HP laptop Pavilion 17-e040us - Possible fan problem

Hi all.  I think I have a fan problem.  The fan seems to run all the time... at least for the past 3 or raining days, but not fort, with air alternating hot and cold, of the events.  I looked at the events surrounding the outside of the computer and it does not seem to show the accumulation of dust... but even with appropriate glasses, I'm not able to see if there is dust or not... is old or in my case being old causes sight problems!  I also used the diagnostic software to see if any hardware has failed.  The results showed that the computer hardware is correct.

Then you clean the vents (the article says that it is acceptable to use a hair dryer)?  In addition, open the back cover of the laptop to clean the fan inside if it has dust?

Article also says to turn off the computer and unplug the power adapter before spraying compressed air.  Also if you use a blow dryer on the cool setting?  If so, what is the power adapter and how to disconnect it?

Right now I am using the wired option.  I just need to remove the power cord at the back of the router to disconnect.  However, then the computer is wireless... How to turn off the wireless feature... so I can clean the fan/vents?

Thank you.  I really don't miss my XP version!

By blowing air through the vents of your laptop, you are forcing air through the fan. In a laptop, this remove most of the dirt and allow for better air circulation and cooling. This isn't the case with a desktop computer and that's why the video demostates office clean the fan.

I suggest removing the battery is because with it in place, you can accidentally turn on the computer. With the sector/charger adapter unplugged and the battery removed, there is no chance of the computer starts.

If you have any other questions, feel free to ask.

  • HP Pavilion dv9550eo (clicking sound) fan problem

    Two months ago I have vaccumed the fan, but don't forget to keep the fan. If the fan has got a very high SPEED while I vaccumed. When I started my PC after that the fan suddenly begins to make a "rattling noise" and the RPM is extremely high. I used my computer to much a game earlier, and rpm and noise were never like that. What can be the problem? Is the bearings in the fan broken? How can I fix?

    Can I buy a new fan or the need of a whole new radiator? The partnumber anyone so I can order a new part?

  • Laptop Pavilion g6 troubled cooling fan

    My laptop (1c58dx g6) guard stop and gives me an error message on the cooling fan. The fan has completely stopped working or slowed down a lot. It's more as it comes up for a second and then stops completely for a few seconds again and again. I don't know if that's how the fans usually ruin if they are blocked or not. So, I spent all last night holding my cell phone out to join fan cooling to clean junk out of it and then put it back together again. It's not like there was there to cause problems, but I cleaned to the best of my ability without taking the fan itself out. However, it was without result. The same thing happens again. Do you think that if I took part the fan that I could find and remove the Junk incriminated in the fan, or do you think the problem is something else? If you disassemble the fan itself can help, could you tell me all instructions on remove and put back together, again please?

    Hello @BL00 ,

    Welcome to the HP Forums!

    I understand that you have some problems of fan and are wondering how to remove it for better cleaning.

    Here is a guide who can guide you safely remove the fan: HP Pavilion G6 Notebook PC - Maintenance and Service of Guide. You will find the steps begin on page 77.

    It might also help to go through this document, but it seems that you already have most of this: reduce the heat inside the PC to prevent overheating.

    In fact, you need to replace the fan altogether. References are available in the guide above and you can find them among a wide range of online providers. If your laptop is still under warranty, you can also contact the HP support by phone for parts or service options. You can contact HP Technical Support at 1-800-474-6836 in North America.

  • Error 90 b - cooling fan problem

    Hello

    A few days ago I started getting message, with a cooling fan problem, error 90 b

    But this error was only occurring when I started my laptop after 5-6 hours

    I mean when I started this morning, at the first moment it showed this error, and when it will stop automatically (it says, ENTER to continue starting or it will stop in 10 or 15 seconds) and then I start it again, but this time, no error started end

    So guyz, I wanted to know whether hardware or software problem or something else

    Still my warranty period which goes, so should I goto HP support center?

    I'm on HP Pavilion dv6

    It is material but may be repairable before you send it. Bend over a paperclip and stick it through the grid to hold the fan and prevent it from running out of control and blow compressed air in the grid to dislodge any dirt or dust that can be hung up the fan. If it does not the fan may need to be replaced.

  • Qosmio G50 - problem with graphics card or fan problem?

    Over the last year, I bought myself a Qosmio G50 at the beginning it seemed very nice and kool or so I thought until after the expiration of the first year, I noticed a small problem with my laptop.

    1. my fans are loud and sometimes they overheat, whats worse I can't clean my computer laptop but because fans note my fans were quite
    the first year to have my laptop, so I have no idea why they are noisy, they shouldn't be doing this right?

    2. now that my fans are not clean, I'm in trouble, play with my video games, at least those who need the video card.

    3. while I play my games I have noticed how the fans or the video card video game a little speed and not the game, but you get the idea, it was bugs me for everything now.

    Here is my last question for Toshiba support here
    Qosmio G50 laptop Fans can be replaced? If so, how much would it cost?

    What are the causes of the nose of the fans to make it so hard?

    More help on my problem would be welcome.

    If you have any questions for Toshiba support service then you are on the wrong place here. This is the forum user.
    Maybe you should contact the nearest authorized service provider and ask it.

    They can clean up your computer is turned on in a professional manner. After cleaning of the cooling and ventilation of cooling grid will be dust-free and run with low speed.
    The material can be cooled properly.

  • HP laptop Pavilion g6 - stall wifi connection

    I got a g6 HP laptop Pavilion for nearly a year, running on Windows 8.1

    I am of people (and more) loss of connection wifi to router - all other devices using the same WiFi (desktop, nexus, samsung phone phone) all keep them the connection and internet access, but the Pavilion keeps falling.

