Lenovo C series 200

I recently upgrade my hard drive and installed Windows 7 professional, I noticed that on power up the Hard disc drive indicator and the Wireless LAN card indicator extinguish but the LCD ON/OFF indicator remains on together with a blank screen. When I select the LCD on/off switch to on the screen comes alive. This function did not happen when I had my old drive installed and the previous windows OS.
It seems as thought the LCD ON/OFF indicator has been reversed, is it a BIOS problem and if so does anyone know how to fit this as it is so annoying having to do this all the time.Thanks

hi rayb719,
It's possible that there's an issue with the power switch board (this is an internal part that controls the unit when it turns ON). It's probably just a coinsidence that the part suddenly started to get defective after you upgraded HDD.
There's a cable connected to this part. Try to re-seat it (see page 42 - function board on the hardware maintenance manual) If this doesn't work, you may need to contact lenovo no how to go about replacing this part.
Power Switch Board:
Hope this helps

  • Lenovo 3000H series Desktop Motherboard

    Dear Members.Could anyone of the forum member help me to get a good working condition Lenovo 3000H series Desktop Motherboard?Please offer your price.Thanks!

    Think there is really nothing you could do. Mine is also faulty. I changed the internal battery of the m/board and the bios set up continuously asked me to press F1 to enter setup or F2 to resume. Worst, it getting from bad to worst, the power supply seems to be giving trouble too. I am a seasoned guy who used to build desktop from scrap and i have one that is based on 486 which is still working today. Inspite of its fame(ie IBM) lenovo's m/board doesn't seem to be so lasting afterall.

  • Lenovo X201 Series Tablet/Laptop

    Hi I recently bought a Lenovo X201 Series Laptop but the screen is cracked it has a touchscreen interface I would like to know can I replace the touchscreen with a 12.1inch LED or LCD Screen as I dont want to spend to much on a touch screen details of laptop is below
    Product ID: 2985DMG
    Specs:
    Corei7 CPU,500GB Hard Drive 4GB Ram 12.1inch Touch screen.

    Hi,
    there is a lot matrices are installed into x201t. Models also depend of the backlight type - LED or CCFL. I'm not sure whether any supported matrices models are compatible with your laptop. Also there are different LCD cable assembly and LCD rear cover assembly depending of the backlight type.
    To ensure what matrice you have and what's compatible check out on Lenovo' site parts list of your laptop by its [laptop] serial number. Support site doesn't answer a question by MTM only.
    I think it's impossible to fit non touch matrice into the tablet because of the different size (width). Compare the width of x201 and x201t.
    UPD
    Service parts DB says your laptop has 12.1-in. WXGA LCD panel, LED backlight (300-nit LCD), FRU 45N6092 or 45N5388.

    manu, welcome to the forum,

  • Predictions: When will Lenovo X-series support 802.11ac ?

    When do you predict we will see a Lenovo X-series laptop introduced that supports 802.11ac ?
    FYI - 2 sites I read for reliable tech info, including home networking:
    http://www.anandtech.com/show/7127/the-joys-of-80211ac-wifi
    http://www.smallnetbuilder.com/wireless/wireless-reviews
    I'm getting 375-405 mbps by hanging this orb
    ASUS Dual-Band Wireless-N900 USB Network Adapter
    http://amzn.to/14ql6WG
    off my downstairs Thinkpad's USB port .
    That orb pairs with an ASUS RT-N66U Dual-Band Wireless-N900 upstairs.
    On the downside, it's something permanently plugged into my USB port. 
    On the upside, with a USB cord extender, it easily stays put on the laptop coffee table.  And I like the idea of the antenna being further away from my brain.  Most importantly, the performance is compelling. (it seems to be twice as fast as before)

    Any Lenovo laptop with mini PCI-E port should support 802.11ac as long as there's no whitelist in the BIOS. I could've put the Intel Dual Band Wireless-AC 7260 on my Y470, but instead I chose the Intel Dual Band Wireless-N 7260 since the Wireless-AC version has a bluetooth integrated which conflicts with my Broadcom bluetooth that came with the laptop. The Wireless-AC itself works, but both my Broadcom bluetooth and Intel's bluetooth won't work (they both show an yellow triangle with exclamation point on Device manager). The Wireless-N version has no bluetooth so the built-in Broadcom bluetooth works fully.

  • Bluetooth Freezing up on Lenovo T Series Computers

    Lenovo T Series Community
    I own three Lenovo Laptops (T400-Win 7 x86, T430-WIn 7 x64 and T520-Win7 x64) and I have problems with the Bluetooth locking or Freezing up. Its more prevalent on my T430 system than the other two although it happens with them occasionally too.  Typical I have issue when booting up my T430.  The booth tooth never seems to load.  I simply select the Fn +F5 key and re-boot the Bluetooth and I'm off.  With the T520 and T400 the problem usual occurs while using the computer.  Happen 2 - 3 times a week. Again, all I have to do is select the Fn+F5 key and re-boot the Bluetooth radio and typically have no further issues.  Any suggestions about what maybe going on.

  • Battery Maximizer Lenovo 3000 Series

    I would like why no Battery Maximizer software for 3000 Series systems/notebooks?
    Why only for ThinkPad series?

    I tried but it says "cannot install on this system"
    whats more interesting? the lenovo training website says you need to use the battery maximizer software to get maximum battery time.
    So I ask where is battery maximizer software for N100 3000?

