HELP: Lenovo K450 Desktop Wireless LAN Problems?

I recently bought a lenovo k450 desktop, first desktop i have bought, and ever had, ever since i've bought this desktop the Speed.net speeds are 1/2 of the speeds my laptop gives off. My Laptop gives a 54.0 Mbps Speed LAN connection, and my new desktop is giving off 36.0 Mbps , my friend has the same computer, and gets 48.0 Mbps , My desktop is a normal 3.00 Download, and always the same upload on both, 5.80 , my laptop is a normal 6.00-7.00ish download mostly, so if anyone knows how i can fix this i would greatly appreciate that. http://gyazo.com/845451ab21c05605e942081388eb9952 Heres a picture of my current LAN Speed

Hello James,
thank you very much for your help.
I did all the mentioned steps and first it seems that the WLan was working.
It wasn´t as fast as expected, but I could surf in the internet.
After another restart OSX asked me for the password of my router and then I got the old problems: Very very very very slow connection, broken connections and finnaly no connection via WLan.
Do you - or anyone else - have another idea what I can do to fix this f.... problem?
Thanks,
Stefan

Lenovo H535 Desktop Win 8.1 USB 3.0 Disconnecting Issue

OK. I just bought this Lenovo H535 desktop in early September and this OS has been driving me CRAZY. After spending well over a month and performing maybe 7 clean installations, I'm trying to get this stupid & worthless operating system to work correctly, I'm left with one issue(that I know of) I cannot resolve.
Now that I've upgraded Win 8.1 core (clean install from RTM iso), my USB 3.0 external Fantom Greendrive is disconnecting on it's own. In Windows 8, it stays connected FOR EVER, but in Windows 8.1, I'm having issues. Of course the drive is plugged into the back of the PC and I've tried each of the USB 3.0 ports. One thing I can tell you is, this USB 3.0 device disconnects at the same exact time each time..... NOT RANDOMLY. Disconnects that the same time provided I don't change any of the PC's hardware settings. And I'm now troubleshooting this isse on a freshly installed system:
Normally the Fantom HD disconnects in 7 min 15 sec. I have tried:
Disabling the USB Selective Suspend in the Power Options - Doesn't work. USB 3.0 disconnects in 7 min 15 sec.
Also disabled the HD from sleeping also in the same panel.- Doesn't work. USB 3.0 disconnects in 7 min 15 sec..
Regardless of what I'm doing on the computer in the background, it always disconnects at the same exact time.
Tried disabling the Power service all together(no power options.) - USB 3.0 disconnects in 22 min 45 sec.
I turn Power Service back on and disabled about 10 uneeded services - USB 3.0 disconnects in 7 min 15 sec..
OK, after installing ANOTHER fresh install of Win 8.1, and installing the Windows Updates, BUT this time I have installed ALL updated device drivers from the Lenovo support site for Win 8.1 Even though most devices were running ok with MS generic drivers. I thought that the installation of a new Chipset Driver and USB Filter Driver would fix the issue. Nope. I GET THE SAME DARN DISCONNECTING.
Conclusion. In Windows 8 Core, the USB 3.0 external Fantom HD stays connected for EVER but in Win 8.1 core- it's disconnecting. That leads me to believe that Windows 8.1 core has some bugs. With my limited experience, it seems that there is NOT physical power shortage. but a Windows 8.1 bug. (works good in windows 8) Another thing that may be related is with Win 8.1, the PC will not go to sleep. Sleeping issues is defitely a bug
Everyone on most sites I've read said to install the chipset drivers and it will work fine. Well, with me, everything is the exception.
Can the Fantom HD disonnecting on it's own all the time, corrupt anything on it?
Does anyone have any resolve or any additional info on this???? I really would appreciate it. I kind of like Win 8.1 better than 8 because it's the lesser of 2 evils. Oh, I'm glad to a member in the forum

