My Lenovo G450 has a plastic on its exhaust cover!

My Lenovo G450 has a plastic on its exhaust cover, it is OK to remove it or not? It is part of the design or remove.

My normal CPU temp is 42 c is it okey?

Here are the pictures

Is not the exhaust gases, but the air intake. Leave, it was designed that way.
And 42 degrees C is normal temp. No problem.
Welcome!

    Hello Kluggerjo,

    Thank you for reaching out to the Community Support from Apple. I know how important it must be able to count on your devices work as expected, and I have a few steps that should help resolve the behaviors you see.

    I would recommend to go by resetting your management system (SCM) controller. MSC helps control and regulate different material on your Mac, including Bluetooth systems.  This article will guide you in this process: reset the management system (SCM) controller on your Mac.

    If you still experience the issue after the test, you can test the behavior to a test user. This will help us to determine if the problem is systemic or isolated to your user account. This article will guide you in this process: How to test a question in another account on your Mac user

    If the behavior is duplicated to the test user, I'd recommend reinstalling El Capitan. This will not delete your data. To reinstall using the recovery mode, take a look at this article: How to reinstall OS X

    If you experience any problems or have any questions, please let us know. The entire community is here to help.

  • How can I move bookmarks to new Mac when the synchronization page says "this module has been removed by its author"?

    I tried to move the favorites by creating a synchronization profile, but he gave me the message "add-on has been removed by its author" and I don't know what that means. Within the forum, I found a message stating I can do by the first update for Firefox 9 or something, but my current OS is stuck with the version of Firefox 3.6.26 and will not be upgraded further until I update my OS on my newer computer. So, how can I save and move bookmarks to my new computer, a Mac with 10.6?

    You can restore a JSON backup in bookmarks (library) Manager.

    My child has its own Apple ID, throughout I would buy apps for her and she would transfer to his iPad. But since a new update she has no access to its power supplies that are on my shopping list. She is using "Video star" app?

    Hi Breda49

    iTunes purchases (free downloads are taken for granted) are permanently linked to the Apple that was used to buy ID.

    To work around this problem, you can set up sharing of family and your child. This will allow you to share all your purchases.

  • Unknown device & network controller in device for Lenovo G450 Manager

    Hi, in my lenovo G450 - with Chipset Intel - 3 GB of RAM (no external graphics card),

    I see an unknown device with question mark on device Manager, under Win XP. Further clicking on properties of the device tell me that--

    Device type: Other Devices

    Manufacturer: unknown

    Location: On Microsoft ACPI - controller embedded compatible.

    I installed all the drivers and that you have not installed the external devices such as USB etc.

    I don't get what device it could be.

    Network controller shows also with question mark, even after installing Broadcom Ethernet Driver for XP.

    Kindly help me what to do?

    Is there any order, where we need to install the drivers.

    Re-install the drivers ethernet and power management.

  • Windows has a mind of its own?

    A few weeks before that I demoted Win.8.1 of Win8. I can't support either.

    Tonight, I get a message that my computer needs to reboot for Win.8.1 can complete loading.

    I never said I wanted to move to 8.1. Windows has a mind of its own

    and upgrades to the next version without worrying about whether you want it or not?

    Well, I guess I'm stuck with 8.1.

    This happened to someone else?
    Bob

    It apparently * a * is happened to others, even though I have yet to see it happen first-hand (or with anyone I help/manage personally who chose to not move to 8.1 for a reason any.)

    If most of the 8/8.1 aversion is the interface - 8.1 is the best choice because it gives more options to customize without know entirely too much about the inner workings.

    If you don't mind a suggestion - check out the first post in this discussion to see if some of the suggested changes would help you with your discomfort with Windows 8.1 or not...

  • The document has been changed since its creation and use of the extended functionality is no longer available

    I have Adobe Acrobat Reader DC 2015.016.20039 on my system. I filled a form using Foxit Reader. When I tried to open the form with Adobe Acrobat Reader DC I received the error "the document enabled extended in Adobe Acrobat Reader DC features. The document has been changed since its creation and use of the extended functionality is no longer available. Please contact the author for the original version of this document.

    I tried other PDF programs, no problem at the opening of this form.

    Ashampoo_Snap_2016.05.17_02h01m01s_002_.png

    Function "Activation reader" comes from the original shape, and it's essentially a digital signature. It is specific for the free product of Viewer PDF by Adobe (aka Adobe (Acrobat) Reader).

    The problem is that only Adobe products are able to (re) make these documents without breaking the seal of the digital signature.

    So, what happened in your case is the Foxit Viewer broke the seal during the recording of back and what's. Using Acrobat, you can save a copy of the form, and then continue will fill. Otherwise, you will be better off to start over, but stay with viewers Adobe PDF all the time, working with the form, or with a different Viewer, once again all the time you work with the shape.

    BTW, player XI and most recent no. have more need of extended for more rights blocked by previous versions of Reader. This is not enough in this case; only, it would be useful for the sender of the form.

    Update (after rereading of the original message): if it's just for viewing or print the form, you can ignore this message. You can also try to save just, you have a version of player who no longer has the rights extended (at your risk).

    I hope this can help.

  • Lenovo G450 blocked supervisor password

    Dear Sirs,

    I tried to remove the supervisor password in the BIOS by writing the old password, pressing 'ENTER' button twicely, then restart my laptop. After that I still see the request of password, but it is not related with my old password and password empty. So my laptop data bloked.

    I want to get suggestions and hear, it's a common situation or what I had done inproperly? If so, then why IBM does not preclude any statement and that pacriculary can help me the IBM support?

    Recently, I posted this problem, but it was closed by the moderator because of "this subject is not allowed to be discussed here, as described in the forum rules. I understand and thank him for the proposed support link, but I have found no support contacts throw in my country (Ukraine). I ask everyone to consult me to keep the rules!

    If your information is under the rules, please answer me by ruslan.voroschuk (at) mail.ru!

    Thank you!

    The problem has been resolved in itself!

    The problem is inspired by leaving it on the 'request password' in the BIOS menu. So after having erased the password of my laptop continues to ask me the supervisor password, I had put forward and remembers correctly.

    But my supervisor password has some symbols such as ',' and it's up to 7 symbols length. I was confused when I heard noises by entering the password and stopped my attempt. After you have entered the correct password not taking into account the annoying sounds, I've unlocked my phone!

    Topics on the fourm causes of 'noise' show me the right way.

    Sorry to put on a misunderstanding!

    I liked my G450 and your nice forum!

    Thank you all!

  • 6457 - Lenovo T61p has suddenly stopped working!

    My Lenovo T61p 6457 has suddenly stopped working.

    When I turn it on I see the power and drive green lights HARD turns on and since another computer on my network I can access individual files on the hard drive the T61p.

    However when I connect the T61p via a VGA cable for an external monitor to work I don't see Windows or images on the screen!

    Do you think it is just a problem with the screen or is there something else?

    The screen currently installed on the T61p 6457 is WSXGA 1680 x 1050 (Samsung LTN154P2-LO5).

    I found a job WUXGA 1920 x 1200 with inverter and cable in the box of original case Lenovo T61p high - that will work in my T61p?
