Motherboard metallic screw holes

Hi, I have a Q on the motherboard screw holes. Only the first two screw holes have half a ring metal dotted around them and the rest have a complete ring dotted metallized, does that mean something? I know that they are to the ground, but why only a semicircle are two? Thank you

No reason, really. Only manufacturers design. I'm sure they have a reason for this internally, but as an end user, it really means nothing. Curious, though.

  • Laptop stripped screw hole?

    So, I got my HP laptop since December and often use it for school work. Recently, I noticed one of the screws fell at the bottom of the laptop. The screws that fall was directly below the hinge of the screen on the right and I noticed that the screen is not as robust recently. < br > < br > I tried the screw, the screw back in, but he just continued spinning. I tried the screw with the other holes and others live with the defective hole and all screws are working it's just a hole that seems to be broken. Any advice on how to fix this would be greatly appreciated because I don't want the screen falling.

    Look at this manual:

    Manual

    What is your laptop? The screw we're talking about is the one in the left corner higher to pages 55 and 56? That we won't in the hinge. The hinge see page 59 and 63.

    It's the part for the hinges of the screen:

    However, if you only had this laptop since December, he is likely under warranty. I'm going to bump this up to HP and see if maybe you contact via PM on this Forum. Any of the guarantees. I would like to emphasize that it is a chance to repair it cheaply and easily now before it does more damage.

  • Screw the motherboard in HP G62 b29SA - unused holes in the motherboard?

    I've been fixing G62 b29SA laptop from a friend (just replace the fan). There was some time between take apart and put back together (to get the right fan) so I do not remember if all the holes in the motherboard had screws in them. Quite a lot for screws, just spin and spin - there is no wires behind the motherboard or the screws are too small (but I don't think that I have large screws (or at least none that are not from another section (for example, battery or other).)) All the holes in the motherboard has screws?

    Hello

    No, some of them have no screws, BUT all the screws must have holes. Please see the following book to see all the screw locations (see #79 page):

  • HP Pavilion a6000n: no need for replacement motherboard - it's the standard micro ATX?

    I want to upgrade this computer and get a new card mother and CPU. Currently there is a M2N68-LA/NARRATED-GL8E made by Asus for HP. No matter what micro ATX motherboard will work, or that it has an odd size or placement of screw hole or else incompatible?

    Thank you!

    In case anyone is interested, I picked up an ASRock 970 M Pro3 AM3 mATX Motherboard AMD and a 8-core processor from AMD FX 8320E. The motherboard was a little shorter than the origian, then the bottom screw holes align. But it is strong enough and it works fine.

    There, however, no place to plug in the SD card reader, or the front firewire. I do not use firewire, so this isn't a problem, but I'll miss the SD card reader. It's one thing that I forgot to check when looking for motherboards.

  • can I change my presario cq3420an pc amd motherboard motherboard intel?

    I have a PC Compaq Presario CQ3420AN with an AMD processor, now I want to change the CPU of the pc and the card mother intel motherboard and core i5 or i7. My question is, is - it possible and if it is possible, what is the mother of Scripture?

    Yes, it's possible, but you may have problems with the locations of screw holes not macthing mounting of the new Council... may have problems with the rear plate I/O... your HP no installed OS will no longer... function and your HP recovery disks become useless for you. If you decide to accept these risks and to buy a new OS, so go ahead and have fun. Here are the current specifications for your Compaq Presario CQ3420AN desktop computer. Please make sure you get a Board microATX (9.6 "x 9.6"), which uses the DDR3-1066/1333, has an integrated graphics card (otherwise, you will need to buy a graphics card) and working with a 250 watt power supply.

  • HP S2031 20 "monitor I want to mount on the wall. What size screws to mount?

    I have a monitor HP S2031 I want to mount on the wall.  What size screws I put in the monitor to attach it to the media.

    Thank you!

    Sandy59

    The series of HP products that monitor your S2031 comes from States, "this monitor uses the compatible VESA 100 x 100 mm installation ports." This means that there should be 4 screw holes, square shaped, at the back of the monitor to 3-15/16 inch independently of the other. In the monitor screw holes should have metric threads ISO "M4" and are typically 10 mm deep. The appropriate screws (usually 10mm shorter or longer) are normally provided with the stand.

