• printer do not wake off mode 'sleep' and does not turn off when the Start button / stop pressed or pushed.

  HP printer all-in-one B210a win 7 64 bit.

  no error message just don't wake up from power saving mode and does not turn off when the power button is pressed. must be disconnected and then turned back on. works fine until the power saving mode he did go to sleep then not answer the test print command or Toolbox controls.  power saving mode is turned off, but still goes to sleep.

  First, you will need to make sure that the printer is under warranty.  You can do it here.  So, if you are in warranty, you must contact HP at 1-800-474-6836 and the United States in computer science, international users click here.

• Satellite L550-1CW does not start by pressing the power button / stop

  I have a Toshiba Satellite L550-1cw that won't start, lights up when I press the power button all the lights at the front, the fan starts and he is looking for a HARD drive for about 2 seconds and then stops.

  I tried a new HARD drive, but the same happens.
  I was told that all this must be ignored and buy a new one that is not an option.
  I love this laptop and want to run again as this is the best I have ever owned.

  Help, please

  Andrew

  Can you give us more information on this vulnerability?
  You see something on the screen after pressing the power button?
  You can access the BIOS by pressing the F2 key immediately after switching on the device?

  Despite this whole issue, I think that if nothing is visible on the screen it could be a serious problem with one of the following: RAM modules, motherboard, CPU/GPU.

  From my experience the RAM memory modules are not very expensive (2nd hand might be good enough) and the replacement isn t very delicate in the case where the faulty memory causes this problem, the laptop could be set for a little money.

  But in case of problems of motherboard, laptop repair procedure could be very expensive.

• Pavilion dv9700: laptop does not turn on but lights flash

  I have a Pavilion DV9700, service tag dv9925r. When I turn on the power, the power led and the led on top flash, I can hear the fan and drive spinning, but the screen stays black and after one or two seconds the lights out, but then continue to Flash on then close. When, I hear the fan running.

  What I've tried;

  Hung still no display on an external monitor

  Removed and reinstall the memory and hard drive, not good.

  Tried the hard reset, not good.

  I put another hard drive just to see if the disc was not, but no difference.

  There is no audible beeps at all. It does not seem to go through the checkpoint.

  The laptop is dead?

• 850 - 009na M1Z34EA #ABU: CPU fan for the 850-009na feel like Phoenix does not turn down after the power - on self test unless the BIOS is entered

  Hello

  I have posted responses to other posts on this topic, but thought I'd start a new thread to gather my conclusions. I'm sorry for a trial

  This PC is virtually brand new (only a few weeks now) and otherwise perform exceptionally.

  Basically, if the machine is disconnected from the power grid (i.e. the power is off at the plug or the power cord removed), when the machine is supplied then the CPU fan turns over 2000 rpm and stays there. All the other PC that I do this too, but the fan will slow down after turning upward. I know that this is done as part of the POST to check that the fan is running.

  If I go into any installation of seed, start-up or BIOS for example (i.e. by pressing ESC or F10 etc.), the fan will slow down immediately up to 700 rpm. It will stay like that until the next time the machine is started against the cold. If I shut down the PC - watch or stop - but do not cut the power supply, then the next time the machine is started, the fan is still about 700 rpm. It is not to turn up to 2 k + RPM when lit.

  As soon as I unplug, then the next time the PC boots, it will turn to the top and I have to repeat steps - off, boot, enter the BIOS, exit and continue. It is something to do with the cold start.

  Note that I don't have to do anything in the start menu - I for example go to the BIOS settings, exit without saving the changes, and the fan will still slow. It's going in the boot sector that slows down the fan.

  When the PC started out-of-the-box, I opted for the upgrade to Windows 10 during installation. I have read in various places that people had experienced after the upgrade, so I reset the machine to factory settings (Win 8.1) and have not upgraded, but the problem persisted. However convinces me that Windows 10 has been removed completely, as when I went to restore the backup image (i.e. dating back to what I had before the factory reset) there are references to 10 Windows (for example, it says 'Continue to Windows 10' as well as various food options). I do not understand UEFI so I don't know if that was involved.

  I tried to change the power plan options "Processor power management-> cooling system strategy" on the liabilities side, but no joy there.

  I think that the fan and sensors work, based on the findings below. These readings of temp and fan are taken from AIDA64

  After starting cold (current was cut, without entering the BIOS), machine runs dry without load

  

  Exactly the same thing--starting in cold, but go in the BIOS, do nothing and continue. Once again, no load

  

  This is after power off and resarting, but to let the PC network

  

  After the above, I used Prime95 to put the CPU support (use of 95-100%), and after an hour, the readings are:

  

  Note that even so, the fan was not particularly strong, but it's at 2222 rpm as in the first reading.

  If I play at 4K (the whole point of the PC ) the CPU so far got very warm, the GPU is but his fan turns up as planned.

  In conclusion, it seems that the POST has a problem because it does not slow down the fan after the test.

  I can live with let the machine always plugged into the sector (for example, most of the time) and I guess that's what most people do, but I would like to know what the problem is (for example if it's really something 10 Windows, or a bug in the BIOS/UEFI)

  Thank you very much!

  John

  Explain you a lot of people who maybe have returned their system immediately because of this? Others might judge normal sound. Not irritable average is not coming here to complain. Others might judge her so little. They simply don't like. You will never convince me that is not a BIOS problem. As the problem resolves itself when you enter manually each time. It can be reproduced every time.