Hello again. I found the solution!! Simplly clean installing Windows 7pro and getting rid of Windows 8 did the trick. the USB 3.0 hard drive stays connected as long as I like. The 3.0 speeds are great also. It's a shame I bought Windows 8 on a pre-installed system, but I'm never gonna use it. I like the fact that Lenovo provided the Windows 7 Drivers on the support website for my H535 which gave me the opportunity to install OEM and AMD drivers as opposed to microsoft generic drivers.
Now I need to find a product key. I don't know where to look or if any product key work work. Would buying a Retail box work? Seems like overkill just for a key. Can I buy a downloadable product product key for a cheaper price? Thanks
To add: I found out that the Windows 7 pro x64 retail boxes (DVD, COA, KEY) are about $130-$140. I don't think I want to buy a key without the COA which is proof that your key is authentic.

Lenovo 8258J4U desktop

I have a Lenovo 8258J4U desktop. It currently has a AMD sempron 3000+ socket 754 CPU and a K8M800-M3 motherboard. I would like to upgrade the CPU to an AMD Athlon 64 3200+ 512KB socket 754 CPU.
Are there any special dip switches settings I need to know before I can upgrade the CPU?
Thanks inadvance.

hi Davidgll,
On the dvd drive's faceplate, can you check if there's a small pinhole where you can force eject the disc tray by inserting a paperclip into it (see image below):

Let me know your findings,

Lenovo H420 Desktop takes over 5 mins to boot up

Hi,
We have a Lenovo H420 desktop that takes over 3 mins to boot up. After you switch it on, the monitor displays a black screen with 'Lenovo' in white writing and remains with this screen for minutes on end seemingly doing nothing (hard drive cannot be heard working and it's activity light doesn't flash). After about 3 minutes Windows 7 suddenly loads in a matter of seconds.
Any ideas what is wrong? Is this normal?
We've only had this computer for about 3 months and it has been doing it since we bought it. We reset the computer back to its factory settings but that hasn't changed anything. Bios doesn't seem to be accessible as no startup screen saying press del for setup etc shows.
Kaspersky and Malwarebytes doesn't show any nasties.
Thanks
Solved!

Lenovo H515s desktop **** FALSE ADVERTISING ****

Purchased H515s desktop over a week ago, when opening box I noticed there was no wireless keyboard and mouse. I contacted Lenovo or should I say Digital River which deals with their sales to be told someone would call me back. I received no call up until monday so I called them again only to be told that this particular model does not come with wireless keyboard and mouse. I informed them yet again that this model was being advertised as including wireless keyboard and mouse. The lady said she had had this query before and would escalate the complaint and someone would contact me within forty eight hours. still no call so I called them only to be told they are still awaiting a response from Lenovo. Do I keep it as I have no faith in their customer service, do I return it and waste their money on delivery and return fees (it probably would be cheaper just to send me the items) or do I contact Trading Standards. Lets face it if they know about the false advertising of a product they are obviously not interested in customer care and would adjust their website or would someone please like to contact me from Lenovo.

TexanAviator,
Hmm. You were going by these pics from the website? Does the system have the patterned cover as shown in the photos, or is it just solid gloss black? The photo looks to me like it conveys some level of gloss. Was it more than you expected?
I see the hinges in the photo are silver? Perhaps they wound up being painted during production?
Would you say your biggest concern is the difference in touchpad or the cover & hinge appearance?
You are welcome to file a formal complaint, and I can certainly help you do this. Please send me a private message with your name, address, phone, sales order number and the serial number from the bottom of the unit.
Aside from these visual differences, how does the system perform as a computer? How is the appearance of the display, the feel of the keyboard, and the overall operation?
We definitely appreciate your feedback,
Best regards,
Mark

hi robyone69,
Welcome to the Lenovo Community.
If you have the Lenovo J105 (types 8458, 8459, and 8460), you can find the connector layout under page 118 on the Hardware Maintenance Manual.
Spoiler (Highlight to read)
If the layout is different, you can find the user guide / maintenance manual on the lenovo suport.site (http://support.lenovo.com). Sample search:

