Lenovo G400 additional RAM installation

I have a LENOVO G400 laptop and added additional 2GB RAM from my previous ACER laptop. Aftern placing the RAM and turning on the power, my laptop screen display is blank. I dont see anything. But when i remove the RAM that I added, my laptop works fine. What seems to be the problem? Why wont it display anything when I add the 2GB RAM? Can anyone help me?

Hi gerardReeve,
welcome to the forums,
Maybe this is an incompatible RAM ? are you sure this 2gb ram stick is a DDR3 ?

Additional Ram Installation?

I bought the MacPro with 2 GB installed on 4 512 sticks, one pair up on riser A, the second pair on riser B.
I installed 2 additional GB's, as one pair as follows:
Riser A/DIMM 1 512 MB
Riser A/DIMM 2 512 MB
Riser A/DIMM 3 512 MB
Riser A/DIMM 4 512 MB
Riser B/DIMM 1 1 GB
Riser B/DIMM 2 1 GB
So is this optimal, as the heat seems pretty high in A1 most of the time, ~70C?

I have the same RAM as you have. I know that Apple suggest filling A1, A2, then B1, B2 Then A3, A4... Exactly as you did.
There's a site that suggest otherwise:
http://peloche.smugmug.com/photos/91752872-O.jpg
So my config is 4B. You can try it. The riser A has a higher temperature so if you put the 2 X 1Gig in riser A, the the cooling is easier since there is only 2 chips, letting more air go thru.

Unable to boot new Linux installation on Lenovo G400

I am having problems installing Linux Mint 16 to a Lenovo G400 that I recently purchased here in China. I have an older Lenovo that I have had for several years, and have been quite pleased with it so I thought I would get another. I gave up on Windows several years ago, and have been running exclusively Linux, mostly Ubuntu or Mint, ever since. I have heard and read things about how Microsoft seems to be fighting back to restrict the spread of Linux, so I took a Live USB stick of Linux Mint 16 so I could see if start it with any machine that I was interested in.
The machine I tested my USB stick on worked fine, so I sent them to the warehouse to get a fresh one in a box. My problems started when they came back from the warehouse with another model, newer, with a faster processor, and pre-installed Linux. I entered the data required to complete the setup, and played around with the Linpus OS a bit before deciding to take that machine instead of the other. My thinking was that I could replace Linpus with Mint later. I did not try booting from my USB stick before agreeing to take this machine.
Later, after trying out Linpus and deciding I had a strong preference for a Debian derivative, I had trouble setting the boot order, but resolved that by finding a copy of the user guide in English. When I tried to boot from the USB, the first thing I noticed was that anything I tried to run from a Live USB stick would not function in standard or default mode. The menu would come up, I would select the default or standard mode, and the system would start to load but a few seconds later the screen would go black. The USB continued to flash for a while but the screen stays black.
At first I noticed this problem with Gparted, which would not run in default or failsafe mode, but does run in safe graphic mode. Similarly, with Mint 16, the live USB will only start in compatibility mode. Later there were several other live systems that I have tried with similar results. Almost all of the live systems I tried ran in their equivalent of the compatibility mode. The one exception to that was Boot-Repair-Disk, which I could not get to work at all in the 64-Bit edition. The 32-Bit edition did work, in their equivalent of compatibility mode, but it told me I needed the 64-Bit Edition because EFI was detected.
When I succeeded in getting the Gparted and Mint 16 live USBs to function in non-default modes I decided to go ahead with my repartitioning and installation plans. This may have been my second mistake. Maybe I should have taken this machine back, but I didn't.
With my Live USB of Gparted running in Safe Graphic mode, I found 6 partitions on the HDD: sda1 is FAT 32 and labeled boot; sda2 is an unknown file system and labeled bios_grub. Both of these partitions are 500 Mb, and I left them alone. I also left sda3 untouched, which is labeled linux-swap. Sda4, sda5 and sda6 I re-sized and re-formated to use as two / partitions and a shared /home.
I then installed Mint 16 in sda4 with sda6 as home. I left the GRUB intallation in the default setting, sda. The installation seemed to go alright, but when I try to boot I just see Lenovo and then the screen goes black. It does seem like the system may be loading and I just can't see it, but that is only a guess. I don't see anything that looks like the GRUB screen and so there is no way to use compatibility mode. Using Gparted from a Live USB suggests that the installation worked and there are files there.
I have searched on the web and have been unable to find anything that helps. Obviously, I am not an expert, but I have installed Linux quite a few times and never experienced anything like this. But then I am used to starting from a clean disk.
I am very tempted to delete the two partitions that I left in place and try an installation like I am used to doing. But I do not know anything about EFI, and my hard drive is listed in BIOS setup as an EFI HDD Device, so I don't know if my machine would still work if I delete these partitions.
So I am very much in need of some advice on this and I wonder if anyone can please offer me some guidance. And perhaps I should add a few more details, such as: USB Legacy is enabled; Boot Mode is set at Legacy Support ; Boot Priority is Legacy First ; USB Boot is Enabled; and my BIOS Version is 78CN25WW(V2.03).
I am sorry to go on so long, but I have tried to be thorough, thank you.

