• power cord and power cuts

  Hello.  I have a Pavilion dv7-3171nr, Windows 7.  It's a laptop.  In the last few days, I noticed some strange things that I've finally pinned down for my power cord.  I've been hear a sound like a bug zapper.  Not as loud, very weak, that's why it took me so long to locate where the devil noise came from.  When I hear the noise, it caused small power outages in the lamp which is located in the room in which I work.  Then, of course, at first I think it is the lamp, or the light bulb, our electric system... Anyway yesterday I finally put the finger on it at the exit of that my power cord is plugged.  When I unplugged it, all of these symptoms have disappeared.  At that moment, I realized that it was plugged in all the other times also in all other rooms, I was in when all this was going on.  Everyone knows about this problem with a power cord?  I had a lot of laptops over the years and this is a first for me!

  Good decision.

• Pavilion m6 - stop suddenly and mystery of the power cord

  Hi people,

  I got a very strange problem with my laptop from m6-1035dx Pavilion the past two days. This is a reconditioned unit and have had some problems with it in the past (both hardware and software-related) that I managed to fix me, but this one left me speechless.

  It started yesterday when the computer was placed on a bed (with a CoolerMaster pad below, which I almost never separate the portable device) and immediately turn off the power. In the past, I had problems with heat stops, that I solved with a bit of air in canned and CoolerMaster pad said, so I don't think much. But the same thing happened today, and I noticed that when it has restarted, it does not recognize the fact that the computer is plugged in. Unplugged the cord/AC converter to three points (computer, converter, wall) and tried again, still nothing. Tried another outlet, blew the vents, power off and removed/re-inserted battery, still no recognition of the power. I reinstalled HP CoolSense (which I had removed several months before) and hope that would take care of things. Meanwhile, I shut the computer off again, and the LED power indicator lit on its own.

  Several hours later, the computer was reactivated and placed on a flat surface. Someone tripping over the cord, and the computer turns off again. The LED power indicator is out once more, so I unplugged the power cord and left for a few minutes. Blocked again, and the power was back.

  I am reasonably confident that I should replace the power cord at this point, but I want expert advice before I commit the money that him. It may also be interesting to note that while the power cord did not work, the battery (92%) had about two hours and six minutes of use remaining, which is well below the advertised battery capacity (to be noted that only Chrome was running at the time) and what I saw of the battery in the past. I think that the cable or converter can be shorted, then is it safe to use the computer at all? Wouldn't be a good idea to replace the battery as well? I will provide any other details if necessary and thank you in advance for any help or advice.

  Hi maestro35,

  Welcome to the HP Support Forums, I hope you enjoy your experience! To help you get the most out of the Forums of HP, I would like to draw your attention to the Guide of the Forums HP first time here? Learn how to publish and more.

  I understand that you are having feeding problems with your Pavilion m6. I'll be happy to help you with this. If it is running with the battery, I wouldn't worry about the replacement of the battery quite yet. As for the fact that it gives you less time announced that it could be the mere fact that the battery life decreases over time. You don't mention your operating system, this is why I have included two links below which will allow you to test and calibrate the battery. This will confirm that the battery is working properly.

  Test and calibrate the battery (Windows 7)

  Test and calibrate the battery (Windows 8)

  I agree that it appears as if the power cord is the question. If you have a similar cord, you might give it a try to see, but there's a chance it might be the prospects of power supply for laptop. If something is shorted, then you shouldn't really use the laptop but without testing actually physically we will not be able to determine if something is put in short circuit.

  Thank you

• Satellite Pro U400 freezes sometimes when the power cord is plugged

  Hello! I know that this problem has been addressed here and there, but I'd like to open a new thread about it. Here's the scenario.

