Complaint driver Lenovo G550 Wi - Fi and porting Windows 8.1

Hello!

This is my first post on this forum and I hope that I have the right place to post, as I've seen other topics concerning the g550 on this forum.

I have read the discussions about the use of Windows 8 and its drivers and also problems with the wi - fi driver - it is the inability to provide a service of quality - problems with a "weak signal".

Let me put it this way:

1. at this moment I am Windows 7 64 bit and as my pilot wi - fi, I use the system planned when I installed it, it's:

So far, it is the best WiFi driver available, that gets me the best discovery of network (I see on the 10 available wi - fi networks using this).

2. to install the driver provided on the Lenovo Site's Driver, i.e. broadcom driver combined 32-bit/64-bit, the number of networks that I can connect to via wi - fi decreases from 10 to only 2 networks, one of them being my neighbor router! This is unacceptable in my opinion! Now, the speed of the network cannot deviate too much, but the pilot clearly lacks some features, because he can see only 2 instead of 10 networks - in the same place!

Now, for Windows 7 x 64 things are good, I just stick to the provided windows (4.176.75.21) driver and I can use wi - fi without any problem in the world, at a good rate of functionality and performance.

My problems are now turning to the 64 bit version of Windows 8, more precissely 8.1. I experimented with this and put aside the problem of wi - fi, which I can fix is more, everything seems fine and I'm pretty satisfied how my sistem works on win8 64-bit.

The problem:

(a) when running with the supplied Win8 driver, networks are few, just like using the driver lenovo, or even worse - a single available network - my router - 100 cm near my laptop! No other available network... Very bad.

(b) for installing the same win7 32/64 bit driver on win8, which works without compatibility issues - I get the same results as the installation of the configuration of windows 7: 2 networks are in the same place.

I read on the forums, that there may be a chance that lenovo will ship 8 to g550 windows drivers, but if they work in the same way that the current drivers for win7, they will be of no use to the expected rate of return. Can someone do something about providing better drivers, look at this problem?

I also tried to deceive win8 and port the driver win7 64 for windows 8, by extracting the location of the pilot of the iso file or windows 7 installed driver (obtained a .inf and .sys file) but ultimately I can't install it in Windows 8, even with the option 'have disk... '. ", where he finally tells me that's not a win8 supported 64-bit driver. (No signed drivers problems or displaying a message).

Now, as a solution for this, I would be grateful if someone could recommend one of the following:

(1) either a way to make the driver lenovo work better, to configure it somehow, or provide another driver for win 7-64 which can also be run on win 8 (what should be), which has good performance

(2) provide a 'port' mode the current win7 that works best with my Broadcom WiFi for windows 64-bit of 8.1 driver.

Thanks for following this!

OK, I solved my problems, this topic can be closed, as far as I'm concerned.

I'll leave here the method in which I acted, as well as any other person who is faced with the same problem will be facilitated by this guide.

Here's what I did:

(1) carries the wireless driver for windows7 - that came on the original dvd - copied three files: two .inf files and a sys file, I believe - cannot remember exactly. Anyway, you can use export driver software and select your driver and it will automatically detect and retain the necessary driver files. I have saved files and if someone needs them, pm me and I'll tell you which files they are exactly, or send them.

(2) once I got the win7 drivers, I entered my install windows 8.1 and accessible "Advanced Boot Options", which has an option available to select certain features on the next reboot-> you click on restart to see advanced features.

(3) select 'disable' in the boot options advanced, driver signing checking once they appear, after the restat. This is necessary in order to get errors that do not allow you to install the win7 driver do not.

(4) it just go to the device driver update manager, have the disc, select your .inf and there you go, just a few guests on the absence of the driver of a signature and you're ready, you can install the driver without problem.

In my case, it worked perfectly!

I did it too with other win7 drivers, and it worked also.

Tip:

If you have problems and the pilots still doesn't work, check the .inf file, it may need some modifications.

