have stop and he turned his back. I get the cap & num lock lights will blink once. I remove the power cord, battery and devices all connected, press and hold the button on to 30 seconds, reconnect power and then try to start again. Although it works (perhaps after tests 1-3) I think not that this is the way you should have to start the computer. I also see a lot of the same problem with the solution is the method I use. WHY IS THERE NO PERMANT SOLUTION?

  RESOLVED: I have disassembled the computer, removed from motherboard and heated the motherboard with a dryer of hair, concentrating on the CPU, gpu & Southbridge chips one by one. I warmed up each chip and pushed the chip socket to reinstall and now it works without error.
  
  I now use a portable fan under the laptop to try to keep cooler so that it will not happen.

  I can't windows to stop coming on and asks me to install the desktop business drive. It starts as soon as I connect and will not stop, interupting everything what I do online

  Hi marcus,

  1. What is the full error message that you receive?

  2. have you recently trying to install a program on the computer?

  Method 1

  It is possible that some third-party programs installed on the computer is causing the problem.

  I suggest that you perform a clean boot and check.

  To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  See the link below to learn more about how to clean boot.

  Reset the computer to start as usual

  When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

  (a) click Start, type msconfig in the search box and press ENTER.

  (b) If you are prompted for an administrator password or for confirmation, type your password or click on continue.

  (c) under the general tab, click the Normal startup option, and then click OK.

  (d) when you are prompted to restart the computer, click on restart.

  Method 2

  If the previous step fails, then repair Microsoft office on the computer and check if it works.

• My pavilion G6 - 1210 SA goes in but the screen is not

  Hello

Out and adapter and the second fact 30 thing that did not work, I tried without the battery and still nothing at one point it seemed that updated operating system running but the screen does not (windows 7) any help would be great because I have a lot of work to do on my laptop

  Hey AJ2106,

  First of all, I wish you welcome on the HP Forums!

  Like your laptop is by train (heard the noise of the fan and LED is lit), but the screen remains black, I suggest you to watch the following document 'computer won't start (Windows 7, Vista, XP)'. Now, this document you have already done the hard reset so you won't have to do it again once, but the part you want to follow the steps, is symptom: LEDs flow, the fan noise is heard, but the display is black or white.

  Please let me know the results of the troubleshooting steps.

  Looking forward to working with you!

• Pavilion dv7 will not start

  Hello

  so, my HP Pavilion dv7 laptop computer 1003eo won't start. When I turn on it, all the light light up and I hear the usual fan noise but the screen remains black.

  I removed the charger and the battery and press the power one button couple of times (and held it for about 30 seconds). Unfortunately, which did not help.

  I also tried replacing the RAM modules, but I am always greeted by the same black screen.

  Is there anything else that I could do or should I just accept the fact that the phone is dead?

  I think that you blew your laptop Cpu or Gpu.

  Because there is no screen.

  You can try to remove the battery and press the power button 10 times.

  Then leave it for an hour.

  Have you still warranty?

  Drunks.

• dv7 work, but the screen is blank

  I had my dv7-4180us for a month.

  The screen just deleted one day... the backlight of the lcd screen is turned on, and when I connect to an external monitor it show that the laptop itself works very well.

  When booting the laptop, the screen flickers when the hp logo comes on with the 'Starting Windows' screen (it flashes briefly and remains off even when you press F8 to access the BIOS screen). A cursor then comes to the screen (with the circle "busy" thing), for approximately 2 seconds, during which the display IS stable. Then that's it. You hear the sound when the logon screen is supposed to appear, and also when Windows actually loads. Occasionally, it sparkles, but the screen remains blank with the LCD backlight on. Fan comes on intermittently, as usual, all lights are functioning normally.

  Once she nomalised by itself for about 2 days, then deleted again. Windows restore did not work. The only support of HP said something had to perform a recovery, as it could be a windows problem. But it won't have the same BIOS display!

  Help!

  Hi again sent to the laptop to hp. came back, with the display now works correctly.
  On the worksheet they have ticked 'View' and 'Cable '. So, it is obviously a cable problem.

  Thank you all.

• Computer HP Pavilion DV5000 laptop will not turn on or off

  This laptop is used every day and worked perfectly until this morning.

  I have attached the power cable and it works, but the screen remains blank. All lights normal power along the upper part of the keyboard are light, but that's all. The blue light along the front flashes.

