Lenovo Flex 4 BIOS Critical Update and Battery issues

Q: Lenovo Flex 4 BIOS Critical Update and Battery issues

Hi Lenovo Forum,I wanted to ask for help and advice on whether there is a need for my Flex 4 laptop to update its BIOS.It's my first time opening the Lenovo companion app that came with the laptop and I noticed that there is one critical update. Here is the installation history: Here is the system info from the companion app Now my question is, do I have to update this or simply ignore it?Just to clarify, I'm not really a tech savvy person. I am unsure if this is safe or not. I read from other sites that updating the BIOS may have risks of bricking the laptop and make it unusable. So, I really need help if I should proceed with the update or leave as it is. The current situation right now is, everything seems to be working fine. I am near my warranty expiration. The only complaints that I have is that whenever I leave my laptop and set it to sleep by 11PM, I open it the next morning and the battery is all drained to 1%. This does not happen all the time, but for it may happen quite frequently. Here is my battery information And one other complain is that, even if I set it to sleep mode, sometimes, I do hear the laptop fan go really loud. I am also not sure why that happens. But I hope all my additional information would be helpful on determining if my computer has issues and if I do really need to update the BIOS. Any type of help would be appreciated. Thanks!

EDIT Upon checking this link:http://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/flex-series/flex-4-1570/80sb/80sb000... It seems like I have dozens of things to update that doesn't even show in the Lenovo Companion App.Most importantly, this has the latest BIOS:BIOS Update for Windows 7 (32-bit, 64-bit), Windows 10 (32-bit, 64-bit) - Notebook0VCN25WW(V1.09) I am not sure what is the necessary version or required updates.

My Flex 14 1480 is a week and a half old when the system update application prompted me to update my BIOS. As i recall it wanted to update my bios from 1.04 to 2.0 I clicked yes, and the bios update ran and initiated a restart of the computer. Unfortuatnply now my computer does not start up and i am greeted to LEDS being on but a black screen without a lenovo logo.  I then tried to go on the Lenovo website and for the bios version that i just installed, there is no 2.0 version listed, specifically 2SCN20WW. There are no bios updates period. Was this update pulled, and if so what can I do to recover it so it boots again.  http://support.lenovo.com/us/en/products/Laptops-and-netbooks/Flex-Series/flex-4-1480?tabName=Downlo...  thanks

I have a Flex 4 1480 Signature Edition ideapad 80VD0007US and I'm trying to update the BIOS via the System Update utility.  When I choose to install the suggested update for the BIOS I get a message stating that this BIOS is only for "510S14IKB 310S15IKB YOGA 510-14IKB YOGA 510-15IKB" - none of which is my machine I'm pretty sure.  What can one do to find the correct BIOS and update it if the System Update utility doesn't give you the correct one?
 
The Lenovo Settings utility says that my BIOS is currently: 2SCN23WWV2.03

A:Flex 4 1480 - Incorrect BIOS in Lenovo System Update utility

Welcome to the Lenovo Community !
 
Sorry to hear of the difficulties you are experiencing.  The warning message you are receiving during the update is partially correct.  Your model should have been included in that warning since that BIOS update covers all the models listed.   Here is a full description from the BIOS update's README file....
 
Flash BIOS update - Flash from Operating System version for ideapad 510S-14IKB, 310S-14IKB, 310S-15IKB, Yoga 510-14IKB, Yoga 510-15IKB, Flex 4-1480, Flex 4-1580Version 2SCN25WW(V2.05)Applicable OS Win10
 
I would try the upgrade again and click to proceed.  Otherwise here is a direct download link to that BIOS upgrade from the Lenovo Download Library for your model....

My wife's Flex 14 stopped charging. I am thinking that battery is old and need replacement (I hope), but when I look on the Lenovo site, I do not see the battery. I tried contacting Lenovo, who argued with me that the battery is sealed (wrong), but finally send me to Emcompass parts. They looked up the serial number and was able to correctly identify the computer, but could not find the part number for the battery. They then transfer me to Geek Squad for some reason. I did see a few battery on sale at Amazon, but they appear to be greatly smaller in capacity (2200 instead of 3560 ma). Anyone know how I can order the higher capacity battery or at least locate the actual part number ? Is this normal, I never had issue getting batteries for my Dells. Paul

I bought my flex 3 14" just over a year ago. A few month before my warranty expired, the battery stopped working. It would not charge past 0%. I had to have it pulgged in in order to be able to use it, but as soon as I unplugged it, it would die. I sent the computer into the lenovo shop to be repaired, and when it came back the battery was working... for 24 hours. Now my computer has trouble charging up. It stays at it's current battery level. Also, it will charge for half a second, not charge, charge, not charge. This causes my brightness to go up and down. Unfortunately, my warranty has expired, so I can't send it again (idk if you even can do that). The only thing that I could think of that might be causing this is some damage to the wire. Right where the wire leaves the AC adapter and heads towards the laptops there is some fraying in the rubber casing around the wire and I can feel the wire itself. I don't want to buy a new charge just to find that the charger wasn't the problem. Please help.

