Laptop does not start after HP Support Assistant ran some update

ENVY of HP dv7-7387er

Yesterday my HP Support Assistant showed a message that there are a few critical updates. I confirmed to download and install it. After it was something like the BIOS update. And now my computer will not boot (black screen, no sound, only power led is on). I have to postpone my trip to fix. Can help you with something?

I tried http://support.hp.com/us-en/document/c01443371 , but it did not help.

Has been useful for me this: remove the battery, wait 1 hour, insert the battery, turn on the laptop and everything works ok. The key was - remove the battery for a long time.

    I therefore decided to remove a processor heat sink and empty dust. It was released with processor...
    There was a huge load of dust, so I cleaned it, put new thermal paste...

    Now computer laptop does not start loading Windows.
    It checks only the CD, HARD disk, and that's it.
    Screen is blank, ON the indicator led is on.
    Two fans periodically start to turn (when they stop radiator heat - so the processor works)

    Where is the problem?

    Thank you

    Hi Dubas,
    You can access the BIOS when you try to start your laptop? This can give you a clue as to why the OS will not charge.

  • Laptop does not start after installing vista sp2

    My Dell XPS 1530 stopped working after installing vista sp2. He gave me instructions for installation, step 1 of 3 and it went all that they way up to step 3 of 3 and said its closure and never came back...
    Please let me know, how to start the laptop.

    Hello GoogleGuru,
    Thank you for visiting the Microsoft Answers forum.
    Because your computer does not start until the desktop computer, we were able to try the system restore to a point before you install SP2.
    Thus, with the computer is shut down. Press the power button, then press on and press F8 until you see the startup options, and then it will give you the ability to boot to the last known good configuration. (select it).

    If this does not work, you can try to boot from the Vista DVD and use the recovery console to perform a restore of the system to another point in time.

    Post back with the results.

    Thank you

  • [Solved] pc with xp home edition as the operating system does not start after installation of SP2 via automatic updates

    Hello everyone. After formatting my hard drive I reinstalled windows xp edition sp1 family and then installed the latest version of windows update agent. I have the auto update set to download the updates automatically and notify me when they are ready to be installed. Initially, he found 3 updates that I installed and rebooted. He concluded 58 updates. Again, I've installed and restarted. After that, we found ServicePack 2, I installed as well. But after the reboot, the pc does not start. What I get is the windows xp logo which discoloures after a few seconds and I don't see a bar moving from left to right. I left it like that for 3 hours, but nothing has changed. Also, it does not start in safe mode. I get a screen with red and green vertical lines in this case. Anyone know what's the problem? I'd appreciate any help. Thank you.

    I was finally able to solve this problem. That's what I did. I reinstalled windows xp home and followed the same path (but his definition of the automatic updates notify me before downloading or installing updates) until the automatic updates found in the new service pack 2. This time that I did not choose to download it. Instead I downloaded from here http://www.microsoft.com/en-us/download/details.aspx?id=28 and then started in safe mode and installed. I don't know one that makes the difference but service pack 2 has been successfully installed this time and tha pc was able to start after installation. Before that, I also downloaded and installed the latest versions of 2 drivers through drivermax. I mention this in the case where he has also made a difference. After the service pack 2 installation and restart, automatic updates will be found a few others brought up-to-date, but after installation and reboot, it found no others. I had to visit update windows Internet explore and search for updates it and managed to find other updates and finally SP3.

  • Acer laptop does not start after the blue screen

    After I got a blue screen (flashed by too fast to see the error message) when I try to reboot my acer 5610Z laptop computer with vista home edition, usually nothing happens at all. sometimes windows is trying to run the Startup Repair tool, then crashes and only a cursor flashing at a black screen.  Tried to open the case and clean the Fan & Heatsink heat to air without effect.

    The blue screen came a few days after I started using a new USB mouse, but the fan seemed to get high a few days earlier.

    But I noticed it will make the road to startup repair only if the battery is in, and never if only the power cord is attached.  Also, if I let the computer sit for several days, it is more likely start (even though he never passed from the Startup Repair).

    1. try the system restore.

    2. try to do a startup repair disk.

    3 acer Recovery Options.

    4. contact Acer.

    Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

    Try a restore of the system once, to choose a Restore Point prior to your problem...

    Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

    See you soon.

    If the above does not work, try to make a Bootable ERD to do a Startup Repair:

    As is the case with most computers/laptops these days, they do not come with good Vista disc to repair only the recovery disks.

    As your grave in the category above, download the ISO on the link provided and make a bootdisk of it.

    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.

    You can make a tool to restart system, System Restore, etc. with it.

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

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

  • Laptop does not start after spilled liquid

    I spilled liquid everywhere in my laptop yesterday. And now it does not work!
    The thing is, I could activate it yesterday after I poured the liquid, it seemed ok.

    So I just turned off and left to dry.
    But it is not today.

