Lenovo P/Y/Z Series :: IdeaPad Y480 - 0xc0000021a Error On Restart
May 13, 2013
My Ideapad y480 has been having some severe issues lately related to booting. Whenver I try to reboot my computer (which runs Windows 8) I get the Windows 8 version of the BSOD (the frowny face screen). It tells me that my computer has encountered an error and needs to shut down, and it gave me an error code of 0xc0000021a. Sometimes the computer will boot perfectly normally, but around 75% of the time it crashes like this. It seems to always happen after any major changes are made (Windows updates, updates for games, etc.).
The only way for me to get into my computer again is to do a system restore to before any changes were made. If a new restore point is made and any change whatsoever has been made, I often get another error message, and the system restore fails. These problems don't occur 100% of the time, but its very hard to use the computer when I can't update programs or Windows without issues. I looked other places online and a few of the pointed towards the hard drive failing or reinstalling the OS, but I thought I should ask for any less drastic solutions that could work.

Okay so, I got my Lenovo Ideapad Y500 a couple days ago. Liked it and all BUT when I had my mouse connected into the laptop and then turned off the touchpad, it would not turn back on. The only way I could get my touchpad to work again is by restarting the computer, which is pretty frustrating.
I searched this: [URL] .... for ANY drivers/software for the Y500 mousepad and there are none.
FN + F6 toggles the touchpad on and off and I have tried to turn it on and off, with and without the external mouse connected.

I tried to install a new version of Win7 on my ideapad U300s from a usb that set to be a bootable device containing *iso file.
I also set USB as first boot priority in BIOS setting, of course. But when the installation began, I canceled them all and restarted my laptop but found it troubled.
Here is its error report.
From then, I can no longer boot my laptop from USB as well as enter BIOS setting to set back HDD as first boot priority.
Both Enter/ESC make it restart and then turn to this dumb black screen.
I think I should remove the BIOS battery to turn BIOS setting into its default, shouldn't I?

Check device manager for driver issues
Update Drivers

I have a Lenovo g500 with windows 8.0 Suddenly this month the sound started to stop.
This happens when I start the laptop or if it wakes from standby.
The sound is restored only after a restart. I have already tried microsoft solutions and tested all the services that start with windows start.

Took delivery of my brand new y510p yesterday and the last 24 hours have been hell.The PC is incredibly slow, much slower than my three year old XPS 15 from dell.
The laptop won't shut down/restart.. It just goes through shutdown screen then black screen with keyboard monitor fan etc still on.I have done a system recovery back to initial state and am now running windows updates as first port of call but its been stuck on 13 out of 32 update (whilst shutting down) for the past hour and half.

When I "restart" my Y500 using windows 8.0, it takes a minimum of 15 minutes. Sometimes, if I have time to wait, it takes more than one hour. 90% of the time, I restart it using the on/off button. No problems at all using the button, but the software takes a VERY long time or won't restart at all--just the green screen with the word "restart."

The audio in the video is not from the computer. [URL] ....

The issue was in regards to WiFi not working properly on my Lenovo ThinkPad Yoga S1. After a restart my computer's internet (with WiFi on) would work for a few minutes then it would stop. Long story short, I tried various things, and even uninstalled Norton and other software which I thought may have been a culprit but still the same issue. I also used a USB to Ethernet port (since there is no built in Ethernet port in the ThinkPad Yoga) and connected my computer with a cable and disabled the WiFi to see if it was the wireless hardware not working. Unfortunately still the same issue.
Finally I noticed in the Windows Task Manager a process called "Discover.exe". It turned out this was using some noticeable amount of CPU and wondered what this was doing as I hadn't seen that before. I found out that this was a piece of software bundled in with my computer called Lenovo EMC Storage Connector. I'm not sure why it was running but I ended this process.
Suddenly my internet was working again! This time no problems. I uninstalled this software utility to make sure this doesn't cause this issue again.