See if there is a section 6.2 NTAMD4 (this is for win8) and if it isn't, or if this article contains no lines, just create or update the same lines that you see in tights under articles 6.0 or 6.1 also in section 6.2. Then the disk method will work for your desired Windows 8.1 driver installation.

I think this can be useful for many situations, not only for this specific driver and model laptop, but for the most part are questions users driver compatibility.

  • Lenovo G550 query... Urgent

    I'm almost finalized on obtaining a G550 - the eldest cousin of the G530 notebook. I'll be racing through lenovo.com.

    Essentially on the Lenovo site,.

    Go to Products > Notebooks > laptop Lenovo value line

    You will see 3 different models for the G550. References to: Lenovo G550 - 29582CU, 29582DU and DRANK 29582

    However, I do not know the difference in the technical characteristics of the different laptops Lenovo.

    Main differences, that I could see:

    Lenovo G550 - 29582CU: Memory -2 GB PC3 - 8500 DDR3 SDRAM 1066 MHz & hard drive - 250 GB-5400 RPM

    Lenovo G550 - 29582DU: Memory -3 GB PC3 - 8500 DDR3 SDRAM 1066 MHz & hard drive - 250 GB-5400 RPM

    Lenovo G550 - 29582BU: Memory -4 GB PC3 - 8500 DDR3 SDRAM 1066 MHz & HDD - 320 GB-5400 RPM

    Apart from that, is there a difference?

    I plan to buy the G550-29582DU, but I need to know if she has a camera 1.3MP webcam and built-in bluetooth. The site of specifications does not appear to mention at all. Could someone please shed some light on this subject? Why is the lenovo site to the point?

    I need this information urgent because I need to order the book by max tonight.

    Hello BHASKARPIYA,

    Product Key Finder programs, if someone advises to use, is found only on your operating system preinstalled a Levono multiple factory facilities and will be of no use in these circumstances.

    You will need to contact Lenovo and request their assistance.

    Or a way around this is to buy a Lenovo recovery DVD to reinstall the operating system or use the built-in recovery Partition containing an image of your OS and reinstall Windows like that.

    No method requires a product key to be entered by you.

  • Driver files that run the parallel port and USB port

    In the system information utility where to look to find the parallel port and the port driver USB, name of file that manages these?

    Know the drivers specific, is only half the story.  Why you looking for these drivers?  You have problems with your parallel port or USB port?  This can be caused by problems with drivers or it could be a hardware problem (hard to diagnose a hardware problem without good parts to swap and test).  If you need to update the drivers, you must use device (not msinfo32) Manager - or maybe clicking on an executable file that loads the drivers automatically (depends on how it is sent by download).

    Go to the Device Manager by going to start / find and type Device Manager and enter and then double-click on the program icon that appears.  Check each device to a red x, yellow! or white?  These identify devices with problems probably (drivers, but also of conflict or something else).  Click on each for more details and troubleshooting tips.  If you need drivers (I assume that you want to the parallel port and USB ports), get the computer dealer or the manufacturer of the device (NOT of Microsoft Updates).  In fact, you must disable automatic updates in Windows Update driver as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Follow these steps to get the drivers: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm.  Once you have the drivers, you can install them via the Manager device as follows: http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html.  Or run the Setup program of driver provided by the vendor of the computer or the manufacturer of the device.  Be VERY careful get Vista compatible drivers for these devices are difficult to identify (they usually come with the numbers of model or something like that if they can have serial numbers) and using the wrong drivers could make the problem (whatever that is) worse.

    If you update the drivers succerssfully and the problem persists, then it is probably a hardware problem.  In this case, contact the manufacturer of your computer for technical support (hopeully it is still under warranty) or bring it to a professional computer repairman (NOT Geek Squad or one of those big store centers because they don't really know what they're doing and charge a lot for this level of expertise) to have the components tested and possibly replaced.

    I hlpe that aid.