Hi, the W520 has ACPI and powermanegement issues on kernels < 2.6.39 without specific patches. Two questions:
What version of (K)Ubuntu are you trying to run?
What is the setting of your graphics system in the BIOS? Most of the time, setting it to Integrated just works fine, the open source Intel driver is quite good. When setting it to Discrete, you can either use the open source Nouveau drivers for the Nvidia card or the Nvidia proprietary binary drivers, all with varying success. At the moment I would not recommend setting it to Optimus, since support with Bumblebee is work in progress and quite tricky to handle. I am not sure what the Live CD is trying to do, but test it with graphics set to integrated first. Because of all the manual tweaking necessary two month ago I switched from Ubuntu to Gentoo, rolled a new kernel and never looked back. See my thread about HowTo Running Linux on the W520:

Cannot Access the Service Partition after installing Lenovo Driver and Application Installation

I recently upgraded my Lenovo 3000 H210, M/T 5355-2NU from Windows Vista Home Premium (64-bit) to Windows 7 Home Premium (64-bit) with the media received through the Windows 7 Home Premium Upgrade Fulfillment Program.
I installed the 64-bit version of the Common Components Installation v1.0.0.8 and restarted the computer and then installed the 64-bit version of the Lenovo Driver and Application Installation program, v5.1.0.0900. After
restarting the computer, I receive a message box stating "Cannot access the Service Partition". If I click on
Lenovo Driver and Application Installation on the Start Menu, I receive an error that the installation has not
completed. Restart to complete the installation. If I restart the computer, I am back to the first error.
Any idea how to resolve this situation?
Any help is greatly appreciated. Thanks in advance.

I am having the exact same problem. It's driving me nuts. I also downloaded and attempted to reinstall the factory software from Lenovo's site. It installs but will not launch, giving me the following error message: "This software is for intallation on a Lenovo computer." Or words to that effect.
Hopefully someone knows the answer. Tried tech support twice. Ugh... Thanks in advance.

T42 not recognizing additional RAM

I had to reformat my hard drive and in process of updating drivers. THe monitor image is very slow and I believe it may be due to the T42 not recognizing the additional RAM I had put in. Is there a way to download a driver for this RAM so it is recognized or another solution? Thanks in advance.

Hi and thanks. The screen is very slow meaning when in internet explorer and scrolling down a web page it sort of almost blurs. I initially though it was RAM but I was mistaken that on this particular T42 i didn't add any but just have the 500mb it came with. But I beleive something is causing the viewing to be slow. I just reformatted the computer so there is no programs running other than what is normal with XP installation. I played with the Display and brought down to 16bits 768 and it still slow on scrolling down any webpages.
The exact model is t42 - 2373 - h12.
I apologize for misdiagnosing but perhaps you might still know what the problem is? Thanks again.

Reinstall Windows 8 in Lenovo G400

Last day I formatted preinstalled Windows 8 laptop(Lenovo G400) and installed linux. Now I am planning back to Windows 8 Is there any way to get my lost preinstalled windows 8 product key ?

Hi vipinbaby,
Thanks for Posting!
The product key in the BIOS is only meant for an OEM OS,
meaning that you cannot use the product key in the BIOS unless the IWndows 8 installer came from lenovo.
I suggest two options,
1. Install a non OEM (Retail) installer of your desired windows version and it will come with a product key purchased from Microsoft.
2. If you cant to use the BIOS Product key, You can call Lenovo Technical Team and ask on how to obtain the Recovery CD. fees may apply.
Hope ths helps
Cheers!