• Pavilion DV7-3162nr: HP Pavilion DV7-3162nr does not turn on and the battery light flashes during charging

  I was upgrading my HP DV7-3162nr for windows 10 when all of a sudden the laptop stopped working and would not turn.

  The power adapter is plugged in and battery led was flashing. Now battery led does not at all depend on. When I press the Start button the laptop would try to start then turn off after about one second. However most of the time when when I press the button nothing happens.

  I took out the battery and tried to immediately start the alternating current, but the laptop is like there is no power. The led near the power connector is on the AC adapter is plugged in. I checked the tension between the adapter and it is correct to about 19 volts, I even loaded to 1.5 Amps and voltage remained close to 19 volts. I tried now on the button for more than one minute with applied power (no battery or AC) and no change when I tried to start with just AC.  The battery is old, but shouldn't the laptop run on just the AC adapter with the battery installed? I do not think that windows 10 has done this, but it's a weird coincidense that he died during the upgrade.

  I read about simular problems with flags of HP but nothing exactly like it.  The fact that I can not turn on the laptop with just the adapter seems to be a problem really bad.

  Anyone has any ideas I can try to let me know

  I was able to fix my laptop.

  I thought that it must be a hardware problem, because the laptop would not run just the adapter. And the adapter was good, as I said, he had the right voltage and can support the load.  So after looking at a lot of U tube videos on how to disassemble laptops and looking for schematics on the laptop which I couldn't find. I disassembled the laptop and a beep on the load circuit and it showing. What I found, it was a bad MosFet at the beginning of the charging circuit. The MosFet P/N P0603BDG has shorted door to the Source.  I was able to get the part of China via Ebay for less than $5.00 total and it took a week to arrive.

  Now, the laptop charging the new battery and works very well. I could have found the bad MosFet faster if I had diagrams. Does anyone know if it is possible to get the schematics for this HP laptop? I found a manual and it helped a bit to disassemble the laptop, but he had nothing on the main map.

  This problem is now solved hope it helps someone out there.

• My dell studio 1555 laptop does not turn on

  Hello

  Does not turn my dell studio 1555 laptop computer. I tried all the troubleshooting option provided in the dell forums.

  Here are the steps:

  • Disconnected all external devices on the computer, including the battery and the AC adapter / CC.
  • Press and hold the power button for 20 seconds.
  • Reconnected the battery and the adapter.

  After checking all the options of this still my laptop does not turn. I am not able by any beeps as well.

  I even checked the video output connect my laptop with an HDMI cable on other devices (TV). The screen is blank.

  Kindly let me know what we can do more.

  PS: I have no warranty for my laptop.

  Thank you

  Kirti.

  Check that the LED on the adapter lights before plugging the end of the book.  If this is not the case, replace the card.

  Try without the battery - if it will then light up, the battery is bad.

  Unplug, remove the battery, press power for 30 seconds and remove and reinstall the bars of memory.  Try again.

  If it lights with a good map and without the battery, replace the motherboard.

  The image (it back up to an external drive as full image) and reinstall Windows XP, update, drivers and everything.  Install any plugins that you NEED to do all that you see here that the bat hurt.  If the problem no longer exists, something has gone wrong with your system from before (corrupt files or your cleaning is not as complete as you think) and if the problem persists - probably something to do with the material. In all cases, you can return to the image if you wish.

  To the extent wherever it is the registry, I must ask, * how * you have come to this conclusion?  Not that I'm defending something - I was wondering what you did to decide who is not your registry database?  (Side: I agree with you.)

  That's what * I * would call cleaning and optimization of a Windows XP machine:

  Search for malware:

  Download, install, execute, update and perform analyses complete system with the two following applications:

  • MalwareBytes (FREE)
  • SuperAntiSpyware (FREE)

  Remove anything they find. Reboot when necessary. (You can uninstall one or both when finished.)

  Search online with eSet Online Scanner.

  The less you have to run all the time, most things you want to run will perform:

  Use Autoruns to understand this all starts when your computer's / when you log in. Look for whatever it is you do not know using Google (or ask here.) You can hopefully figure out if there are things from when your computer does (or connect) you don't not need and then configure them (through their own built-in mechanisms is the preferred method) so they do not - start using your resources without reason.

  You can download and use Process Explorer to see exactly what is taking your time processor/CPU and memory. This can help you to identify applications that you might want to consider alternatives for and get rid of all together.

  Do a house cleaning and the dust of this hard drive:

  You can free up disk space (will also help get rid of the things that you do not use) through the following steps:

  Windows XP should take between 4.5 and 9 GB * with * an Office suite, editing Photo software, alternative Internet browser (s), various Internet plugins and a host of other things installed.

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.
  3. highlight one of your readers (or C: If you only) and click on the button "settings".
  4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
  5. click on OK. Then click OK again.

  You can control the amount of space used may or may not temporary Internet files...

  Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

  -Open a copy of Microsoft Internet Explorer.
  -Select TOOLS - Internet Options.
  -On the general tab in the section 'Temporary Internet files', follow these steps:
  -Click on 'Delete the Cookies' (click OK)
  -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
  -Click OK.
  -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
  -Once it's done, click OK, close Internet Explorer, open Internet Explorer.

  I found another workaround solution;
  Remove the AC adapter and battery
  Leave the laptop disconnected for long periods. I guess you should wait a few hours.
  Then reconnect the battery and ac adapter.
  Then try to turn on the device

  Put it on wait ten minutes if the phone did not come one, then hold down the sleep/Home button until you see the apple logo and then release, make sure that the phone is still connected to the charger.

  Hello

  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.