A:Lenovo flex 3 14" battery problems

Hello Finn3Thanks for using the Lenovo forums.Are you able to try to charge with an alternate charger, sounds like it might be just a faulty charger at this point.
 
Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.(If the battery is internal, please just skip the remove/replace battery steps.)1. Turn the unit off2. Remove the battery and the Mains adapter3. Press and hold the front power button for 30 seconds4. Replace the battery and the Mains adapter5. Turn the unit on as normal

I have a Lenovo Flex 2-15. It operates with or without the AC adaptor being plugged in, so I am quite sure it does have a battery. I could not determine how to display a battery level indicator or icon which is a common feature on most laptops. I just couldn't find such a thing on this machine. I loaded an app called "Lenovo Settings" (version 3.111.0.0). When I click on the Power Status tab, I see a battery icon with three dashes, a status messages "No battery Installed", and "AC adaptor is attached".  [ When I unplug the adaptor, it still says it is attached! ] So, several questions:   - Does this "Lenovo Settings" app really do anything? Is it compatible with the Flex 2-15?   - How do I see the battery status?   - Did I accidentally uninstall a utility? Thanks for all the help in advance.

Hello, I have a much-beloved Flex 3 maybe 10 months old.First question: The battery says it's charging, but it's not actually charging. I"m guessing the battery's shot? I don't have the tools to open the thing up and try disconnecting the battery yet. Second question: Assuming it's dead, is there any problem with runnning the laptop just on the power adaptor? I did see that for other models this seems to be ok. I'm outside the US right now and have little hope of getting a new battery until July. Every day the battery decreases 1%, and eventually it'll be gone. I can wait until I get back if I can run on a dead battery. Currently at 57%.In case it's relevant, I'm in West Africa in 220V land.(As a side note, I dropped the thing when I first arrived and the screen cracked, but it hasn't lost any functionality so far, so kudos to Lenovo for that!) Thanks in advance for any help or advice. I do appreciate it.

Can you replace the battery yourself (when the time comes) on Lenovo Flex 5 15"?  I just purchased mine from Costco.  I owned my previous laptop for many years and was able to replace the battery several times over the lifetime of the laptop.  Just wanted to make sure that was possible with this one.  Are there any instruction out there (ie. youtube) on how to do this?  I could not find a source for the battery (possibly because this PC is new).  Anyone know of a source?

Hi, I recently bought a Lenovo Flex 5 from Costco in the summer of 2017 right before college. Since then, for a while now, it has a couple key issues. 1. My battery life is basically <2 hours on low power mode and 90% brightness, I basically always have to keep my laptop plugged in to use it.2. The fan on my laptop spins randomly and frequently and I don't think I have any high demanding applications running.3. Randomly while typing, the computer will spazz out and flash a lot and switch into and out of tablet mode. Sometimes it gets stuck in tablet mode and I have to figure out ways to go back to normal mode. Are these issues common in this laptop or do I have a defective model? What should I go about doing? Thanks!

Hi everyone. I recently purchased a Lenovo IdeaPad Flex 2 14 for school and general purposes. In general I really like it, but I have noticed that the battery life is not like the 9h (or was it 6h?) that were advertised. I am getting around 2,5-3,5h of battery life, while I'm doing some light tasks like surfing the web. I should also note that this is with power saving mode on. Have I gotten a bad battery or is this basically what I can expect with this product?  You can see the specs in this link: http://www.prisjakt.nu/produkt.php?e=3019464

Have had a Flex 5 1470 for 2 weeks and today for several hours I ran into this issue where whether it was connected to power or working on battery power I could use the laptop only for around 3-4 minutes before it woud unexpectatly shut off (literally an immediate BLACK screen). I could then power it back on and continue to work for another 3-4 minutes before this would happen again. I downloaded a CPU thermometer and heating was not the issue (was operating well below the operating temperature for the i7).  Any ideas of what was going on? What might have caused this issue and more importantly how to resolve this issue? Your feedback is appreciated!