Second internal HD, additional RAM & proper settings for them

Hi guy!
I want to thank you in advance for reading my questions and answering it. It may be long.
Today, I've received my memory upgrade 4GB (2X2) from OWC. And my 2nd hard drive Seagate Baracuda 500GB 7200.
I read all my the instructions and installed all memory and HD myself, all seams to be working, my system shows RAM and HD. However, there are some questions I have unresolved, I called tech support they couldn't tell me more than just "call the HD manufacture and ask them"
1st. After I've installed HD and started the computer, the window came and said that I need to initialize the HD. I clicked "initilialize" it took me to disk ut. I erased HD and gave it a name "Mac HD2" Now, it is showing me that I only have 465.64 GB of space available. It shows that only 108MB is used. Where is the rest? I know that it won't show the whole 500GB, but it ate up 35GB, itsn't that too much? So, my question about this is: Should I be doing something else with this HD? Should I be calling the company that sold HD and have them replce it? Or is it ok to hav such a loss?
2nd. What is the best way to place my folders & files on both HDs. I was thinking to take my Documents/Movies/Music/Pictures folders and just place them on HD2 and keep HD1 for applications only. Is this right?
3rd. My HD1 is 160GB (148.9 as per info.) My Documents/Movies/Music/Pictures folders are about 55Gb my application folder is 8 GB I should have about 86GB left (if we take 148-55-8) I only have 67. What am I missing? The user folder (yuriyork) is 60GB. I'm totally confused with where the space is.
With this said, I'm back to the 2nd question what files/folders I should move to HD2? I just want to do it right to try and up the computer performance.
4th. When I do move files/folders to HD2 should I just open HD1 and HD2 in finder and simply drug and drop folders from one window to another? I think it's not right way of doing it. I think I need to somehow specify to the system that Documents/Movies/Music/Pictures folders are now located on HD2
5th. With increase RAM, should I do any setting on OSX to tell it that there is lots of RAM and that it can use it as much as it wants? Like for example, I know that in Virtual PC I can set up the amount of RAM it uses. So, with that I thought that I may need to specify something like that in some other settings, if so than where?
I hope I didn't confuse you all with some much stuff. To hopefully simplify this, I'm going to put the JPG file on the web for you guy to see what folder are what size and may be give me an idea what is the best way to do it.
Here is the photo:
Again, thank you for taking your time to answer my questions, you guys have always been very helpful.
Thanks to all!!!

#1: The primary reason for the discrepancy is numbering convention. To hard drive manufacturers, a kilobyte is 1,000 bytes, a megabyte is 1,000,000 bytes, and a gigabyte is exactly 1 billion bytes, so 500GB is 500,000,000,000 bytes. Computers, using the binary system, don't use 1,000 to represent a kilobyte; instead they use 1,024.
Therefore, when you divide 500,000,000,000 by 1,024 (KB), again by 1,024 (MB), and again by 1,024 (GB), you'll get 465.66 GB, which is almost exactly what you're seeing.
#2: When I installed a second hard drive in my G5, I moved my Music, Pictures, and Movies folders to this drive. Then, I just had to point iTunes and iPhoto to the new directories. The sidebar links still take me to the original folders on the original drive, but that could likely be fixed if I replace the folders with an alias or symbolic link that pointed to the new location.
#3: Try downloading an app such as Omni DiskSweeper to help locate where all the space has gone to. It'll give you a breakdown by each folder and subfolder on the drive.
#4: As I stated in #2, an alias or symbolic link should work if you want the sidebar links to continue to function after moving the folders. Otherwise, just direct iTunes and iPhoto to the new locations.
#5: OS X manages memory on its own for each application. There's no longer the need to allocate RAM to each app like there was in the pre-OSX days.
When installing additional RAM, it's often recommended to reset the NVRAM to ensure that the computer recognizes all of it properly. To do this, reboot the computer while holding down the Command, Option, O, & F keys. This will boot you into open firmware. At the prompt, type the following (and press return after each one, of course):
reset-nvram
set-defaults
reset-all
The computer should reboot after the final command.

Installing additional RAM into hp s5150t

I have a quad core s5150. I recently tried to add two additional RAM modules. I verified that I had purchased the correct RAM on curcial.com and by speaking with their reps. The computer would not take the RAM in any configuration. We tried seating the new RAM into the old modules one at a time and it still would not work. At last, the crucial rep told me to try and update the BIOS. Hard as I tried, for three hours, I was unable to find the BIOS update on the HP website despite looking where the HP video told me to look. There were lots of update options but no BIOS heading. The auto detect tool could not identify my computer for some reason. The HP Update tool installed with the machine said no updates were available.
I am wondering a few things, 1) Where can I find the BIOS update on the HP site? It is not in the list of updates on this page, where it is supposed to be:
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4063&lc=en&cc=us&dlc=en&sw_lang=&product=4002...
2. Is it possible there is a problem or conflict beacuse the machine shipped with Windows Vista and I updated it to Windows 7? Looking in the BIOS, the last update was May of 2009, long befoe Windows 7 was updated from the old VISTA files.
3. Any other reason you might know for the modules to not be working? We exchagned them for a fresh set already and still the same problem. They are clicking into place. Not sure what to try.

Thanks for your support, Jaco. I appreciate your input.

I have Mac OS X 10.5.8 on mid-2009 Macbook Pro (683MB RAM used, 81.67GB free space), do I need additional RAM to update to Snow Leopard?

I have Mac OS X 10.5.8 on mid-2009 Macbook Pro (683MB RAM used, 81.67GB free space), do I need additional RAM to update to Snow Leopard?
I was told I can update to Snow Leopard without adding RAM but just read on another discussion thread that someone with the same age Macbook Pro that I have was told to purchase more RAM then update to SL.