  I recently bought a new Toshiba Satellite Pro U400-247 (PSU45E) with two batteries: (a) the original, (b) in addition purchased authentic of Toshiba PA3636U-1BRL, 7200 mAh. The laptop has the latest BIOS (4.80) and the latest drivers downloaded from Toshiba and installed (ConfigFree is not installed). I use XP Pro SP3 (own installation by myself). Everything works fine, except for one thing:

  Sometimes (but), when the laptop is running on battery power and I plug in the power cord, everything hangs and I have to restart. A few observations:

  It tends to occur more frequently when the low battery alarm has rung;
  (b) it seems to happen more frequently with the 7200 mAh battery and less frequently with the original battery.
  (c) it seems to happen most often when a USB device (mouse, for example) has been linked to the laptop, but it is not a rule;
  (d) it seems to happen less often when I move the mouse USB at the time wherever I am connect the power cord.
  (e) I've experimented a lot with Toshiba PowerSaver settings (for example to change the levels of CPU for my profile) but nothing I changed seems to change the situation.
  (f) I tried different suggestions I found on various forums, but nothing works (for example the BIOS settings);
  (g) otherwise, I can say that I have not really seen a smoother computer, everything works really fine, no other problem :)

  Everything that makes me think it must be some sort of bug in the drivers of motherboard driver PowerSaver or other drivers interact with battery, CPU or possibly USB. Y at - it an explanation to this problem and can it be rectified in some way (for example, by providing a driver update)?

  Hello

  First of all, I never heard a driver from the motherboard.
  There is a drive chipset or a graphics card driver. There is no such thing as a driver of the motherboard!

  Look, man. laptop should work fine even the AC adapter is connected or not connected
  If the laptop freezes while there might be a software problem, but in my opinion it could be hardware problem
  You must reinstall the operating system if the laptop would freeze always the issue might be related to hardware

  First of all the memory modules and AC adapter must be verified.
  If the problem persists even using new modules and AC adapter, motherboard may be affected.

• OfficeJet 8720: Officejet HP 8720 (D9L19A): power cord issue & legality in the United Kingdom

  Hello

  As a society, we standardize more than 150 sites on the new printer HP Officejet Pro 8720.

  We ordered about 8 at our dealer online recently (Softcat) and each arrived with a European power cord 2 pin and not a power cord 3 pins of the UK.

  This causes significant confusion for our end users, and I think that it is illegal to even provide goods in the EU without the correct national power cord.

  Our retailer say that HP have armed upward and shipped loads of these 8720's without the correct power cords. It seems that a mass surveillance on HP is illegal and a part too? How can this happen?

  Surely all stock the 8720's should be limited to the British market and fixed with the right power cord?

  I have not reported this Exchange Standard yet, but I want to just get an idea of what's going on?

  Thank you

• Aspire gel mouse/Touchpad V7 - 482PG when connect power cord (Windows 10)

  Greetings,

  I'm having this strange problem in my V7 after upgrade to Windows 10:

  When I plug the power cord of the keyboard and the touchpad and mouse gel (I use a Microsoft Bluetooth Mouse and touchpad in my V7 is a Synaptic).

  -If I unplug the power cord, all thaws.

  -If I plug the cord by moving the cursor, either with the mouse or the keyboard , then they don't freeze and I can work normally.

  -Of course if I start the laptop with the power cord already plugged, everything works normally and if I unplug the power cord, there is no freeze.

  The problem occurs only when the laptop runs on batteries and I plug in the power cord and the only solution is to move the mouse while plugging in the power cord. It's really annoying.

  I installed all the drivers on the Acer support and page also tried several combination of new drivers older drivers etc. This never happened in Windows 8.1.

  I don't know what else to try. I hope someone could help with this issue.

  Thank you and best regards,

  Miguel

• Pavilion Slimline lock up in sleep mode-fan works high not lights up unless I pull the power cord 1

  New HP Pavilion Slimline desktop 400-314 - mode 'sleep' sometimes cause to lock the computer, the power light is on, the fan runs at the top.  Only way to unlock the computer is to hold the power button for 5 seconds.  I wait 15-20 seconds, then press the power button to wake it up.  Immediately the computer restarts to the top with solid power light and the fan turns at the top.  The only way to break this vicious circle must first pull the power cord to the rear, wait 30 seconds and plug it in again.  This time, when I turn on the computer it goes off just fine.