Lenovo K450 Upgrades

Hi, I want to upgrade my power supply to a 600w PSU to support a new graphics card. I would like to have either a GeForce gtx 750 or 760. Or maybe a r7 260X. How would I go about doing this since I heard the Lenovo IdeaCentre K450 can only support so high of a GPU. But I also heard that there was a way to bypass this and be able to use higher end GPUs. If I could bypass it, I would like to know how. I would appreciate some help in this matter, thanks. (Btw I purchased this in March 2014, so it has the new Haswell CPU) and since it's the new version, could it now take up to the geforce gtx 750?

hi JamesA95,
Welcome to Lenovo Community Forums!
According to this Tech specs
Your system sould support 8GB and this Laptop Has two Memory banks, so You should be able to do that RAM setup.
http://shop.lenovo.com/us/en/laptops/essential/g-series/g580/#techspecs
Fro RAM I personally recommend this
http://images.crucial.com/upgrade/Lenovo-memory/Essential+%2F+Value+Line/Lenovo+G580-upgrades.html
Installing SSD This is ver doable.
have the SSD installed where the HDD is now and put the ssd on the Optical Drive slot using a Caddy for 2.5"
Your main Concern here is to Migrate the HDD content to the SSD and losing the Onekey REcovery Option in The Process.
Regards

Lenovo H50 Desktop Help

Hi, I recently brought a desktop about 2 - 3 months ago and it was working fine no problems ( windows 8.1 ). Recently the computer has been reborting itself every few hours by it self . I have recently upgraded to windows 10 and I have applications such as Sage, Office apps, Team viewer etc. Here is the link for the desktop I have : http://shop.lenovo.com/us/en/desktops/lenovo/h-series/h50-intel/ Can anyone please help.

hi danield3,
When the machine restarts, do you get a BSOD (sad face with writings on the screen) then the machine restarts by itself?
If yes, can you try to press the Windows key‌ +X, then select System. On the System Properties, follow this guide on how to Disable automatic restart upon system failure and observe. If you get a BSOD, try to read it using WhoCrashed and post the results here.
If the machine just restarts without any BSOD's, try the following:
1. Press the Windows key‌ +R, type eventvwr and press Enter. On the Event Viewer, navigate to Custom Views > Administrative Events and check if there's any relevant errors when the unit restarts.
- Link to picture
2. Perform a clean boot (this will eliminate any apps. running on the background that might be causing the sudden restart).
3. Run Windows Update to get the latest patch and bug fixes for the OS.
Let me know how it goes.

Lenovo k450 recovery disk

Hello all, please, sorry for my bad English.
I've deleted recovery partitions on my brand new IdeaCentre K450. It will be great if you'll make it and give me a link or something - any help, because i can't find one.
On recovery image, it was Windows 8.1 and pre-installed software which I need very much.
I believe in you, guys.

It's not a problem with getting the 2nd copy recovery media if the drive with Lenovo_Recovery partition is in use and Factory_Recovery Disks application can be launched. The only limitation is m$ license policy.

x220 | i5-2520m | hdd 320 | Intel msata ssd 310 series | 3G GPS | WiFi
Do it well, worse becomes itself

Upgrading a Lenovo H50 Desktop

I tried to upgrade the PSU and failed because the PSU i brought was too large for the case.Can someone tell me what PSU I can buy that will fit and work with this system. The PSU I tried already was a Corsaix CX430. Also I was planning on upgrading the graphics card to a GTX 750Ti. Will this be compatible?