  • Alps, Lenovo G550 & windows Vista pointing device

    Dear Sir/Madam,

    I have a lenovo G550 laptop with the following configuration:

    T6600(2.2GHz), 3 GB of RAM, 320 GB 5400 RPM HD, LCD 15.4 in 1366 x 768, Intel 4500MHD, CD-RW/DVD-RW, Broadcom 802.11bg wireless, Bluetooth, 10/100 Ethernet, Touchpad, camera, 6 c Li-ion, WinVista Home Basic 32

    I have a problem with my tocuhpad. The touchpad in question is of the Alps. At the time wherever I have to connect the charger, the touchpad stops working & the cursor becomes static.

    At the time wherever the charger is removed, the unit works normally.

    I tried & updated the driver Alps several times, even tried with system restore to the day I bought my laptop. The problem still persists.

    Pls suggest what needs to be done to solve this problem.

    Kind regards

    Abrams ' s_Maggi

    Looks like that the isn'tcompatible touchpad with your version of Vista or if you have some sort of hardware problem.  Confirm the touchpad is compatible http://www.microsoft.com/windows/compatibility/windows-vista/ or from the manufacturer.  If this is the case, then it sounds like a hardware problem and you will need to place a claim under the guarantee, while it is still new and has a.  It's a USB device?  Have you tried a different USB port?  Confirmed that it does not reach all USB devices?  It's bluetooth, the same applies as far as confirmation of what other bluetooth devices is not the same problem.  It can also be a kind of hardware with the touchpad problem, but I don't see that as likely.

    I can't think of something to see in Vista to this problem which you haven't already tried.  Well, maybe one or two things:

    Try a boot minimum http://support.microsoft.com/kb/929135.  If the problem goes away then it's just a matter of tracking down the culprit at the origin of the problem.   Follow the procedures described in the article.  Once found, remove, delete, disable or uninstall.  Once remember to put Vista in normal status, as described in the procedures. If the problem occurs in clean mode then just restore the system to normal and reboot - this solution will not work.

    Start in safe mode with network and see if the problem is here.  A result allows us to narrow down the search for the cause.

    I hope this helps.  Keep me posted.

    Good luck!

  • Lenovo G510 problem wifi and ethernet

    Hello!

    I have two Lenovo laptops, G50 and G510. The first works perfectly except the second after 10 months started yesterday which have problems with the network adapter.

    The Wi - fi button is grayed out and cannot be opened and the ethernet port can not read any cable. I tried all the solutions I found on the web (deactivation and activation devices, uninstalling and reinstalling the drivers, updating the system and the system format) but failed. The ethernet adapter does not appear in network devices after the restoration of the system to its point original (format), even after installing the drivers for the network card I found in Lenovo support site. And all this happened yesterday when the only change in the system was a windows update. However if this was the problem of the restoration of the system, update and format should have fixed the issue.

    I used windows 8.1 but now after the format I use 64-bit windows 8. Could you give advice? Could this be a hardware problem? I'm desperate here.

    Really weird that both had fault at the same time. Try the following out the battery and the power source and press the power button without any power supply 5 times. And restart again.

    If not try to work the boot in safe mode with network and see what is happening here. In the login screen hold down SHIFT key and choose reboot option. you will see Win8 advanced options.

    HP 6470 b 2nd hard drive upgrade. How fast this port works on? SATA I, II or III

    I want to put in a 60 GB SSD into the CD slot and want to see how fast it will support as this will be used for the Cache

    Thank you

    The published information is not explicit; He says only: SATA for the expansion Bay while the main hard drive Bay expressly says SATA-III. However, given that this isn't just an optical drive Bay, but also a general 'Bay expansion', it is safe to assume it of on the same SATA bus as main drive and is a SATA III interface.

    Data sheet

    6470b is also supposed to have a slot for a WSSD mSATA, but he is not described in the Manual:

    Manual

    Obviously the WSSD would work better for cache but you can use a 60 gig SSD in an expansion bay for both cache adapter. Even if the connection is SATA-II, it will be much faster to work for a cache of acceleration.
