  Hello:

  Yes, you can do it.

  Is it a matter of having a lighter weight?

  You can also run the power cord with the battery installed.

  Sometimes the battery is so bad that you have to remove and the laptop will not work with the battery removed and plugged power cord.

• Envy laptop: my notebook of envy not turn off when I stopped in Windows 10?

  Hi all

  I tried everything to get my HP laptop work properly.  I am a computer programmer and my laptop not stop using the power HP power and sleep, using Windows 10.  I have to update the display driver, I tried different settings in the HP power settings and still no luck.  I have never seen anything like this before.  All my drivers are updated etc.  I'm about to give this thing!  When I select my phone stop Windows 10, should close and doesn't have the power button / light on.  When I try to go back on my laptop, it is dead and I hold the power button for about a minute before it turns off so I can restart the laptop?

  Hi Mark,

  You've already tried this, but if not, it's definitely worth it.

  On some machines, the pilot for 11 series IMEI has been known to cause that kind of question of the judgment, so it may be worth trying an earlier version.

  You can use the following method to install an earlier version of the driver IMEI.

  Download driver IMEI on the link below and save it in your downloads folder.

  http://ftp.HP.com/pub/SoftPaq/sp66001-66500/sp66228.exe

  Disable your wireless card (should be f12 ).

  Open your download folder and run the installer - it warns you that it is an earlier version, but simply continue.

  When finished, restart the laptop.

  If the computer shuts down correctly, turn on your wireless adapter and use the utility on the following link to prevent Windows 10 to update automatically the driver IMEI again.

• Compaq Presario CQ62-209WM turns is not on

  I have a Compaq Presario CQ62-209WM.

  I recently had a problem with this computer where the screen would go completely black during start-up or process during recovery from sleep mode.

  I updated the Bios and the problem disappeared, but now there's another problem.

  Because the Bios has been updated, the computer turns on if the power cable is plugged. But if I turn it on and then unplug the cable, it works very well. It does not lose power and the battery holds its charge normally.

  No idea what could be causing this?

  Try this it should help

You don't need an inverter of the screen you can see where it is at page 62 and page 20, step 13 in the removal of the display Assembly procedure will show you how to replace. The part number for the inverter are on page 27.

• Compaq presario cq42 screen becomes black when the external monitor is unplugged

  Compaq presario cq42-137tu running windows 7 32 bit.

  I've been using a connected external display on the vga port and now every time I disconnect the monitor and restart the laptop the laptop LCD screen will display the original message of compaq and the black windows boot screen with the logo but then turns off. If I reconnect the extrnal monitor it will work fine (even if the external monitor is turned off)

  The screen of the laptop works fine without the external monitor connected in safe mode.

  I used both the HP support and the setting in the display panel to select single monitor and set the display on the screen of the laptop, but every time that the external monitor is not connected the screen turns off. The external screen does not need to be turned on, just to connect to the laptop monitor work. I also tried to download the graphics driver and put it back.

  If your laptop is a ComPaq base model then there is the (built-in) Intel UMA / GMA 4500 M - GL40 chipset with video memory sharing and you should consider downloading and installing the driver Intel graphics high definition (HD).

• HP Pavilion Notebook e101sp 17: best way to charge 10 Windows with the laptop HP software (post regularly update 8.1-> 10)

  My HP Pavilion 17 - e101sp Notebook PC (ENERGY STAR) came with preinstalled Windows 8.1. I later upgraded to Windows 10.

  Although I had Norton Internet Security installed since the bootups earlier, I still have some virus infections from time to time (discovered through runnin ClamAV from a Linux Debian partition, I put in place on the same computer) laptop. After the expiration of the 1 year subscription NIS (I had lost confidence in it right here...) I played around with a few other sollutions.

  In the end, I now have a Windows essentially not fixable (infected) 10. It's not scary for me because Linux is my main OS 'at home' for 15 years now. However, being the standard Windows "de facto" is it much, I still would like to have a copy of own work, installed.

  My question is, in the current scenario, as I mentioned, which of the two is the best way to have 10 Windows installed with all the goodies of HP, alongisde, my Debian Linux system? And what care I would create throughout the process?

  1 reinstall 8.1 can I leave HP recovery disks that I made at the beginning (and hope that does not erase the Linux partitions, I created afterwards - I need more than "hope" in fact, I need evidence-based knowledge on this one!). And then upgrade to Windows 10.

  2 install a Windows 10 fees (from DVD created from the .iso file downloaded from Microsoft), hoping that it activates properly with the key contained in the UEFI BIOS (I think that this 'hope' is pretty much made to knowledge database) and then get all the goodies of HP... by a simple download from the HP site?

  I think option 2 is the safest (and fastest also!) but I'd well informed comment before that I have try.

  Thanks in advance.

  Hello:

  Option 1 is the only way you will get to keep the programs provided HP with your PC, and they reformat the hard drive, so you will lose everything.

  Option 2 will put a clean install of W10 on your C:\Drive and you will be able to leave everything intact, unless you format the hard drive.

  If your current installation of W10 has been successfully activated, W10 will automatically activate once you install it again once you're connected to the internet.

  To install W10 in this way, you select the "I don't have a product key option,' when you get to when Windows asks for the prouduct key.

  The only software and you will be able to install the drivers which will be available on the page of the driver and support for your laptop.

• Stream HP Notebook PC 14 guard turn off?

  • My HP Stream Notebook PC 14 keeps turning off, as in the screen just goes black. I can try turn it on, sometimes it runs for a few seconds then turns off, other times, it works normally. But from here, I can't use it at all because it won't just turn. Strangely when it lights up, the cursor is usually not on the screen and appears only after a minute. It is fully charged and I have the charger plugged. It has enough memory, and I've seen problems of this kind where laptops overheated, but the HP Notebook PC 14 Stream has a solid state drive, and it feels never hot. Any help?

  I solved my problem. The problem was that the casing of the laptop near the area of the power button has become a little loose. Whenever I moved the laptop, he must have turned on the power button / stop and turned if off. I had a look on the underside of the laptop and found a screw under one of these stickers rubber in the corners. It turns out that he himself had loosened over time. I've screwed, the case is now tighter, and the problem stopped intervened.

• HP 14-r024tx Notebook PC: slow perfomarnce and crashes when you try to open Microsoft Publisher after restart/refresh

  Hello

  I just bought my HP laptop 2 months ago. Everything was fine, quick and convenient until the market a few days ago, it prompted a message saying that I need to update it. So I did, and thereafter, all my installed applications like Skype, internet browsers, etc., have disappeared. I tried to reinstall applications and all goes well but a bit slower. I thought that I needed to update some applications to improve performance, so I checked for some and tried to install the.

  Then yesterday, when I tried to open Microsoft Publisher, my laptop suddenly froze. The mouse and the keyboard didn't work so I had to turn off using the power switch. And every time I turned it on, everything was just slow.

  Can you help me solve the problem? Also, can you help me to speed up its performance?

  Thank you very much in advance.

  Hi @blissss ,

  Thank you for visiting the Forums HP's Support and welcome. I will do my best to help you. I read on your 14 HP - laptop r024tx with slow speeds. Thank you for all the information on what is happening.

  Something is slowing down the laptop. Have you installed some antivirus or firewall? If you disable what are your speed better. I got a DVD in my notebook that has slowed the process of starting a lot. You can check this.

  Here's a document on improving your system.

  Make sure that all updates are completed within the control panel or click the Windows key and start typing the laptop settings, then go to update.

  Please let me know how it goes.

  Thank you.