  Is this a BIOS problem?  Please help as I don't have that much hair left.

  * Solved * Finally!  After 8 grueling days of pain staking agony and incessant attempts to fix this thing, I finally solved my problem.  I spent countless hours on the phone with HP support and nothing resolved.  That is: the problem with this computer locking up and sending the fan at high spin was due only with external speakers. When you reset the power system disconnected to boot the system, he would normally go for at least half a day before locking up.  I discovered that the speakers are older than 15 years. It's funny, these speakers worked fine on a desktop HP 2004 previous Pavilion running on Windows XP.  Now, it's static build-up that caused my death or something else?  As far as I know, it's that I'm a happy camper using headphones with a new system of HP that finally works.  Thank you to everyone who made suggestions.

• Power cord screen brightness variation and no brightness adjustment

  For some reason, it just happened by chance. When my power cord is inserted into my laptop instead of the increase in brightness of the screne, it decreases and her pretty dark as well and I don't know how to get back to the top.

  Anyone have any idea whats going on. Because I haven't yet touched it and it just went.

  Please can someone help, because it's very difficult because I can barely see anything.

  This product Tag number you provided is not coming as valid on the Dell site.  Please check again - I know it is difficult to read because it is so small.  So I could not check the details on your machine, but I don't know if this will help because Dell doesn't offer a lot of information on how to control hardware devices on their systems.  But if you check and send me the correct code, I'll try to cehck and see anyway.

  I found the following on the Dell site and don't know if it applies to your specific system, but this is something we have not tried, so it is worth it.

  Adjust the brightness

  "To set the screen LCD Brightness hold FN key and press the up arrow to increase the brightness.
  or just holding the key FN and press the down arrow to decrease the brightness. »

  Here is a thread in the Forum of Dell, I found on the issues of brightness with the Dell Inspiron 1545.  It includes the same procedure described above - but it includes a position that most of these problems is caused by problems with the motherboard.  I don't know if this is the problem, but if it is then, we deal with a hardware problem and not a software problem.

  I hope this helps.

  Good luck!

• All-in-one DELL power cord

  I have a Dell all in one that is about 4 years old.  The other day I started up and used for a bit.  I left to go eat and when I came back the computer was off.  I tried to push the power supply, check the power strip and made sure everything is properly connected.  No change.  I noticed that the ring of blue light around the power supply is turned off, so I unplugged the computer and the power strip.  Plugged in the power band and the light is on.  Fantastic, until what I plugged it into the computer where it was released.  I tried some other power cords (same size, etc.) and that they would also have slight shift when connected to the computer.  What can I do to fix this?

• Presario CQ20-320TU: my notebook (presario CQ20) directly turn on when I plug in the power cord without battery

  My laptop (presario CQ20-320TU) turn directly every time I plug the power cord without battery. What is the solution?

  Hi there @emonsonjaya,

  Welcome to the Forums of HP Support! It's a good place to find the help you need, so many other users, the HP experts and other members of the support staff.

  I understand that your notebook is turn on/off automatically when it is plugged. I'm happy to help you.

  I would recommend that you look at your BIOS, especially in power options and check if your BIOS has a setting option on automatically. If yes it change at your convenience.  Another option would be to update your BIOS and see if that solves it.

  Here is the page of support for your model and, if necessary, give it a try, it will automatically download the file if you click on the link. You then need to run the executable file of your current download folder.

  HPQFlash for HP Notebook System BIOS (68PHU) - Microsoft Windows-Based

  If you are having problems with an update of the BIOS, you can always restore it, using the following:

  I hope this helps.

• Power failure/loose Power Bar power cord

  I want to run a few questions in front of the members of the forum:

  Last week, my power bar power cord became loose and off the bar, which stops the computer and the monitor. The monitor has a power button function.

