Lenovo P/Y/Z Series :: Z50-75 Freezes After Unplugging From Power Outlet
Nov 3, 2014
I'm having an issue where my lappy completely freezes up when it is on battery power. It will boot off of battery fine, and I can click to the desktop, but then all icons become unclickable and all keys/input functions cease to work, and after about 30 seconds, the mouse won't move anymore. If it is on and then unplugged, it instantly freezes. I checked and I have the most up-to-date bios and drivers. I'm a bit perplexed as I've never run across an issue like this before.

I bought this computer on Jan. 1st and so far I love it, however, a few days ago I noticed that everytime I connect or disconnect my charger the screen goes black for a few seconds. It's not the worse problem however it is extremely annoying! I tried checking both the intel graphics settings and power management settings to see if an adjudtment would work but it has not.

I have an Acer 7720-6604 notebook. For Power Settings I usually keep it on "High Performance" when plugged in (I'm usually gaming). I've found that when I unplug it with this setting, it acts like it's on "Power Saver" mode, which equals a big drop in frame rates when I game. I checked out event viewer and it shows this message as associated:
"Event 2, Kernel-Processor-Power
Performance power management features on processor 1 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware."
I've looked all over and can't find any way to fix this problem. I really haven't seen anyone else have the problem actually. It's bad though because it really makes games unplayable and shouldn't be happening on a relatively new laptop (bought it only about a year ago). I don't know what firmware I need to update or what I need to do if that's not it.
I did uninstall all of the empowering technology programs, including epower management. I'm not sure if it's related... I thought it was just a power scheming tool and windows has it's own in the control panel anyways.
Someone please help. I don't want to have to format or send it in for repairs if I can help it. Acer has an expensive repair fee (so I hear). I will format if I have to but I don't know that it will fix anything.

- When I put the laptop in sleep by closing the monitor, if I open the monitor later, it will wake up but the screen (windows 8.1) is freezed.
I can move the mouse, and the keyboard is active (caps and num lock). However none of the controls on windows screen are active (password, shutdown button , etc). Ill need to keep the power button until it shuts down.
- If I put the laptop to sleep using the windows shutdown/sleep/restart option, it wakes up without problem.
- I tried to turn on hybrid sleep, but it made things worse. When waking up the monitor will be black for ever (the hard drive is working).
- I have installed the drivers from lenovo website. What else should I try?

I recently purchased a Lenovo y510p for college. I do not use it that often because i have a nice desktop at home and have not moved yet. When i do use it, it freezes 3-5 minutes after the start up. during the freeze i can move the mouse but when i click on anything nothing happens. When i mouse to the corners the normal windows 8 thing dont pop up. After it gets done freezing for a few minutes evertying i clicked on or did during the freeze pops up really fast.
I believe i have updated all my drivers. i unistalled mcafee and really only have a few things installed liked Steam, and Final Fantasy 14: A Real Reborn. Sometimes after the freeze windowns stops responding and i have to hard reset. At that poing i somtimes get stuck in a boot loop and just have to keep resetting till it fixes itself. I also installed chrome.
I dont want to have to reistall windows or do a factory reset. i do have a warrenty but i start school in 2 days and cant really ship this anywhere. I dont have the serial number with me but i have the laptop with the duel graphics.

We bought 12 X240 pc's and installed a Windows 7 64bit OS on them. We are having problems on several laptop (5 so far) that they freeze several times a day. The mouse icon changes in the processing icon, you can still move your mouse but can't click anything or even press ctrl + alt + del. Have to long press the power key to get them to power off.
I already read that there were problems with the fingerprint reader software, uninstalled it but still having the problems (fingerprint reader is disabled in BIOS). Also upgraded the fingerprint reader software to the latest version on another pc, but same problem.
Ran solution center on one of the PC's, didn't find any problems. Ran system update and updated all to the latest version. Also tried to change the power settings to Performance mode in windows. But problem keeps coming back.
I tried installing the latest Intel graphics driver, but it fails to start stating that you need a version from the manufacturer. No error messages in the windows event logs.
X240 model is 20AL00C1MB.

My Ideapad Z570 has been doing this for some time - the screen is black, lights are on, and won't wake up. I inevitably end up turning it off, so I lose my work.
I've delayed the sleep mode to reduce the number of instances...

I have had my Ideapad U410 for about 18 months now.
Recently my bluetooth mouse has stopped working after a few minutes of use. If I switch the mouse off and then on again it works again. I assumed that it was a problem with the mouse so I purchased a new one.
Guess what. The same problem.
Now with two blutooth mice displaying the same problem I am guessing that the trouble lies within the laptop, but what to do to identify whats going wrong.

I run the W530 with a dual boot setup with Windows 7 and a Ubuntu distro, with the Windows as the default one.
Every time I try to boot and there happen to be a memory stick or a drive connected to the computer, it freezes on boot at the Windows logo. If I unplug the memory stick, everything is fine and it boots up normally.
Ive purchased a Thinkpad 12,7 mm SATA HDD Bay Adapter III and a Samsung 840 EVO, 500GB, SSD. Now when I swapped the DVD drive with the new SSD the same freeze happens ever time I try to boot. Ive tried to connect the new SSD to the computer and formatted it beforehand. But it keeps freezing.
Im not sure if this relates to my dual boot setup or what.