  • Lenovo Z Series Z50-75

    Bought the Laptop today. And registered it. But could not register the date I got the computer. It only shows the date it was manufactured. And for me that means om loosing nearly alot of time of my warranty. Also not possible to update Windows 8.1 from Windows update. Nothing wrong with my internet. Since it works with all my other appliances. Not sure what to do with this. Since I have to wait all to Monday to bee able to call support. I also found out that its not possible to even email support in Norway, for some reason.
    Solved!
    Go to Solution.

    Welcome to the Lenovo Community !
    Sounds like you purchase your laptop from a retailer other than Lenovo.  In those types of sales the warranty date starts on the day the retailer purchased their shipment from Lenovo.  Generally Lenovo will add an additional month to the warranty to make up for the time the computer may have sat in a warehouse or on the store's shelf unsold.  With your purchase it sounds like it sat longer than expected.  Not a problem.  Use my link below to update your warranty purchase date.  Choose the Americas as the Region and submit.  On the next page will be a web form.  Choose Inform Machine Purchase Date and fill in the form.  You can then attach a scan of your receipt and submit it to Lenovo.  Your warranty period will then be updated with the new date.

  • Lenovo S10 Series Black Netbook

    My question is when you order the S10 in black does that mean the keyboard is black.  My Son's friend stated that it's black on the outside but the keyboard is white.
    Also I wanted to thank Mark the Admin here for resolving the battery replacement question on my other Son's Y510.  I apologize for a well over due thank you and we are all one big happy Lenovo family.  Thanks again Mark for the extra effort!
    Best regards,

    He might be thinking of the pre-release version that appeared on the web.  The current versiobn is ll black, including the keyboard.

  • Lenovo G series : Drivers are not instatling on XP OS

    Hi,
    In G series, model 41514BQ, I installed XP OS. When installing Audio dirvies, getting a message that not compatable with XP. The drivers not passed Windows XP Logo signature. I tried for drivers in Lenovo site. But my model is not available in the site. How to install audio drivers in XP OS?
    Regards,
    Dhanunjaya Reddy.

    I have struggled with the same thing, until about 1/2 hour ago....And its real simple.  I'm not a techy but here's what worked for me. 
    Since Lenovo doesn't send boot discs you are going to have to create one.  I went to http://www.ntfs.com/boot-disk.htm and downloaded the trial version - good for 10 days.  If this works for you then you should buy the software (that goes w/o saying).
    Once loaded to your machine you will need to create a DVD (CD may work as well, all I had was DVD's handy).  Just lauch the application and it will do this for you. 
    Then you need to insert the DVD/CD into your player and restart the machine.  
    Once lauched the Software will lauch the Active@ Boot Disk menu.  One of the options (going from memory here) was to give you a windows prompt.  I simply typed c: and took me to the C drive.  Then I typed chkdsk /f c:
    I was then told my c drive was locked (sounds familiar I bet) but this time I was given the option to dismount the volume which I did.  And it finally ran chkdsk, found and corrected all errors.  
    I rebooted my machine, launched diskeeper,  and guess what - I can finally defrag my harddrive now which is sorely overdue!
    Good luck.  I hope this works for you! 

  • Trouble when upgrading from android 4.2.1 to android 4.4.2 on Lenovo S920 series

    Dear Lenovo,
    I was using Lenovo smartphone S920 series since January,2014 until now. When November 2014, I Got notification from Lenovo trough OTA system update for upgrade my Lenovo android from 4.2.1 version to 4.4.2 version. In my first 3 month using my Lenovo S920 with new OS android 4.4.2 kit Kat, nothing happen with my Lenovo smartphone. Until in the middle of February 2015, my smartphone became trouble. The device is getting overheating, 3G signal is wasn't detected in 1st slot simcard, but when I was change into 2G mode the signal is detected and the device is wasn't overheating.
    On that time I was decided for bring me smartphone to the lenovo authorized service center to fixed it. When I was coming the technician officer was explained me that the trouble was caused by OS upgrading. And should be downgrade back to the 4.2.1 jelly bean version,because the 4.4.2 kit Kat version from OTA Lenovo is doesn't stable and caused the damaged on 1st 3G SIMCARD slot. Honest I felt curious,why Lenovo sent Over The Air to upgrading the OS if that isn't stable. On that time the technician officer at Lenovo service center decided to change my smartphone platform machine with a new one, and of course with e new IMEI serial number.
    From my bit explanation above, I need a favour from Lenovo team the answer my of question below :
    1. Is that true if the damaged was caused by the unstable kitkat OS which sent by Lenovo over the air? And why?
    2. After the service center was change my Lenovo S920 machine with a new one, since April 2015 later, now I was back receiving a notification from Lenovo for upgrading the OS from 4.2.1 to 4.4.2 version, I was receiving the notification almost 10 times since the service center fixed my lenovo. Is that save if I'm back upgrade the OS as Lenovo sent me the notification?
    I am living in the Indonesia country.
    I need a favour for Lenovo team give me the explanation of my question above.
    Thank you,
    Warm regard.

    Hi,
    I have seen this problem.
    I assume that Apex 4 do not give fxx name to items anymore in order where columns are in query.
    This is one of reasons why we have not been yet able to upgrade.
    And it seems this same problem exists in Apex 4.1 on apex.oracle.com
