Hi @Vishalwagh123,

Welcome to HP's Forums a great way to get help. It's a great place to find answers and advice! Thanks for the post.

I understand you have questions turn on/off the device and you must press the power button several times for him to start. I'll be happy to help you.

Please try these steps first. Perform a hard reset.

  • Steps to do:
  • Turn off the computer and unplug the charger. Then remove the battery.
  • Press and hold the power button on the unit for 15 seconds to carry out the static electrical charges inside the machine.
  • Replace the battery and the charger plug it back. Try to turn on the computer.

If it fires up immediately the issue is resolved. Otherwise, try to turn on the computer without the battery and check that it works immediately.

In your message, you said that it works very well with the charger. However, I need more clarity here to help you better.

It works immediately when the adapter is connected and the power button is pushed only once?

If you again press the power button several times, it may be a faulty power button, and you will need to contact the hotline at the service of the unit.

Let me know what happens when you try to turn on the unit without the charger?

Hope the problem is solved without hassle. Please keep me in the loop.

Take care and have a week Holy.

  • Help - HP Pavilion a6030.uk desktop computer. Have to press the power button several times to start?

    Hello

    I have a HP desktop computer. The model is HP Pavilion a6030.uk, Opertating system: windows vista.

    My computer has had no problems at all until yesterday for some reason, I had to push the switch several times to start until he finally turned and did normal starts. As I would press the power as normal to start button, but all of a sudden, it turns off after about 2 seconds and so I would tap on the switch several times and each time it will not start and turn off, then the power button could be pressed again until it would finally turn on and start and run as normal and seems to work correctly. And it was the same thing today, I pressed the power button mutiple times (for example 6 times) until she finally started as usual.

    Savvy/computer im not very well informed or wise in this area, please someone will help me and give me some advice/help to fix/resolve this problem.

    Thank you for taking the time to read this and any help would be appreciated for this problem.

    Vonbon90, welcome to the forum.

    When I see these symptoms on an old computer, I think it may be a power supply (PSU) failure/ing.  Here's a guide that will help your troubleshooting it.

    In addition, you could test the memory.  This can be done by removing all modules of memory and replacing them one at the time and start.

  • Something changed recently - now, I have to press the "arrow" to go to a Web site in the address bar. Is there a setting that I can change?

    Very recently, my Firefox has changed. I used to be able to start typing, say, 'www.google.com' in my location toolbar window. This would provide a drop-down list of recent sites, and I just click the line "www.google.com". Firefox would immediately take me to this Web site with a single click.

    But now if I click on the line 'www.google.com', it simply puts "www.google.com" in the location toolbar window, do not send me to google. I have to press the arrow to the right of the address bar to go to the page of google.

    Thus, something changed last week - maybe a setting has updated? I looked at the options page and can't seem to find something that applies.

  • When my computer goes into sleep mode, I have to press the power button to turn it back on.

    original title: sleep/hibernation

    When my computer goes into sleep mode, I have to press the power button to turn it back on.  I used only having to press a key on the keyboard.

    Can someone tell me how to solve this problem, as if it was before?

    Well, on the theory that your computer is awkward, try to change the settings to another thing and OK your way out the control panel.  Then go back and put them in the way they were and OK your way out.  Occasionally, it will reset the internal parameters and things can return to normal.

  • P1102 - why I have to press the power button before printing

    Hello

    I was wondering if anyone else knows how to avoid this problem. We have a P1102 connected via USB on Win 7 64 bit.

    Is there a setting somewhere that allows us to not have to press the power button on the printer before printing. It is now connected to the pc. The pc is turned off at night.

    It is very annoying to have to push the button before printing. This may sound trivial, but our old Hp laserjet 1100, only has been replaced with this P1102 as the new pc have no place for a parallel port card, and you never had to press the power button before printing with that, this feels like a step and is very disappointing.

    Thanks in advance.

    It seems that the printer software is not save the auto power off feature is set to never.  I would definitely try update the internal firmware of the printer to see if updating automatic stop is set to never work.

    Click here to access the download page for the Laserjet Firmwares.  Select the P1100 series in the drop-down list.

    This should be done so that a USB cable to connect the printer and the PC.  I would like to know if the firmware is able to get the printer to stay alive.

  • Lenovo Y40: Must only press the power button two times to turn on

    Hello

    A few months ago, I bought my Lenovo Y40 on the Lenovo Web site and recently, to turn on, I have to press the power button twice. When I press that once, the Lenovo logo is displayed on the screen, but after 2 seconds it turns off. On the second attempt, finally the laptop turns on and the windows is started.

    In addition, rarely the phone stucks on the lenovo logo screen, is necessary to contain the power to reset.

    Someone had some problems like these describe above?

    Thank you.
    Pedro Lopes.

    Hello

    I contacted Lenovo's Support and they recommended to perform a full recovery of the system. Apparently, it worked because I did not suffer these problems since I got windows. Probably, there was a problem with the partition that has been responsible for the initialization of the system.