  Before that other devices in the power bar are turned off and unplugged, until the power bar is turned off, until the power is reconnected, until the power bar is turned off, before other devices are plugged in, and before that the devices are suppressed:

  1. in the event that the computer and the monitor will turn off (as they were in the position 'On' when they stop unexpectedly) "or" there is no 'Off' option either on the computer, the monitor, or both devices so that they can be disconnected and reconnected since they will be in the position "Off"?

  2. If the computer and the monitor are 'On' when they turn off automatically during a power failure, can they be left alone without the risk of a wave when the power is restored, OR is there a risk of a surge?

  b. is there "is" a risk of a surge because they are still in position "On", should they be disabled (or they are already in the "Off" position?) unplugged and should bar be off and unplugged then until the power is restored?

  3. in fact, during a blackout, should all appliances be turned off and disconnected, so there is no risk of a circuit breaker of the circuit limit, causing a power surge, or if all appliances can remain plugged in and left in their respective "On / Off" position since before the failure?

  Hello

  Sorry for the late reply.

  It is advisable to have the power with a surge protector bar in areas where the power failure and the cutting power is often or generally just to ensure the security of your system and in particular data. If in your region, power failure, power failure is rare, so you can avoid surge protector.

  Hope, I could answer your query. Feel free to post on the forum if you have any concerns more associated with Windows. We will be happy to help you.

  Kind regards

• Error on blue screen of Windows 8: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED on Wake-Up, posting of laptop power cord

  Question: I experience the infamous BSOD accompanied by "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED" on Windows 8, when I wake up my laptop Dell Studio 1558 from the standby mode or when I disconnect the power cord of the charger. This error message is sometimes followed "(atikmdag.sys)."

  Context: I bought my laptop (Dell Studio 1558) directly from Dell.com about two years ago. It comes with Windows 7. I have upgraded to Windows 8 (not a clean install). I then did a clean install of it when I saw the above question, although it did not fix anything. I don't have a similar such problem when I was running Windows 7.

  What I did:

  • Has undergone a new installation of Windows 8
  • The latest version of BIOS provided by the Dell Web site
  • Installed the latest versions of all the drivers from the Dell website (Windows 8 shows no missing or peripheral drivers in Device Manager unknown)

  XML file of historical reliability (Hosted on MediaFire): http://www.mediafire.com/view/?ykk5k1nkfckdf99 <-- (if="" this="" helps="" diagnose="" any="">

  I have very little technical experience. If there is additional information, I can give you which could be useful, please let me know. I look forward to your ideas.

  HA! And once again, with only a few hours of difficult things, I solved the problem myself. Provided by Dell.com video card driver is not the latest version - actually, it's a very generic version, which seems to have caused my BSOD problems.

  Given that the BSOD, sometimes accompanied the text, "(atikmdag.sys)", I googled the phrase and discovered Member that it's related to something like a core of AMD (shrug).

  Given that this seems to be video related to the card, I went back to the files-> computer (right click-> properties)-> the Device Manager and re-checked my video card driver. As mentioned in the previous paragraph, any driver I downloaded was something of very generic - it wasn't AMD for some reason any. So, I just clicked it and updated the driver. This update solves the problem, and I am now updating the driver to the latest version directly provided by AMD.

  I hope this helps others with the same question. Thanks for your point of view.

• Screen VAIO Pro 13 gradation when power cord plugged

  I just had a problem to occur on my new Pro 13 in Vaio, Windows 8.  The model number for my Vaio is SVP132A1CL.

  The problem I have is that when I plug the power cord into the machine, the screen fades until I can barely see anything.  When I pull the plug out, and the computer returns to the battery power, the display lights up to a normal level.

  I tried to restart my computer several times, and the problem does not go away.

  What should I do?

  Thank you very much.

  Kenton,

  Try this:

  1. open Windows charm and type in 'Power Options' and click on it under "settings".

  2. find the power plan that you are underway and click "change plan settings".

  3. under "Adjusting brightness of plan" adjust until you are desirable under the "battery" and "Plugged in" brightness
