Lenovo G505s BIOS Update

Q: Lenovo G505s BIOS Update

Hello everyone!I have really big issues with my Lenovo G505s laptop.(A8-4500M, 4GB ram, 7640G+8570M, windows 7 professional)I have around 20-25 FPS in every game when my charger is plugged in.When I plug it out, I get around 80-90 FPS boost.I did research in a lot of forum, and for some people helped that they updated the BIOS. I searched for BIOS update,I found it(v3.0), but for Windows 8 & 8.1.Is it compatible with Windows 7?Can I make any damage in my laptop if I install that? Please HELP!

Preferred Solution: Lenovo G505s BIOS Update

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

My laptop has been crashing recently after the fans kick in. I am using the latest BIOS version (3.00) and the laptop is only around 6 months old (but for some reason is out of warranty).The crashes mainly occur during gaming but have also occured during multitasking on the internet.In an attempt to fix the problem i have reset the laptop to factory settings but this didnt help.I have used LSC to run a full hardware scan and no problems turned up.  Any advice/ help with this problem would be much appreciated.Thanks

Hello everyone! I ama new user and i am coming up with this post as I couldn`t find any kind of solution for my problem.Recently I decided to do a reinstallation of my operating system, which also previously was Windows 7 Ultimate (x64). The installation went as usual, and after finishing it I went on to install all the latest drivers from the Lenovo site, for my product. When getting close to installing almost all the drivers i`ve needed, i stumbled upon a new version of the BIOS amnd the drivers and sfotware recommended for my laptop, by the producer. So i proceeded to install the upgrade, restarted the computer when it prompted me to do so, but after the so-called restart the laptop did not boot up as usual. At first it was telling me to not do anything as the BIOS is being flashed and then it was telling me something about some sort of image processing, things that i did not understand at the time (i have never encountered anything like that). After that my screen turned black. I have not done anything for a few couple of minutes as i thought it was supposed to be like that, but then i just force shut it down and unplugged the AC adapter. When trying to boot it all up again, the only thing i got was a black screen and nothing else.After doing a little bit of research it appears that, somehowm i`ve managed to corrupt the bios on my laptop or something, and nothing else would work at this point. I tried to remove the BIOS battery and the ram and then put them all back, trye... Read more

Guys, I've had my Lenovo G505s for pretty much 2 years now. I have a poor battery performace. Recently my charger malfunctions. It won't work till i have placed it at an agle of the charging port, meanwhile if i use another charger from a friend, it works very fine without struggle. Initally, i thought it was my charging port but I'm sure that it's not now. Also, recently my friend swapped his battery for mine (he had 50% charge on his battery), as soon as he put it into my laptop, he saw that it was around 28%. A few minutes after that, the battery died. *One Key Optimizer tells me my battery is weak and needs replacement. Battery capacity is at 42%. My question now is :1. Do i just need a new battery and a charger?? OR2. Could it be from my motherboard? (I'm running the AMD A10 with Radeon gpu) I'd really appreciate suggestions from you guys.  Thanks.

Well here we are again. I've done everything suggested as possible solutions for the laptop problem of not restarting after shutdown. I've cleaned the fan, re-applied thermal paste and run all the tests that are available on the Lenovo Solution Centre. I've checked the temperatures and they are around the 35/39 mark. It's run for several days with just putting it into sleep mode. Finally took the plunge last night and went to shutdown, and, yes, you've guessed it won't start again. Why oh why should this happen?????? I'm now at the point of giving up but I thought I'd post this one more time to see if anyone has any more idea's. Really grateful for ANY response. Kind regards David

Hi there. I've posted a couple of times before about my G505s not starting. I eventually managed to get it started and have used it for the last two weeks. When I've finished I've been using the sleep mode and it's started everytime from sleep. It failed again after using shutdown and so I decided to remove and clean the fan and re-apply the thermal paste as someone had suggested. I've done that and am now back to square one as it won't now start. I'd appreciate any suggestions to try to sort out this problem. Kind regards David

Hidy ho all,

I have a Lenovo G505s I bought in august. Up to this point, its been a great machine. This morning (11/20/2014) I installed some updates from windows update. around 4:30 PM today, I rebooted the machine, because I had an hour break in between classes. During that reboot it tried to install those updates, and it said it failed. After the failure it said it was reverting back to the prior state before the updates were installed.

It then rebooted again. It got to the Lenovo splash screen, and some little white text on the bottom of the screen has said for the past half hour "Updating your system (5%)" with the windows 8 little circle thing spinning around just above it.

I did try restarting it by holding down the power button, but it came right back to this screen.

