Laptop not turning on after bios update

My laptop isn't turning on at all, not even screen. Started occuring after I installed some updates through hp support one of which was a bios update.
Please help.
Model: HP Pavilion DV6-7029tx
Windows 7

Try testing the Hard Drive.  http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00439024&cc=us&dlc=en&lc=en&product=3816360&tmp...
If this doesn't work take the Hard Drive out.

Then test it again.  http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00439024&cc=us&dlc=en&lc=en&product=3816360&tmp...
Let me know if it allows you in the BIOS. 
If not it could be the Motherboard giving you the issue.
Also, try restoring the BIOS.

  • T440s will not turn on after BIOS update

    I have been using Windows 10 Pro 64bit for a month with only 1 persistent issue which was that the Intel Management Engine would give errors that it wouldn't shake hands with the firmware. The event error stated it was related to MEIx64. I've tried several different drivers, and different versions of Intel Management Engine but still had the same issue. So I decided to update my bios as I was on the 2.17 version. I followed the instructions step-by-step including deregistering from AMT or something in the bios. Once I ran the update utlitiy as admin within Windows it began the update and then the laptop completely shut down. So I left it for a little bit thinking it was doing something. It never turned on and now it still won't turn on.  The screen will stay black, no backlight at all of any kind. The power LED on the power button turns on (and the keyboard lights) for about 3 seconds then it turns off and makes a quiet pop sound. It then turns on automatically but with the same issue of no LCD screen, no backlight, then after about 20-30 seconds it turns off making the pop sound again.  Also, when I plug the AC power in, the power LED blinks 3 times. Not sure if this is normal or not. I've tried removing battery and AC, pressing power button 10 times at 1 second intervals and then holding power button for 30 seconds to no avail. I've tried the emergency reset button on the bottom of the laptop. I've unplugged the CMOS battery for about 30 seconds and tried again, all to no avail. I've also tried putting a bootable CD in my external CD drive to no avail. I do have an active warranty (3EZ - depot) until 2017. Is there ANYTHING else I can do to get this thing fixed???? PS - It appears to have an internal backup battery which I have not taken out. I'm trying to avoid having to really open this thing up and start removing stuff. Thanks

    Haven't gotten a reply at all so I filled out a service request and Lenovo shipped a box to put my laptop in and it ships today next day air. Thank goodness for warranties.

  • Vaio Flip does not turn on after BIOS update

    Hello Community, I'm using Sony Vaio Flip 13'' (SVF13N13CXB) for about a year.Yesterday I decided to upgrade my firmware to address noisy fan etc. So I got update utility from Sony website, launched it, got prompt to reboot my PC to continue upgrading process. After rebooting I got a Vaio logo and progress indicator rolling. After reching 66% it stuck. I waited for about an hour, there was no progress, so I had to power off my PC (hold power button for 5 seconds).Now when I try to power it on using Power or Assistance buttons, it will turn on the green led, fan starts making some noise, and thats it. Screen is blank. I searched throught this site, tried to press battery button at the bottom with clip, discunnecting/connecting power adater, etc, etc. Unfortunatelly nothing helps.I assume the BIOS is now corrupted (I may be wrong although). Please can you suggest how can I recover the firmware to factory state? Thank you, Vitalii

    Hi vetooon,
    Welcome to Sony Community!
    It looks like your laptop is already corrupted. Please follow the steps below to troubleshoot your computer.
    Power Cycle the computer by poking the battery reset hole [4] for about 15-20 mins with the laptop unplug. 
    2. Plug it back in then press the power button. If issue persist proceed to the next step .
    3. Press and hold the power button for 3-5 mins or until its completely off. 
    4. Press the "ASSIST" button. When you see the "Vaio care Rescue mode" page, select F2 to go to BIOS then reset it to default. 
    5. Go back to "Vaio care Rescue mode" page, we'll check if you have a Restore Point so we can go back to an earlier date. On step #7 instead of choosing the "Recovery and Maintain" choose the Advance Option, then choose the current operating system of your pc (ex. Windows 8) 
    6. If issue still persist then click on this link and follow the instructions carefully. Please take note that on this process you will go back to factory setting and all the files will be deleted. You can seek the assistance of a professional technician to retrieve your files.
    I hope this helps you.