    Other related posts on this forum suggested the issue may be an outdated driver - how can I check that?

    Hello again Pragmata,

    It is good to hear from you again!

    As the problem persists after that you turn off the laptop, I also recommend following the steps below to correct this problem:

    1. open DEVICE MANAGER

    2. open the NETWORK CARDS

    3. right click on the WiFi adapter for the pc and left click on PROPERTIES

    4. click on POWER up.

    5 remove the check mark beside: ALLOW the COMPUTER TO TURN THIS DEVICE SAVE START STOP

    6. click on OK

    7. close DEVICE MANAGER and test.

    NOTE: There may also be checked under the CONTROLLER FAMILY (for example. Realtek PCIe GBE Family Controller which would belong to the title of the WiFi card). If so, you can remove the check mark next to ALLOW the COMPUTER TO TURN this DEVICE FOR SAVE OFF.

    Please re-post with the results of your troubleshooting, and I look forward to your response!

  • HP Pavilion 15 t-n200: HP Pavilion 15 t n200 - ANOTHER problem of flag - DISPLAY messed...

    So, I bought laptops 15 t-n200 of TWO 2 HP Pavilion last year, and here it is the specs:

    • S window 7 Home Premium 64
    • 4th generation Intel® Core™ i5-4200U processor + Intel® HD graphics card
    • diagonal 15.6-inch BrightView HD (1366 x 768) LED backlit
    • 8 GB of DDR3 (1 Dimm) system memory
    • 750 GB 5400 RPM hard drive
    • No Softw are additional Office
    • Security Softw are trial
    • Battery 4 cells Lithium-Ion
    • SuperMulti 8 X DVD +/-R/RW w ith Support Double layer
    • Standard keyboard (black)
    • Webcam HP TrueVision HD w ith Dual digital Microphone (black mineral)
    • 802.11b/g/n WLAN [1 X 1]

    The first of the NIC card went bad, then had to send it back and they sent me a HP Envy.  It works very well.

    Now, the second cell of 15 t-n200 HP Pavilion, less used because an employee currently, screen shows horizontal white lines across the entire screen.

    I have:

    1. Uninstalled/Reinstalled the graphics card
    2. Restored to a previous restore point
    3. It was restarted in safe mode and result of the diagnostic stuff
    4. Rebotted and restarted

    The lines went away for about 30 minutes after the restoration of windows, but finally they came back and the screen is more often just now.

    I have a beautiful, like new, HP Pavilion 15 t-n200 that seems to be DEFECTIVE. Ironically, just like this one.

    I remember at the time where Dell was the big name in portable PC.  When I worked for GE, Dell embarquerions computers laptops new for us, for our Department that would not last a month, or the keyboard could not be broken up (even if the box was not), etc.

    I promised myself after that experience of being a man of HP, but it's flat disappointing...  Two flags which broke out, before the expiry of the guarantee and the other after the expiration of the warranty...

    Even if I don't feel like there is nothing I can do at this point, I am open to all to give a final blow to this laptop.  Anyone have any ideas?

    I am very disappointed with HP... There, the quality became atrocious over the years.  Problem after problem... I'm tired of it...  If this issue cannot be solved, I'll take my business to Toshiba... or even Lenovo (IBM Stinkpads)...

    THE SOLUTION TO THIS PROBLEM IS:

    .. .drum roll... NOT to BUY HP LAPTOP PAVILION... NEVER!

    I have been contacted by a case manager, but it doesn't have a lot of help, as all he could do was offer repair me the laptop at a price that is outrageous compared to the initial cost of the laptop.

    But why would I want a laptop faulty return?  This is the reason why HP WILL NOT receive any business from me in the future.

    I bought TWO 2 HP Pavilion 15 t - n200 Notebooks (exact same configurations - exactly what was suggested):

    -Purchased directly from the HP Store homepage

    -Both bought within two months of the other

    -Both shipped from China

    -The two end up having defective parts, giving them a useful life of less than a year for a single and a little more than one year for each other.

    -Laptop 1 had a faulty NIC card, 2 portable has a defective video card or the LCD

    -Two laptops were PC replacements and barely moved.

    What are the chances that BOTH of these books have defective parts?

    HP does not seem to think nothing of it, I have increased my case and their climbing team, which is supposed to meet before the end of the next business day, NEVER communicated with me when I told him my concerns of a range of defective products and/or the production cycle...

    If you have this problem, it is my view that the same given the support of options gives you, you unfortunately bought a LEMON.  At least, that's how I think of her and lost nearly $600.  Never again...

  • HP Pavilion G4 1003-TX: HP Pavilion G4 1003-TX adapter problem

    Hello... I have HP pavilion 1003TX G4 laptop who cureently having graphic card problem. Technician in my place, said that is caused by the solder connection on my Radeon graphics card.  He said, it can be repaired, but the same problem will happen again soon unless I replaced my graphics card with a new.

    In my laptop, I have a Radeon and Intel graphics card which I can move freely. My question is, if I change my Radeon for my Intel graphics card, is solved my problem of graphics card? Is my laptop still won't last long, unless I buy the new graphics card?

    Please help me if you know the answer. Thank you

    There is no way to pass. Two video systems are part of an electronic circuit integrated on the motherboard and if the Radeon graphics chip is bad the whole motherboard is bad. I wonder how the motherboard has been repaired? A lot of "technicians" use a very crude method of just warm up the video chip with a heat gun instead of making a more complicated "reball" of the video chip. A hack job is the last 3 months, but a good reball will last a year or more.

    Once the video chip was repaired once it probably cannot be done again if your only option now is a replacement motherboard or a new laptop.