I've had my Y510p (8GB RAM, DVD Ultrabay option) for a bit more than four months now and it's been working perfectly for most of the time- however, two days ago, while playing a game the computer or the game itself froze. After trying to bring the Task Manager up/kill the game, I decided to restart it- I turned it off, but once it came back on, it had decided to start "Preparing Automatic Repair". After several times unsuccessfully "repairing" (after which again "preparing") it (it had given me an error, something with Srttrail.txt file), I decided to look up and search the Internet for people with a similar/the same problem- none of the methods worked. So, I decided it could've been from software I've installed or similar- I didn't have things THAT important (I haven't made any back-ups, nor a recovery USB), so I made an initial state lenovo recovery using the Novo button.
After several more fixing methods (unsuccessfull again, people suggested getting into the command promt, using the chkdsk command, but it was in a drive called x:, couldn't find other drives/changing from UEFI to Legacy Support in BIOS settings, I changed them, then changed them back to defaults) it started giving me the "IPv4/IPv6 Network 0 (MAC Adress) boot failed" errors and several tries more, now it constantly gives me the "Windows boot Manager boot failed" error, followed by the IPv4/IPv6 ones. after which it takes me to a blank bright-blue screen with my only cursor visible (similar to what it does i I tell it to go to Lenovo recovery menu now). Also, after trying to turn it on (in the current/last state) it gave me the 0xc000000f error. So, what's happening (the HDD is recognized in the BIOS, the laptop itslef hasn't been moved more then four or five time and used properly)? I have no instalation/repair disc with the laptop.

I just got couple of days old Lenovo IdeaPad z50-75, running on AMD FX-7500.First I jsut now noticed that my CPU runs at 1.07 Ghz, before it was always over 2 Ghz or so which was good ... but maybe I touched something some where in powr settings or something and now it stays on 1.07 even when cpu pretty much utilised. I have set power plan to high performance and also Energy manager is set to high performance mode and Conservation mode is on. why it doesn't clock itself up ? I feel that it is slower than before.

In a few days I'll get my IdeaPad U310, and since it comes with 4GB DDR RAM, I'd like to do a upgrade to 8 GB. I understand it only has one slot for RAM, so I'll buy one stick of course, but I don't know if it's the same size as used in a desktop PC, or is it some mini-sized RAM stick?
I also need to know the voltage of it, is it 1.5V or different?

Whenever I try to install the ELAN/Synaptics driver that I download from my laptop's support page I get an error saying: no Appropriate Driver to be installed.I'm on Windows 7 64bit...I've tried tons of drivers and I'm starting to get seriously annoyed. Non of them work all of them throw error messages and I'm getting more and more irritated with the obnoxious tap to click functionality. I don't even need the driver as I need the annoying tap to click disabled and maybe some kind of scrolling functionality would be nice if it's possible.

I recently recieved a y410p ideapad I ordered off the lenova website. However, it won't start up. When I try, it brings me to a blue screen with a sad face that says I need to do an automatic repair. This flashes for about two seconds before disappearing and the screen becomes grey and says "lenovo" and "Starting Automatic Repair". From this the screen goes completly grey, and has nothing on it. The computer stays this way for hours and the fan will continue to run. I've tried the reset button on the side and resetting the laptop, but no matter what I do I end up back at that grey screen.

I purchased this Ideapad Z50-70 laptop two days back. It was DOS based so I had to install Windows 8.1 OS myself. After installing the OS, I installed all the drivers for this laptop.
The display of the laptop is set to Full HD resolution i.e. 1920*1080. However, it doesn't look as sharp and crips as a normal HD display should be. The text and other things looks blurred. Also, the contrast of the screen doesn't seem well. Though the resolution is set to Full HD, I'm not feeling the quality smoothness and sharpness of the full HD display.

I bought the Lenovo Ideapad Z500 and I'm trying to boot from a USB drive in order to install Windows on it. When I start the boot menu I only see the hard-drive, the DVD and the network. I tried to set both UEFI mode and Legacy mode in BIOS but the USB stick does not appear in the menu when I boot. I put the image of windows with Windows 7 USB DVD Download Tool which formats the stick in NTFS mode.
I have the latest BIOS v1.21 and I tried with 2 different USB sticks: one 16GB USB 2.0 Corsair and with a 32GB USB 3.0 ADATA both on USB 3.0 and USB 2.0 ports on the notebook. I really haven't seen anything like this in my entire career.
I even downloaded the file efiootBOOTX64.efi and replaced the one that Windows come with on the specified folder on the USB stick ....
Why is so difficult to choose the USB boot drive on the newer notebooks? How can I boot from USB?