    Jen

  • PLEASE HELP!! MY Toshiba L300 Laptop has black screen after Bios update

    Hi, I was looking on Toshiba's website last night for an updated driver/software to fix my windows update which was not working. Whilst looking I had a message pop up saying Bois out of date and there was an updated verion, so I clicked update for my specific laptop, thinking that will be better. A window come up saying do not switch off. The the screen froze, and I could not do anything whilst it slowly updated, then the screen went black and remained that way for a considerable amount of time. I tried rebooting the laptop, it turns on, but bios will not load, the screen just remains black. Can anyone please help me, why would an update be on Toshiba's offical website if it does this?
    Laptop: Toshiba L300-25G
    Model: PSLB8E-0PG007EN

    That doesn't appear to be a US model, and this is the forums for Toshiba USA. You may want to contact Toshiba in your region. If it's a European model, you could check the Toshiba Europe forums.

  • Satellite A series does not start up after BIOS update

    After bios update with downloaded utility my notebook does not start up.
    Did this case covered by warranty?

    Im not quite sure if this would be covered by warranty. You should contact the ASP in your country for details but I presume its not covered.
    PS: Did you try this workaround:
    - remove battery, disconnect the AC adaptor
    - wait ~ 40min
    - connect both devices again and try to power up the notebook

  • Laptop won't turn on after BIOS update

    A few days ago, my 9470m Ultrabook automatically updated its BIOS. This was fine, as it has updated its BIOS before in the past. I went to do some things while it updated, and when I came back, the laptop had turned off. The charge light (the lightning bolt light on the edge of the laptop) was blinking white and amber and did not turn on when I pressed the power button. When I took off the battery, the light stopped blinking, and when I put the battery back in, the light began to blink again, but the laptop still would not turn back on when I pressed the power button. I've tried taking off the battery and plugging in the AC only, but still the light would just blink and the laptop would not turn on when I pressed the power button. I do not know what is wrong. The laptop had been working flawlessly until the BIOS update. Any help would be appreciated.
    Thanks to any support.

    Hi,
    At first, please try a Hard Reset as follows.
    Performing a hard reset
    Disconnect all peripheral devices and remove all USB devices and SD media cards.
    Disconnect the AC power adapter, remove the battery and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
    Reconnect the AC power adapter (but do not insert the battery), press the Power button, look for glowing Light Emitting Diodes (LEDs) near the caps lock and num lock keys, and listen for sounds of a fan or other moving parts turning.
    If the computer starts normally after performing a hard reset, you are done troubleshooting.
    When the Notebook restarts keep tapping the f10 key to enter the bios menu.  Press f5 to load the defaults (this is sometimes f9, but the menu at the bottom will show the correct key), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
    I am waiting to hear back from you.

  • Laptop won't boot after BIOS Update

    My laptop took an automatic BIOS update
    Now when I try to turn on my computer it won't turn on:
    Screen is black
    Power button and f12 button lights flash at 5 second intervals indefintiely
    At the same interval a fan or hard drive can be heard spinning for a split second then stopping
    I've tried the hard reset (Remove power and battery fo 5+ minutes, plug in power but no battery and turn on) but no affect.
    The Windows key + B key with the power button for 1 second had no affect either.
    I can't find any info with my exact problem (All other info seems to have blinking light codes while mine is just at a constant interval)
    Thanks!