Registering Extended warranty for my IdeaCentre K450

Hello all,
At a loss here to be honest,
I purchased an IdeaCentre K450 Desktop and along with it for piece of mind payed for the 2 year accidental damage warranty, called - 2YR Mail-in/CCR + Accidental Damage Protection.
The computer arrived perfectly fine but when it came to register the warranty, things started to go wrong when it asked for my product number.
In the email i recieved it told me to click the link and register my extended warranty. It asked for a 4 digit number but on the side of my desktop it has a 5 digit number.
Stumped by this i called the helpline which was beyond useless, i kept getting told i was in the wrong department and that i needed to call another number. I got passed on to 4 different people, all of which were fairly rude.
What i did pick up is that yes the warranty does require a 4 digit number and also they kept asking "So you are trying to register the warranty on a ThinkPad?" When i told them it was an IdeaCentre i would then get passed on.
I am feeling very lost and worried that i have purchased a £600 computer that i am completely on my own with if anything goes wrong.
I am wondering if i have been miss-sold the warranty as it seems that the warranty i have purchased isn't for an IdeaCentre even though it popped up as an option when buying it.
Any help/advice would be greatly appreciated as i am at a total loss.
Many thanks,
Pauline

Desktop freezes up

Hi, I have the KSeries 450 desktop and I have been having problems with it. I would turn my computer on and be on it for a little bit when all of a sudden the screen would turn black, freeze up, or turn white. Also when I'm listening to music or watching a video the sound wouldn't work as well. It would make a strange noise like a gliching noise, I believe would explain it. How do I fix this problem for it to stop reaccuring? It happens often. Thank you.

Hi CasmiT,
Welcome to Lenovo Community!
I’m sorry to hear that your K450 Desktop is freezing while playing videos, I suggest you to re-install Chipset, Display & Audio driver from our support website and let me know the findings.
Hope to hear back soon
Best Regards
Shiva Kumar

Lenovo G580 boot menu is not working when pressing F2 and F12 key

QuestionI bought a new Lenovo G580 series laptop. After installation of Windows 7 Ultimate x64 bit edition, a problem revealed when Lenovo driver get installed.
When I installed Intel HD 3000 graphics driver and restarted laptop, the Window was unable to start normally. It displayed an error, so a recovery program started which was recommended. But this program failed to resolve the problem. Later, I tried again to load Windows normally but the blue screen fatal error showed up.
I attempted to reinstall Windows again, but after restarting window, the boot menu was not showing up after pressing F12 key. F2 key was also not working either.
I spoke to a Lenovo techincal assistance expert and they suggested me to remove battery and charger and press start key for 30 seconds.
My problem still remains the same, and I am unable to access boot menu.
The bios version is 62cn34ww. ls there a way I can get this running again?
AnswerPlease take note that the suggestion below is just a troubleshooting guide. If the steps could not fix the issue, you need to send you machine in for service for further assistance.
Try removing the hard disk , then press F2 button to enter BIOS
If you are successful in entering the bios, pleaes load set up defaults
Save setting by pressing F10 and shut the machine down
Connect the hard drive back and check if can enter BIOS via F2 and F12 to see boot menu

How to create recovery disks for Lenovo H530s with WIndows 8.1

Hello there,
I just purchased a Lenovo Hf30s type 10131 with Windows 8.1, mini tower: http://support.lenovo.com/us/en/products/desktops-and-all-in-ones/lenovo-h-series-desktops/lenovo-h5...
I like to create recovery disks, but the already installed program OneKey Recovery does not have the option of recovery disks, it allows only larger media such as USB stick and hard disks.
Here to I have 2 questions:
1. Is there a way to create a recovery disks that will create the original factory settings with 5 partitions?
2. Does any one knows if the recovery siskd sold by Lenovo (for Netherlands they cost between 23 and 38 Euro) would do the job by creating the factory settings with 5 partitions?
My goal is to reformat the hard disk and aprtitionig it the way I need it, but in case of anything, I would like to be able to go back to the original facttory state of the unit, especially if I have a harddisk failure and neer to replace the hard didks.
Thank you in advance and I wish you a very pleasant and successful day.