Hey guys, I'm at wits end here. Last week my Flex 3 wouldn't wake up from sleep mode. Eventually the red battery light would come on and when it was plugged in the keyboard would light up and then die repeatedly. After having it looked at and following the steps nothing could be done. I spoke with Customer Service and they sent me the box to send it back to them as it's under warranty. They advised I should have my hard drive backed up before doing so as they can't guarantee anything. After putting the hard drive into an enclosure nothing was happening. The hard drive is mesed up too. So now it looks likeIneed to take it in for data recovery and pay to get the files back. Is there anything I can do about this? I know the files aren't under warranty and the hard drive is. The fact that it crashed after only 5 months of use really sucks. I can't even reach customer service, they keep either transferring me or hanging up. There must be something I can do here.

Hi, I've had this problem ever since the computer came out of the box about a year ago. Hasn't bothered me too much, but I'd finally like to see it fixed. What happens is that at random times during my computer use, a "Battery at critical low level" dialog box will pop up for a few seconds then disappear. I haven't found a pattern to it, sometimes it'll happen twice within five minutes, sometimes not at all during my session. It doesn't seem correlated with battery percentage either as I've had it hppen a various battery levels. It is not like the "Your battery is low (10%)" dialog. The pop up doesn't show a battery percentage, it only says that it is at a critical level. Any ideas how I can get the problem to go away?  Thanks!

Hello,
A week or two ago, I started seeing a pop-up appear on my Inspiron screen (I run Windows 8). The pop-up said that the AC adapter was not recognized, and therefore, the battery would not charge. It was the same 65W adapter that came with the laptop. I hit F2 at startup to check the BIOS, and it said the adapter wasn't recognized. I decided to order a new adapter. While I waited for it to arrive, the battery gradually drained down, but the laptop continued to work while plugged in.
The new adapter came today, an official Dell adapter. I plugged it in... Same error message. Adapter not recognized.
I ran a check on the battery; the system says the battery is fine. I pulled the battery, and the laptop still worked via the adapter. I jiggled and checked all the connections. Couldn't find an issue and couldn't make it work.
I checked the BIOS version and date, and it's from 2013. Time for an update! I downloaded the latest version, but here's the problem: It won't install without the battery sitting at at least a 10% charge. The battery, of course, won't charge with either adapter (it's reading at 1% now). So I can't update the BIOS without some battery life, but I can't make it recognize the adapter and charge the battery without the updated BIOS (assuming that's even the problem, but I'm hopeful that's all it is).
If anyone has any suggestions for how I might make this work, I would very much appreciate it! Thank you!!!

A:Catch-22: No BIOS updated without battery, no battery life without BIOS update...

Please list Dell model number and version of windows. Ex: Dell Inspiron 3543, windows 10
If you don't know, type msinfo32 onto the search box, and then look for System model.....
In the meantime, please check the USB port, where the AC adapter is plugged into system, is loose. You could also wiggle the Adapter's end while checking it in the BIOS to see if the Adapter's type appears.

I recently purchased a new Pioneer DDJ SB2 DJ controller. Upon downloading the neccessary software and firmware from Serato DJ and Pioneer, I connected my controller to my computer via usb cord provided by Pioneer. However, when I opened Serato to start playing around, a error message came up saying that my hardware was disconnected. I looked up support from Serato as I thought it was a software issue. I quickly realized it wasn't after going through all the troubleshooting steps they provided. I then asked my friend to try out the program on his computer (MacBook), to see if it was a software issue or a computer problem. As expected it instantly worked on his laptop without any issues. I determined it was a problem with my computer. I took it to Geek Squad so they could have a look. Unable to fix it, they believe its a Windows 10 issue. So now I am coming to Lenovo to see if they can fix this problem. I find it ridiculous that out of nowhere my computer can no longer detect a usb plug in from my iPhone, external harddrive, and DJ controller.  Has anybody else had these issues?Specs: Windows 10Version 1607Intel Core i78.00GB RAM64-bit operating system

I purchased a Lenovo Flex 4 1480 about a month ago and just recently made the transition from my old laptop. I love this laptop but I am encountering some speed issues with it. Some apps are taking a while to load, but what is the most frustrating is using the web. Web pages on all browsers are taking somewhere between 8-10 seconds to load, and with this machine running a Core i7 7500U processor with 8 GBs of ram, I know this is not right (my old laptop loads pages much faster than this!!!).  I was wondering if this is just some driver problem or I should bring it back to where I bought it since it is still under warranty. Any input would be great!

Hi there, Yuvaraj ?
 
Thank you for writing in to the Lenovo Forum - happy to have you here today.
 