Google has turned up nothing yet. Has anyone else had this issue? If so, have they (you) been able to fix it?
 

A:Lenovo G505s not booting

I think the quickest way around this issue is to let the OS try to install the updates it might take a while to do so(which is a pain) but I would wait because you don't want to mess up your system you might loose more than the time you will wait

A:lenovo g505s fan problem

Hi Mngabriel,
 
Welcome to Lenovo Community!
 
I?m sorry to hear that your G505s Laptop?s temperature is increasing while playing game. There is no other option to increase the FAN speed, the only way to make the FAN run in good speed is by switching the power plan to ?High Performance? mode and then you can choose fan control modes in your Windows Power Plan settings. Select the power icon in the notification area and click "More power options." Click "Change plan settings," then "Change advanced power settings." In the ?Processor power management? submenu, you will find the "System cooling policy" option, if your laptop is equipped with heat sensors. Selecting "Active" runs your fan more frequently, at lower temperatures; "Passive" leaves the fan off until the laptop reaches a higher temperature. Below is the link for the same:

Hello! I've owned my G505s since August 2014 and it has served faithfully as my school laptop. I do not have any money for a new laptop and I've looked at endless posts and articles, so I'm at my wit's end here. It all started last night, when my hard drive just failed to boot. It told me there was no OS installed, despite Windows 8.1 being installed. I rebooted a couple times and the same message popped up and I checked the BIOS settings. They were all correct. I assumed that my HDD became corrupted or something occurred, so I found a Windows 8 ISO from Microsoft's website and started installing tonight, since I knew the BIOS stored the key and would auto-input. That part was successful. The part that's killing me here, though, is the constant shutdowns now. It started ever since I had to reinstall. At first I just put Windows 10 Tech Preview on it to quickly get some work done since I had the install USB with me, but it shut down randomly there too. Now, during the install of the Windows 8.1 OS, it shuts down at random times and corrupts the installation, forcing me to start over and observe the same shutdown issue all over again. I do not have money to ship it and I'm losing my mind here. I thought Lenovo was good, but I'm seeing others with the same exact problem, and I'm several months away from having enough money for even a cheapo laptop. Can anyone help?Keep in mind that I can't even get past a Windows 8 install and booting a Live USB of Linux is a no-g... Read more

A:Lenovo G505s Randomly Shutting Down

hi Chripallo,
 
Welcome to the Forums.
 
It could just be a coincidence but It's possible that there's a hardware part that's failing inside the machine (e.g., Memory, Overheating GPU) which causes the shutdown issues.
 
Things that you can try:
1. Re-seat the RAM and HDD and try reinstalling Windows.
2. If you have two RAM sticks (e.g., 2x4GB), remove one stick and observe if you can now install Windows.
3. (Optional) Check this article on how to create a bootable USB diagnostics to test the RAM/HDD.
    - Sample image
 
Note:
You will need to set the following options in the BIOS to boot from a  USB
Security Tab:
Secure Boot = Disabled
Exit Tab:
OS Optimized Defaults = Other OS.
Boot Tab:
UEFI = Disabled
Boot Mode = Legacy
 
If the problem remains and you're still not able to install Windows after doing the above steps then I recommend you contact lenovo for warranty service.

UNMOUNTABLE_BOOT_VOLUME

I tried the "Last Known Good Configuration" it doesnt help, i did a full disk check but nothing works for me. So my question is: Is the HDD damaged, or are the sectors bad? Should i replace the HDD or is there a solution for my problem?
Thank you for your answers in advance,

Always a good idea to look at your service manual / maintenance manual for this information before you order parts...Go to the support tab on this site, enter in your specifics then select your computer from the list. One your support page loads, at the bottom you will find a link to documents, choose it and read up on your service manual. It has quite a bit of good information about updating or upgrading parts, including a white list of acceptable replacements and upgrade paths.Good luck.CB

A:Lenovo G505s - question about upgrading RAM memory

Hi subhamzzz , 
 
Welcome to the Lenovo Community Forums.
 
Genral specifications for G505s :
- DDR3 / DDR3L * 2 SODIMM, 1600 MHz.- Dual channel for AMD Richland- Upgradeable to 32 GB Memory with two 16 GB SODIMMs
 
Lenovo recommend RAM listed on the hardware manual (item 16 page 83-84).
Regarding third party reseller options , best to check with specific manufacturer Corsair to match advantages of the higher priced RAM from a cheaper value of their product.
 
This may include heat spreaders , backward compatibility and auto detect speed technology offered in vengeance.
 
Sticking with OEM recommendation is still the best option but do not limit users to their choice as long as those choice works for them. 
 
Hope this help answer your query.