    What should I do?

    Hello

    This is a really bad story and I put t see any chance of getting the laptop works without any replacement hardware.

    I think we are ve got the worst case. This means you have a short circuit that could damage the whole motherboard. :(

    I think you should certainly contact the notebook computer technician for a control.

    But it sounds really bad, Buddy :(

    However, good luck

  • Laptop does not start after Windows update

    I have HP laptop with Windows 8.1.

    It no longer starts after you install updates.

    It has happened before several times. I used system restore and it should correct the problem temporarily until the next time for the installation of updates.

    Now I can not even run system restore. He says that I have an administrator account.

    Help, please.

    The process I'll tell you will solve the problem, but it leaves a few effects. All the installed update will be uninstalled the version they had when you have installed 8.1 windows and programs in your programs (x 86) NO program file in the C: drive or the drive where windows is installed must be UNINSTALLED. The uninstalled programs will appear on your desktop as Applications.HTML removed. If you have any problem with the effects that I mentioned that process as follows:

    1. at start up press F11 to enter recovery.

    2. go on recovery to solve problems.

    3. then in troubleshooting, click on refresh your PC.

    4. wait it ends (it takes about an hour)

    5. your system is restored.

    Hope this helps

  • Laptop does not start after upgrading CPU

    Hello

    I have a dv2528ea and I decided to upgrade the processor and the RAM. According to the manual of the T8300 is compatible, so I bought one on eBay (so-called new). When I powered the laptop, the bios screen appeared as usual, but nothing more happens. Among the options available in this screen only works the "ESC" (boot messages I think). I can't access the configuration. The CPU, RAM, HARD drive and DVD drive is correctly detected, the BIOS and video BIOS are "shaded" don't know what it means.

    I know that I didn't break something because after putting the T7100 back in place, the computer worked fine.

    So my question is: is the burned T8300? Do I have a bios problem?

    I've never updated my bios (since 2007) and the CPU is not physically damaged, but this last part can doesn't mean anything...

    Thanks in advance, Pedro.

    Hi, Pedro.

    I hope it will do the trick.  F.0Une is old and I think that's the reason why your processor does not work.

    The problem is that you are under Windows 7.

    You can put Vista on it and flash, or do you know how to make a flash out of the file based BACK?

    I don't know how.

    I'm saying that you are taking a considerable risk if you flash in Windows 7.

  • laptop does not start after you install a new hard drive

    HP G60-630us laptop... .replaced hard drive... .installed 3 boot disks... After you remove the last drive, when you click on continue it is supposed to start... .it reads no boot device... . If put you the first disc to start, you end up back where you started... I changed the boot order and put the hard drive first... even starts

    Hello

    That sound great for the hard drive.

    With regard to the problem you have with Windows activation, it's because your laptop is listed as originally came with Windows 7 Home Premium - as I mentioned in my guide for the creation of a sale installation disc at retail, the image that you use needs to be also be Home Premium - IE you cannot move to professional or ultimate edition as the key on your COA label will not work for a different version of Home Premium and there is no way around that.

    The image that should be used is on the following link.

    Windows 7 Home Premium 64-bit.

    You will need to create another disc of installation using the above Image and then use it to reinstall Windows 7 - the activation methods I described previously, then will work fine.

    Kind regards

  • 4540 proBook s does not start after stopping

    Brand new Probook s 4540, B7A48EA #BED, of the box. Memory 4 GB DDR3, 500 GB, processor i3, SUSE Linux disk.

    I have install the battery, connect the power supply and turn on laptop. Linux installation started, got the message 'creating recovery root tarball' and wait, wait and wait with the same message of Linux. I rebooted the laptop and after that got Linux message 'Cannot find size info part of recovery' and restarted itself, every 120 seconds.

    I turned it off, by pressing the power button / stop 5 sec.

    After that, I can't turn on laptop. When I press the power button / stop, power, drive, browser and Flash of LED wireless, you can hear disc trying to turn but fail and all the lights go out and about 2 seconds later all lights flash once again, drive tries to spin but fail again and laptop does not start.

    I have 'power reset', updated the BIOS (F.40), removed the drive and DVD drives, tried without battery but no change in behavior. I returned the drive and the original DVD. After removing the memory, portable lights, as if, and caps lock flashing of LED 3 times which means error memory. After that, I did a "reset power" once again, reinstall memory and try to start the laptop. After pressing the power button / stop at the beginning I had same symptoms I described, and after 2 portable seconds began. I installed Windows 7 Pro. Laptop computer can be restarted Windows, but after stopping, he can't press start button to start / stop.

    One way to start is to move the memory in the other slot, but it cannot start after his stop. After his return in the first memory location can be started again until the next stop. And when start, does not start from the beginning, but after 2 seconds, for his second try. The BIOS memory test, the EFI system diagnostic and memtest86 has errors. I tried with different memory module but got the same symptoms.