    @B1-17 ,
    Thank you for posting back.  Now based on how you are explaining the response you are getting after doing what you have done so far the next step will be to try and get a response with removing some components and then see what kind or response you get.
    Here are the steps you want to follow.
    First remove your memory from you notebook.  Here is a link for the Maintenance Manual that will show you how to do this.
    (When Removing Or Adding Any Part To Your Notebook. Remove Battery and Power Cord.)
    1) Remove bother Memory Modules.  Put the power cord back in only.
    2) Start your notebook and see if a new flash code or beep code happens.
    3) If yes place only one memory module back in to your notebook and try rebooting.
    4) If you boot up then we have a bad stick of memory.
    5) If you still have a flash or beep code. Remove the single memory module and try the other.
    6) If this lets you boot up.  Replace memory module that is not in the notebook.
    7) If you still have the original problem or a new beep code.  Power down again.
    8) Now remove power cord then the hard drive.   Use Maintenance and Service Guide for instructions.
    9) Try booting up again and see if this changes the original flash code or beep code.
    10) If yes then replace hard drive if no then contact phone support for repair options.
    At this point if there is no change in the original flash or beep code you are looking at a repair.  For information on how to get your system repaired please contact our phone support.
    Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region. http://www8.hp.com/us/en/contact-hp/ww-phone-assis​t.html

  • A1000l-f will not turn on after firmware update

    i bought my tablet last night  as a black friday sale item from office depot and it was working fine for about 2 hours. it then said i needed to update my firmware so i did. after a minute or two a screen popped up stating it needed to shutdown or something and did i want to do this now or in 30/60/90 minutes. i picked for it to do it now. i went for a walk and ever since then the dang thing will not turn on, it will do nothing. no vibrations, no noises, nothing. the back sticker says it is an a1000L-F, but it is an 8gb so i am assuming it is not an actual F? any help? the battery was at 68% and plugged in/charging when i updated the firmware. i also left it plugged in and charging all night (10 hours) and still does nothing.
    Solved!

    well, before taking it back to the store i tried plugging it into my iphone base charger/plug. turned right on! not sure why it died so fast when it was at "68%" while plugged in charging...but it did. i charged it to 100% and it has worked perfectly fine ever since. maybe the charger plug that comes with this thing sucks, i dont know....but it works now just fine.

  • HT4623 IPhone 5S will not turn on after newest update.  HELP!

    Hey all,
    I agreed to update my IPhone5s last evening and went to bed.  Now the phone is off and will not turn on.  Any suggestions?

    Try this:
    Plug your device into the original charger & block in a wall outlet and leave it alone for a couple of hours. Then, while it is still plugged in, try the reset again as described above.

  • Satellite M60 will not boot up after BIOS update through windows

    Hi all,
    I was updating my bios on my M60 with the latest bios version and I was following the windows flashing procedure (the recommended one) and it blue screened and dumped. Now the laptop wont boot, wont even post. Just a big dead brick :(
    I'm fairly proficient with hardware (I'm a software engineer) but I do not know how to reflash a laptop when this sort of thing happens. Is there a trigger bios reset on board? Is there anything I can do my self? If I take it back to my dealer how likely is it they will be able to reflash the bios in house? (Its a fairly large dealer in the Toronto area)
    This being a work system I need the solution that has the smallest time impact - cost is not too big an issue.
    Any help would be grand,
    thanks in advance.

    Hello Kristan
    According to your problem description I presume the BIOS chip is damaged and unfortunately you can not do much alone. Please contact Toshiba service and explain them the situation. They will explain you everything you must know and you can talk with them about costs and the time they need for notebook repairing.
    Bye

  • SWR50 It does not turn on after the update

    Greetings
    After the last update with PC, when trying to turn on the device, showing boot-animation, but without success. I left on for a long time.
    Repeat the update, at the moment, it is not possible ("update is not required").
    Before this device is working properly, and updated via the PC correctly.
    Earlier and now to update device used Sony PC Companion 2.1.
    Thank you for your attention.

    What if you connect the SW3 to a wall charger > press and hold power for 15 seconds > let it charge for an hour. or use PCC or Bridge to repair it.