    Thank you, Pedro h. Lopes.

  • What happened to the button on the address bar which allow you to see the pages you had been so that you don't have to click the back button several times? I use it all the time and it is not on FF4.

    What happened to the button on the left end of the address bar which allow you to see the pages you had been so that you don't have to click the back button several times? You can look at the drop down window of pages and just choose whatever you want. I use it all the time and it is not on FF4. I want to go back to the old FF.

    If you right click on your back button, or click and hold down the mouse button, it will display the list. (I prefer a click-right, because sometimes my fingers slide when I try to click and hold)

  • What will happen with my agent and active Windows 8, I will have bought with the laptop after I swap HDD with SSD?

    Original title: replacement disk and windows.

    Hello guys.

    I am considering buying a new laptop. The model that I found and I like has a HARD drive if I want to replace it with the SSD to the format of my previous laptop. (Due to the low energy consumption, greater speed, etc.). So I have a 256 gb SSD in my previous loan of laptop replace new one HARD disk, yet what will happen with my agent and active Windows 8, I will have bought with the laptop?

    I can reinstall windows 8 on the SSD, but I don't have a key to activate their... How will I be able to get the key from previous series if the laptops will only work with a recovery partition these days here? I asked a guy in the store, I buy my laptop since and he told me that he does not know and I have to ask for help. However, to create a message of support I need a serial number of the model I did not because I have not yet bought a laptop, so I don't know what to do... I really don't want to stick with the HARD drive, but also I can't afford another model.

    Is it possible to do a recovery with my laptop disk when I get it, then replace the drive with my SSD and run the recovery disc I made?

    The laptop I want to buy is an Asus if that helps...

    Thanks in advance...

    The 'Raw' State is not necessary, it is the State of any drive (SSD drive or hard drive) would be in if you just remove a disk new in box and will need to be "initialized", since you have already used the player already initialized sound.

    Do not format the drive, rather than delete all existing partitions, (the SSD shows then as being "unallocated"). Now you are ready to restore the backup Image you created. During the restore process Acronis will recreate the partitions that were on the hard drive on your SSD.

  • An error message appears every time I start my laptop Alienware of window 7, the message reads: "wscript.exe - no disk".

    Hi all

    An error message appears every time I start my laptop Alienware of window 7, the message reads: "wscript.exe - no disk" there is no disk in the drive. Please insert a disk into \Device\harddisk1\DR1.

    I'm a bit confused with this error message, I don't know if there are viruses in my computer, or the reason why this error message whenever I start my computer,

    Although I installed file encryption software.

    This could be a virus? and how to prevent this error message appear on my computer.

    Sounds like malware. Run msconfig.exe, and then selectively uncheck items under the Startup tab until you find the culprit.

  • Increase in Wake - should not have to press the Home button to unlock

    Hi all

    I appreciate the work that the Apple development team did to iOS 10. Most of it's amazing as usual! BUT...

    The revival of the Wake feature needs an additional configuration option. In fact, some of us LIKE how quickly iOS 9 unlocks the phone and have the habit of hitting the power button to turn the screen to access the shortcut of the camera or using a finger not configured to press the Home button.

    That said, if I 'raises to Wake"my iPhone, having to press the Home button to complete the unlocking process is not intuitive. It must simply unlock and go to my home screen.

    As this MUST have been done intentionally, I think that you should give us the option attached to "Raise to Wake" function to enable or disable the duty press the Home button to unlock.

    Who else agrees? Thanks for your time!

  • YouTube I have to press the button "back" twice to return to the previous page

    Hello!

    FF constantly and across operating systems (I use many for most Linux distributions) fails to simply go back to the previous page when I press the button 'back' of the browser. He did it for months. Completely reset FF does not work, or not to empty the cache then restarting it manually.

    It is a very irritating problem, especially since I prefer FF so strongly on another browser and do not want to hit back twice whenever I want to go to a play list/etc. To clarify, it reloads the page/video, I am currently on, then finally doing what I want to after 2 clicks the 'back' button For someone who needs YouTube to work, as well as for reasons a many great tutorials that needs resolution as soon as POSSIBLE.

    Thanks in advance for any help! In my opinion, I've isolated probably the question enough that it is very likely to be a problem with my OS or malicious software.

    What is the most likely culprit here?

    I should also mention that this is happening not only across operating systems, but also on a laptop Lenovo G770 and an AMD FX - 8350 16 GB RAM PC desktop I built very recently.

    If it works in Mode safe mode and normal mode with all extensions (Firefox/tools > Modules > Extensions) off and then try to find which extension is the cause by allowing an extension at a time until the problem reappears.

    Close and restart Firefox after each change via "Firefox > Exit ' (Windows: Firefox/file > quit;) Mac: Firefox > quit Firefox. Linux: Firefox/file > exit)