I've had my IdeaPad Notebook P500 for over a year, and rarely had an issue with it. Today, I accidently touched the F11 key, which happens to be the "Brightness minus" key.
Immediately, the screen went very dim, to the point where it actually hurts my eyes to be typing this.
I can adjust the brightness sliders up and down on the screen, using both the F11/F12 keys and the slider box available from the "Brightness" selection under "Settings". Even though the sliders go up and down, the screen stays the same very dark level.
Windows 8 64-bit is my OS.
I have uninstalled and re-installed the Intel HD driver.
I have shut down the laptop and turned it back on while holding the F12 (Brightness plus) button. It was useless, though.
I have rebooted several times.

Just got the y510p laptop and am trying to install Ubuntu so I have this bootable DVD and I wanted to try Ubuntu before installing as usual but I can't get the laptop to bot on dvd. On boot menu options there is only EFI and some kind of network options but no dvd. I tried following instructions here but no matter how many times I press F1 during startup, I can't get to boot menu and windows starts directly: [URL] Is it not possible to boot on dvd. The dvd is ubuntu 13.10 supposedly compatible with EFI and secure boot. I don't understand why there is no option to reorder boot devices like on all my older PCs.
I manage to get BIOS setup pressing restart and shift and then selecting UEFI firware settings and I do get to bios setups but again no way to find the option for booting on a dvd.

I bought a y510p ideapad from newegg a couple days ago and recently got it. i've been trying to set it up and all that, trying to get rid of the programs that came preloaded with the laptop because I wouldn't think i'd need them. I then shut it, put it down and opened it again and now it won't turn on. It seems like both the power indicator and the battery indicator light are both on, as well as the power button light, but the monitor itself is blank and i can't hear the computer being on. I've tried holding down the power button and resetting it, as well as removing the battery and using only the AC to see if it would turn on but to no avail. I'm worried i might have deleted something important, but I was mostly deleting programs related to shoddy media players and other services of the like. It's pretty upsetting I just got this laptop and it's already died on me!

I bought my y510p brand new from Lenovo about 11 months ago. About 2 days ago, my fan suddenly started making a very loud buzzing/grinding noise. Prior to this, it was perfectly quiet. The fan makes this noise inconsistently, and at this point, leaving it on a flat surface keeps it quiet. However, any tilting or jostling of the laptop makes the fan start buzzing again. I have noticed that running the dust removal utility will stop the fan from buzzing, and this seems to be the only way to return it to producing a regular sound after it has started.
I really don't think my fan needs to be replaced, but I am unsure what is causing this problem. I have never dropped my laptop--and its spent almost its entire life on my desk. The only thing that's changed is I moved it after it had remained in the same spot for several weeks--because I am currently traveling.
The inconsistency of the noise and the newness of my computer tends to make me think the fan hasn't worn out yet.

Recently I purchased a Lenovo Ideapad Z510, model name 20287, MO: YB03120328. According to the specification from my reseller (Dutch webshop [URL] and the Lenovo box it was shipped in, this laptop should have a 1000GB hard disk + 8 GB solid state memory (SSD) for caching. My problem is that I am not sure if the 8 GB SSD is working.
The SSD does not show as a drive in "My Computer", it does not show in Window's Disk Management utility (see Figure 1), Intel's Rapid Storage Technology does not show the possibility of using the SSD to accelerate performance (see Figure 2) and when running ExpressCache (with the command "eccmd.exe -info") the program tells me "HFS Volume is not mounted" and "ECCmd exited with error 0x10df (4319)".
All these clues lead me to believe that in fact no 8 GB SSD is installed, or if it is, that it is not working properly. Any additional ways of testing I could use to confirm it is or is not working?

The first week my Y510p worked perfectly, I had a little trouble to install linux but I finally got it. Then, suddenly the laptop stop working. I restarted the laptop and it didn't want to start again... I got a completely black screen, I know it is on because of the keyboard backlight. The screen is completely black, there is no way to get into the recovery menu or BIOS setup. I expend 1 hour last week with lenovo support trying to get it into de BIOS or recovery menu in all possible ways and nothing works. What can I do?