  • Can't separate the top cover to the base/motherboard to replace the RTC battery on laptop ZD8080US

    I am trying to replace the RTC on a Pavillion ZD8080US battery.  I proceeded with disassembly in step 11, page 5-33 Maintenanceand Service of Guide.  I am now unable to separate the top cover from the rest of the laptop.

    I can get the left side of the image of the base but even with what appears to be excessive force that I can't get the right separate about 1/4 "without making me concerned that I'll break the cover.   (The right side of the cover is folded about 10 degrees when I'm trying to force it).  I tried some jiggling and a few twists to see if that would open invisible conflicts but with no luck.  I used the tree of a screwdriver between the parties to try to increase the force.  All to nothing does not.

    Coverage seems to be stuck/attached to a 4 "- 5" to the top on the right side.  It acts like a screw that has not been removed.  I don't see anything when I peer into the hole when the two parties are discarded.  Is there any adhesive which can be between the parties on the right side?

    I examined the process of dismantling four times.  I counted the screws that came out.  I revamped to all the screw holes in the drawings and made sure there is no screws in the holes.

    Am I missing something?  Is there a step or a comment has been omitted in the text?  Is there a screw hidden under the model or label of Windows?  Is there one thing that others have found to accomplish this separation?

    I appreciate any help I can get.

    Thanks in advance.

    After watching the video, it looks like you missed a few screws. (certainly enough of them _ typical HP)  HP laptops must be 'broken' even if all the screws have been removed, but yours seems to just raise, so it seems that you missed a few screws.

  • Solid State Drive for Alienware 17 R2 m2 screws (2015)

    I recently bought a (Crucial) M.2 SSD for my laptop from Alienware R2 17.  The screws needed to secure the SSD for laptop is not provided, nor were they included with the laptop.  It takes a very small screw with a diameter of about 1 millimeter screw hole.

    Does anyone have any info as to the exact size and a source for obtaining this screw?

    Thank you.

    I went to Ace hardware and bought a M2, it was too long, but I was able to do the following.

    1: bought a few M2 s c r e w s (approximately 1 cm length) (sorry, dell is filtering the word s c r e w)

    2: bought 2 nuts to go on the s c r e w, when the two nuts are on the way, it is equivalent to about 3 mm long

    3: used pliers and a dremmel to compress the excess length off the coast of the s c r e w, then fact market back nuts to screw even if all threads have been affected.

    It worked for me, fit perfectly in the m2 s c r e w holes to fix the disks. Cost about $ 1.99.

  • How to replace keyboard Acer Aspire V5 - 473P

    Hello

    Several key died on the V5 keyboard - 473P for my daughter.  I searched here and everything I found was many customers complain about keyboards failed no responses, so I ordered a keyboard replacement $20 on ebay.

    My question is how to remove the Panel superior/bezel that surrounds the entire keyboard and the touchpad?  It seems that any effort to use a thin lever to lift, he would be damaged...  I have to come home from the bottom by removing the motherboard, etc.?

    I am trying to fix it cheaply, because it is hardly more under warranty and after removing the bottom of the case, I think it's come crashing down around many of the screw holes (the bottom of the case seems more expensive than the keyboard).

    Thank you.

    Hmmm... Your frame + keyboad is this one. If you look at the metal plate (bottom), it is welded by ultrasonic (grey pines resemble mushrooms) and not screwed.

    your stock mthrbrd is set on a mthrbrd platter (tempan), brand new mthrbrd will have to fixed tray to even, holes (spacers) will have to align.

Keep looking online for a visual aspect to mounting e - atx atx vs relative to each other, you can even make a comparison from the view of atx Asus and cards cards e - atx looking for mounting holes - for me, it seems that the holes of the Rampage corresponding atx & Council simply "straddles" a thumb

  • Z240 SFF (V1Z87PA): Z240 SFF - caddy/insert for disk 3,5 '' HARD in

    Hi, I am wanting to install 2 x 3.5 "hard drives in my new Z240 SFF workstation.