You can try to reset the BIOS default and check if BIOS will detect the harddrive. 
It may be the the harddrive itself is bad , so if you have another harddrive to test it with just to islate if BIOS would detect another harddrive. 
 
Hope you manage to abck up your data , you may slave the harddrive in an enclosure and test it on another pc to diagnose its integrity .

A:Lenovo G505s windows 8, preparing automatic repair then black screen

hi Dlskmalpik,
 
Welcome to the Lenovo Forums.
 
Automatic Repair usually kicks in if there's a problem loading up the files that's required to start Windows. If the repair was interrupted and the screen just goes into a black screen then there's most likely a hardware component that's malfunctioning.
 
To check, try to:
1.Boot into the BIOS by pressing the OneKey Recovery button
  - Link to picture
 
If successful, set the following settings in the BIOS:
 
Security Tab:
Secure Boot = Disabled
 
Boot Tab:
UEFI = Disabled or Legacy
Boot Mode = Legacy
Boot Priority = Legacy First
 
Exit Tab
OS Optimized Defaults = Other OS or Disabled
 
When done, press F10 (or Fn+10) to save and exit and try to boot from your Windows CD (i'm assumming this is a Windows 8 disc).
 
2. If you're successful in booting from the Windows 8 Disc, see Step 1 to Step 2 of this guide on how to proceed in fixing the issue.
 
3. If the problem remains, consider re-instaling Windows by pressing the OneKey Recovery button and choose System Recovery
  - Link to picture
 
In an event that the recovery fails, I recommend you contact lenovo and report the issue as you may need to send the unit for service..

Hi heidihamed  , 
 
 
Welcome to the Community Forums . 
 
On a Windows boot loop , it would be an advantage if it can proceed on windows advance options for repair options. 
Avoid any option for factory recovery since those would delete your files.
 
Initially turn off your pc and remove the battery and charger . 
Press and hold down the power button for 15 seconds and release to drain remaining current. 
Put back the battery and charger and use the Novo key (item5 page 4) to turn it on . 
Choose  BIOS setup and press F9 for loading defaults , F10 to save and exit  
How was it?
 
If the advance options showed up then we can proceed with troubleshoot and system restore that would allow you to just go back to a previous date before the problem with you keeping your files. 
 
You may also create a repair image to help fix it from a different pc with same WIndows version. 
 
 
Final option should be One key recovery  (page27) but this would delete your files so usually best that you try backing your files via harddrive enclosure and attach the harddrive on a different pc . 
Else booting to a rescue media can help with back ups too. 
 
 
Update us how things would go. 
 
 
Regards

bought this recently, and must say that i am pretty pissed. i did installation of windows 7 on it and it worked fine for some 10 days till it got BSOD cause of bad system info and couldnt even load into windows. only solution was to reinstall. i did fresh install and i got BSOD with fresh install after only few days. checked internet for solution and saw that you could select windows 7 os in bios for optimized settings that should prevent BSOD. but no option for windows 7 in bios. only for win 8 and other OS. i thought ok, i will just download latest bios and flash it. but what happened when i downloaded bios (a2cn38ww) from support page?i got this message "your machine does not match with this bios". so does anyone know where i can actually  download correct bios, or how to contact lenovo support so they can tell me where to download bios?

As I said, After upgrading to latest BIOS v3.00 the CPU overheats and computer shutsdown
 
This was not happening with BIOS v1.00. Anyway I would like to try downgrading the BIOS either to v2.xx or back to v1.00. Where can I download the older BIOS?

Hi all, Need help on my Lenovo G40-70 that I've just bought 6 months ago where I accidently bricked the laptop after BIOS update. It seems during the BIOS updating process it when well but after 2nd reboot there's some message on the screen that the BIOS failed to update factory setting and it freeze on the message for quiet sometimes. After a long wait I decided to long press Start button for hard reboot. Then the scary part comes in where it seems the laptop can't longer shows the Lenovo logo & cannot even boot to Windows, just black screen. Hope anyone can help me on this and give some advice on what I'm going to do. I would like to tried myself first before ending up with warranty claim since I'm worried I've brick the warranty due to wrong BIOS update procedure....

A:Lenovo G40-70 Bricked by BIOS Update

hi mahdhir2005,
 
Im sorry to hear that.
 
  I would suggest you call the Lenovo Technical Team regarding the Issue. If it is the BIOS that's causing the issue then there maybe no source or option to have it fixed without they're help or service.
 
  If the BIOS software you downloaded was from a legit Lenovo Site and correct model, then I think It will be ok to Just report them what happened and ask for possible option.
 
Hope this helped
Thanks!