LENOVO G400 TURN OFF AUTOMATICALLY AND NOT LOAD BIOS SETUP

i have a lenovo g400, once i turn on it only the lenovo name appears in the screen and then it turn off automatically and then turn on and turn off again and so on... also I was having problem that my Lenovo G400 laptop did not display Press F2 to Enter Setup during the boot process, and because of this, no amount of hammering the F2 button would allow access to the BIOS. I attempted all of the standard fixes, pulled the battery, held power down for 30 seconds, removed the HDD -- nothing would cause this to appear. i dont know whats the problem of my laptop..please help me to fix it..

hi PRAY2431,
Welcome to the Lenovo Forums.
Can you try to access the BIOS by pressing the OneKey Recovery button.
- Link to picture
If you manage toget in, try prssing F9 to reload factory defaults then press F10 to save and exit (this should reset the hardware configuration of the machine).
If you still can't get into the BIOS and the machine still turns off after POST (lenovo screen) then there's likely a hardware component that's failing. If you have a spare PC, try to create a Lenovo Bootable USB Diagnostics and boot from it by pressing F12.
Alternatively, you can contact Lenovo (for service) or contact one of the Lenovo Authorized Service centers below

Lenovo G400s Wireless Connection Limited Access on Windows 7 Ultimate - 32 bit

Just bought Lenovo G400s, install windows 7 ultimate - 32 bit on it.
It turns out the wireless network driver need to install manually, the disc driver that came with laptop was for windows 8.1. So I went to lenovo website, put on the series and download the wirelss network driver which is around 250 MB.
I installed the driver and connect to the wireless network. My office wireless was on security and use static ip. I changed the ipv4 ip static already. It connected for a while, 1-2 second then lost connection. I checked with ping to google, got 2 records of live connection which is very short. After that it try to reconnecting itself again and again with status said "Limited Access"
I search in google, read some forums about problem in different series, so I use another computer go to Intel website to download latest driver. Got it installed, but it's still the same.
I try download broadcom driver, but it's really different and doesn't work at all.
Now I don't know what to do.
Windows 7 Ultimate - 32 bit
Inter(R) Centrino(R) Wireless-N 135
Driver Provider: Intel
Driver Date: 1/26/2014
Driver Version: 15.11.0.7
Digital Signer: Microsoft Windows Hardware Compability Publisher
What makes it weird, although from intel website said the driver date is in 3/21/2014, and the version is 16.11.0, but this information I get from device driver was different.
Here's the intel's website if you're wondering:
_https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Wireless+Networking&ProductLine=Intel%C2%AE+Wi-Fi+Products&ProductProduct=Intel%C2%AE+Centrino%C2%AE+Wireless-N+135#&OSVersion=Windows%207%20(32-bit)*&DownloadType=Software%20Applications
Can anyone help me?
Solved!
Go to Solution.

Today I want to install windows 8.1 on it, because the laptop came with windows 8.1 driver disc.
However, I try the wireless connection once again , one final try before I clean install the OS.
It turns out the internet connection is connected. Ping is quite stable, got a small drop. Nonetheless, IT'S CONNECTED!!!
I don't know what happened, I tried thousand ways yesterday and gave up. Today I don't set anything just try connecting with static IP set the ipv4 just like I did yesterday, and it connects without hassle!! is there a pc fairy or what?
The possible way I can think of is the router's internet connection's got restarted since It's a new day at office.
Despite how it solved still mystery to me, I think I mark this thread as Solved.

Additional RAM needed

Trying to load new software, both of which tell me I need 1-2 GB of RAM. Where do I determine how much RAM I have, and can I simply buy and upload additional RAM to this model?
Thanks.

Hi
+"Where do I determine how much RAM I have?"+
Apple Menu > About this Mac.
+"can I simply buy and upload additional RAM to this model?"+
Yes. You buy RAM and physically install it. Depending on the model you may be able to do this yourself with an appropriate screwdriver or pay/get an authorised Apple Technician (or someone else who is capable of doing it) to do it for you. There's no upload involved.

Do I need additional RAM?

Hello to all,
Though I am not presently facing any trouble while editing, yet I am feeling discomfortable seeing the free space remaining on my 8 GB RAM which sometimes drops to less than 500 GB when I have just my internet and FCPX on. Do I have to go in for additional RAM?
Any guidance in this matter is most welcome.
DR.SOMANNA

If it ain't broke, don't fix it.
If everything works to your satisfaction you don't need it.
You may want it, but that's a different matter.
If you decide to get some, buy it from Crucial or Kingston, who provide the highest quality at the lowest prices . . . . just a fraction of the cost of getting it from Apple . . . . . and by "a fraction", I mean a quarter!