Power down the machine, remove the AC adapter and battery.
Hold the power button for 30secs and reconnect the AC adapter only then turn the computer ON.

If the machine still doesn't power up normally and boot into Windows then it's likely that something went wrong (could be a bad BIOS flash or an internal component might have gone defective during or after the BIOS update).
Also, check the cable to the SSD and the system board.
 
Last resort would be, issue with motherboard. I would recommend you to contact Lenovo service center and report your findings. For more details, Schedule a Call-back for faster support.
 
Update us how it goes.

Hello Lenovo Community!  I purchased a Lenovo Flex 2 14" Laptop last Saturday (6th of September 2014) and I noticed when using it at night time that there was a yellow tint coming from all corners. This yellow tint isn't really noticeable when on standard applications with a bright colour but when watching films or viewing dark images it is really noticeable. I returned the laptop to the store (PC World) and they happily provided me with a replacement, however the same problem is happening with the replacement which I got today. I have included a picture below which shows the tint when streaming a film on Netflix, as you can see it is really noticeable and not something I have seen with any other Laptops I have purchased. The same yellow tint appears on dark images or applications, not just on Netflix.  Has anyone else expierenced a problem like this before? Is this expected? Or have I just been extremely unlucky with the two laptops I have been given? Thanks for any support/advice, Shane

I guess the title says it all. I have tried to change boot mode and priority into legacy, but it didn't work. And i can't really find the diagnostic option, only Normal boot, Boot setup, Boot menu and Recovery.

The BIOS update went smoothly. But with the new BIOS version, no operating system is loaded. The Windows installation hangs in the "Starting windows" stage. Different Linux distributions are also not possible to install and also to boot into Live CD mode. The BIOS switched various modes, AHCI \ Compatible, Legasy \ UEFI. I tried different options.How can I now restore the old BIOS version?

When running Windows 10 Update on a 6 month old Flex 4-1580, a Lenovo Firmware update momentarily appears in the list of updates, but then disappears. When I run Lenovo Update, there is a BIOS update available. When I run that, I get a message: "This BIOS is only for Lenovo IdeaPad, 510S14IKB 310S15IKB, YOGA 510-141IKB 510-15IKB. Do you want to continue?" If I look on Lenovo Support for my system, there is a BIOS update for the Flex 4-1580 indicating a security fix. This is very confusing. What am I to believe? Is the BIOS update available via Lenovo Update valid or should I do a direct download from Lenovo support? JohnD

Hello, My parents have owned a Lenovo laptop for a couple of years now. However, recently this issue showed up and I wondered whether there is a chance there is a solution to this problem which I could try myself, since the laptop its warranty already expired. If I recall correctly, the model of the laptop is the Lenovo IdeaPad Flex 2, running Windows 10. So here is the issue; the laptop has issues turning on. Oddly enough, it is not a very consistent issue. Eventually, the laptop does turn on. The problem is that this sometimes takes hours, other times the laptop appears to be able to boot instantly as it normally would. I have no idea what affects this. When pressing the power button, the keyboard backlight starts flashing. It does this until the laptop completely boots, and as I said, the amount of time this takes varies. I already tried looking for solutions on different forums, but they usually concern the issue where the keyboard backlight flashed and the laptop simply will not boot at all, which is not the case here, as it eventually does but often it takes a while.Other solutions suggested a certain amount of flashes meant a certain issue or failure. Problem here is that the amount of flashes seem to be random, so it is not as if it just keeps looping a certain amount of flashes as it varies. This leaves me puzzled as to what could be the culprit. I am not sure what to do, especially since I have not owned a Windows-based machine in a whi... Read more

Hello! I am new to Lenovo and picked up my 1st laptop yesterday when my HP died. I have always had HP and grew tired of how easy they break & poor battery life, so I wanted to try a different band. I love the computer, the keyboard, track pad & screen are amazing. I bought the ideapad 320-15IAP for about $330 (Including tax) The specs at the store advertised 4.5-5 Hours of battery life, but I have not been able to get a charge better than 2 hours. For someone that uses my laptop at work and on the go, this will not do. Can any one offer up any advice? Does lenovo sell stronger batteries for ideapad that I can replace with this current battery?  My next issue is the Windows 10 update that you are forced to do, I have been trying to install it since 9PM last night, it is now 9PM tonight, a full 24 hours, and it has not fully installed. I have done my fair share of google searches and many people have had these same issues too, but no good solutions outside of deep computer hacking, I don't want to have to do that on a brand new computer. Thanks for any and all help!