  When I try to turn off the power by pressing the power button, nothing happens. The lighting and the computer does not turn off.

  Oddly, when I unplug the power cord, fires off - but only then.

  I tried to boot from the DVD drive without result.

  Any help would be very appreciated to get my laptop running and upward.

  In the absence of any other advice or suggestions, I decided to try to clear the CMOS memory. In the process, I discovered that the RTC battery was bad, so I replaced it with a battery in good condition and Hey Presto! -l' computer is now back up and functioning normally. Happy days!

• Screen remains black, while all buttons are light

  original title: serious problem with my computer!

  I'm trying to fix my computer because something is obviously wrong with it and I'm not very good with computers, so I don't really know what I'm doing, and I think I might have messed up even more now.

  Recently, I tried to back up my files on my d drive but he said he couldn't because my c drive was damaged so he told me I could fix it and I tried, but he says he couldn't when it is in use and told me to program it so that he could check it out when I start then my computer. Then I restarted my computer, and every time I restart my computer, it has a problem back on. The screen remains black then that all the keys are lit and then after a minute or two, it hangs, and then she did it again and again until I have press and hold the power button to turn it off. I have to finish by wait 5 minutes before turning on so it lights correctly, otherwise it will just do that again.

  Then he started toward the top of normal, of course I know what the disk check thing looks like now because what happens now, but before it has not then I thought it did not work and as a last resort, I wanted to wipe my hard drive clean because I tried everything I could, and I don't have the money to fix right now and probably won't for a while. So I followed all the instructions for the recovery of the system and none of the other stuff worked and I decided to go with my disk wiping hard completely clean and restore factory settings. I followed all the instructions and then it turns off my computer, trying to wake it up, so his restart of course, but he does what its been recently when it restarts and crashes.

  If I turn it off and wait a few minutes, then turn it on and I was really upset at that time here because I thought that it did not work. Its starts upward and there appears the disk check thing and it says system files verification on c: responding file type is NTFS. __Cannot volume open for access.__windows live has finished check the disc. then goes to the login screen I open a session, but then the screen is black and the only thing I see is my mouse. It was like it maybe 30 minutes or more, and I didn't know what was happening so I turned off and then tried to turn it on and it does the same thing next time. I thought that maybe when he crashed he screwed up the process, or perhaps checking file system on c drive messed up. So when I had the chance, he finally started upward and I connected again but this time on the user prompted and everything was still there but it was EXTREMELY slow, as it took maybe 10 minutes or more to open what anyone and it loaded really slow when I logged in. I finally made the thing about system recovery again after a few hours of waiting so he can keep loading, cause whenever I clicked it, it does not always work. And then it's the same thing all over again. He obviously never erased from my hard drive, so I probably * my computer even more, and then it was already * upward and it was a gift, so I would really like to fix so if someone can help me maybe I would really appreciate it!

  Hi TeresaBilski,

  ·         How have you tried to reinstall the operating system?

  I suggest you erase the hard drive and do a clean reinstall of Vista. I would like to ask if you still have the boot floppies for Windows Vista that came with the computer. If this isn't the case, you will need to get a.

• the screen is black and all the lights are on do - what I do?

  When I turn it on all the lights turn on but the screen is black

  Hello

  Before you attempt this procedure, the judgment of the laptop, remove the AC adapter and then hold the power button for 20 seconds to dispel any residual charge in the motherboard - do this whenever you stop before changing/deleting modules.

  Try to remove one of the memory modules and see if the computer will start.  If it is not, move the same module to another location and try again.  If it still does not start, remove the memory module and repeat with the other to see if any combination will allow the laptop to start.

  A video and a description of how to remove the memory modules is on the link below.

  Power light is on, but the screen is black. Other lights are not on.  How will I know if I need to do a hard reset, replace the motherboard or buy a new laptop.

  Hello

  First, try a hard reset:

  Remove the battery and unplug the DC power adapter.
  Press and hold the power button for more than 15 seconds.
  Plug the DC power adapter (leave the battery for now)
  Press the power button

  View your results.

  If no joy, repeat the hard reset in a dark room and have a flashlight handy. Shine the flashlight on the LCD screen. If you see a very Dim normal Windows login screen so the display inverter is probably not and must be replaced.

  Is your laptop still under warranty? Check the label of arcoded on the bottom of the laptop.

  Best regards