    There is a Bay that already came with an insert and one of the new disks slots in this very well.

    "However she looks like some sort of insertion/caddy is necessary for the Bay external/internal' shared 3.5" ", because it is too big for the Hello.adb of the player to crack. It seems that this Bay is dimensioned for a kind of optical discs.

    I called HP and their parts of people here in Australia, but no one can find the part needed.

    Can you please help?

    HP use guides drive insulation elastomer for the sliding of the hard disks in slots in SFF desktop for some time, and adding these for the screw holes of 4 threaded area of a disk HARD caused the need for the metal, as they slide is wider than a 3.5 "drive by almost exactly 1/2 inch when you consider both sides.  If you go on eBay and look for 450712-001, you'll see a bunch of these.  Form factor 3.5 "hard drives still use #6-32 (coarse thread) UNC screws, and it is this than screw silver and blue, rubber vibration insulators are at HP.

    Hard drives 2.5 "SSD and optical drives use metric threaded screws M3 instead and HP Color screws for black ones.  Those who are much more difficult to find... Note the more fine metric thread that you can see at the bottom a:

    There is a HP kit that I fell that appears to fit your form factor 3.5 "/ exit Bay that is equipped with a receiver that accepts the scrolling images we can screw a 2.5 form factor" SATA HDD or SSD in.  This can be a great way to create backups to disable storage on site, or just to have removable storage.  I use Icy Dock a device like this, and HP has used the Icy Dock products too.  That's what I use, and it fits perfectly into the HP 3.5 "form factor disk Bay on the former positions of work and also fits the 5 HP, 25 - to-3, 5" form factor converters for the new HP workstations... HERE.

    http://www.ICYDOCK.com/goods.php?id=162 I guess you would still need 4 of these arrangements of cursor to do, too.  However, you can only really one large HARD drive storage there hidden behind the front plastic.

    Included with your Z240 SFF it may be #6-32 spare isolation player guides screwed into the metal frame hidden under the Panel front of the work station... HP stored spare parts there are other SFF workstations.  Take a peek...

  • Installation of a second disk in the Qosmio F30

    Hi guys and girls :)

    I just bought the secondary hard drive for my Qosmio F30, but when I opened the drive Bay, I found that I have a problem with the installation of the drive on my hands.

    First of all, I tried to put the new drive in the Bay and press down lightly to connect with power and data connectors sata and it works perfectly, but it is impossible to move the laptop around since the disc is a bit loose in the Bay and I'm worried a little for my data and the drive itself.

    Then, I opened the first Bay and noticed that original Toshiba drive is kept in place with the help of some mount thin metal plate, which is set on the disk and the Bay with a few screws.

    I checked the Web for any revision of the F30 model that might have pictures of the Bay secondary in his State and found a few. See the photos of the same thing Im. Check this one out, it clearly shows the high Bay (sata connectors are right and not visible):
    http://www.Ferra.ru/images/179/179520.jpg

    Note a small screw hole on the left side of the Bay, clearly intended to fix the mounting plate similar with hdd secondary on the laptop. The plate which is, unfortunately, not included with my computer.

    Did someone here had the same problem and if so, how to solve?

    Hello

    As you have already said the HARD drive need a special framework that maintains the 2.5 HARD drive in the Bay.
    This frame and the screws required, you can order directly from the authorized service provider who is responsible for your country.

    I recommend talking to these guys here and explain what you need.

    Best regards

  • Installation of a second SATA HDD in 500-304nd Pavilion

    I recently bought the Office mentioned in the topic, as well as a second 1 TB SATA HDD to add. I found the connections for a second car but unable to find a place on the computer chassis to physically install the disk. What is the secret here? Do I need a room to mount the HARD drive and if so: where can I find one?

    Thanks for your response!

    I found a simple solution to mount the second HDD:
    -J' noticed that the HARD disk that comes with the computer is mounted using the holes at the bottom.
    -J' used the screw holes on both sides of the HARD drive and those identical on the second HARD drive, using four strips of metal (with screw holes on the same distance as the thickness of a HARD drive) and eight live, to link the two together.