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.

For the first week or two it worked fine and everything was going really well. Then about a week or two ago it started acting up. It is freezing programs(firefox, IE, Chrome, explorer, Flash CC, blender, and a few other programs I needed to install for school. It sometimes freezes on startup and I have to hold the power button down to restart it. Sometimes when it restarts it takes 10-15 mins to fully boot up and load up to the login screen.

I have a Vaio Z550N and although it was working perfectly until this point, now I am having the issue of the computer freezing up (completely non-responsive) when I re-attach it to the AC adapter after having had it on battery power.
It doesn't happen every time... but it is enough to be exceedingly irritating. The only major change I have made to my computer recently is upgrading the BIOS to the latest version from the Sony Support site.

When my laptop is plugged into AC power, and I decide to move to another room and unplug it, the laptop suddenly freezes. All the programs do not respond and the only way to fix it is to reboot.
HP tech is trying to help my by telling me to test the battery life and resetting the bios, however this laptop is only 2 months old and I had the problem since the begining.
Its a dv3 Pavilion.

I have had my Lenovo U430 touch for about a month now, and have noticed a problem with it. Sometimes when I leave my Lenovo u430 touch alone (with full battery), and sometimes it will just power off without me doing anything. It even happens occasionally when I dont use it for a few minutes while im working in front of it.
It is definitely a power-off problem for me, rather than hibernate/sleep as my programs are no longer running when I turn it back on.
Hasnt caused any lasting damage as yet but am worried it could happen while im working on something important.

Using my Ideapad Y410p this morning (six months old), the computer abruptly crashed and shutdown with no warning of any sort. Straight to black screen and lights went out. I thought perhaps it overheated and shutdown as some sort of safety measure, as my old Dell used to do that. The laptop was warm, but I've seen it get hotter and still perform.
Now I can't get power back. Pressing the on/off button doesn't get me any sort of noise or lights. Tried unplugging the battery and AC power for a while, and still not working. Held down power button several times seeing if it would reset something. Opened it up the cover and took a look but didn't see anything wrong. Popped the RAM cards in and out. It's just dead in the water.

I bought my Lenovo Y40 on the Lenovo Web site a couple months ago and recently, to turn on, I have to press the power button twice. When I press just once, the Lenovo`s logo is displayed on the screen, but after 2 seconds everything turns off. On the second trying, finally the laptop turns on and the windows is started.
In addition, rarely the laptop stucks on the lenovo`s logo screen, being necessary to hold on the power to reset it.

Windows did an update today, and now my pc won't run on battery power. The battery icon is just empty and says plugged in and not charging. This is the first time I've encountered this problem. When I unplug it, it immediately dies.

I have a W530 (2436 CTO) ThinkPad purchased 11/10/13. It will not power up.While in use the screen went black, then the unit tried to reboot. Just as Windows began to initiate, the screen went black again. It immediatly tried to restart about three times in quick succession, about 3 seconds long each time. It was powered with the AC adapter at the time with the battery in place. I have tried all combinations with or without the battery or AC. In either mode, the power button lights up for approximately 1-2 seconds, then goes black. I have tried holding in the power button for 30 seconds. Nothing, other than about a 2 second light, then dead.
I have never received any power warning messages, low battery warning or the like. The only unusual behavior I've ever had is about half a dozen times I've had to do a hard power down. But not recently.I have tried the removing and replacing the SSD. I have removed and switched the two memory boards to test for a bad board or bad connector. None of these have solved the problem. I’m guessing the SSD failed, or perhaps a bad BIOS chip. I can easily replace the SSD, but 9 months of moderate use seems like a short lifespan for even an SSD. I can't update the BIOS (if that's the issue) because I can't get the unit powered up.

I bought my X240 from a Lenovo authorised distributor (the one that comes with a svc centre) 3 wks ago. They told me that the one I bought does not come with in-built battery and so it came with a 6-cell batt. i asked why and they said its this way. i bought the set. Have I been lied to? i have not come across a set on the internet without powerbridge !!

I've looked at the other threads and tried removing the battery while the laptop is off for 30-40 seconds but it doesn't run because it's not getting power from the charger at all.
The laptop is a couple years old and the hinges on both sides have been pried off (can provide pics) but I never had problems until now - I plug the charger in but it won't charge and even if I pop the battery out it STILL doesn't charge!
One night, I had to set the charger upright in order for it to charge. Today I had to set the bulky and heavy part of the charger higher above the laptop in order for it to charge. Now, how to get this thing to work because proping the charger upright or higher than the laptop isn't working anymore!
I've noticed a couple weeks ago when I was visiting my parents that the adapter emits a beeping sound - notice that I said the adapter NOT the laptop. If I unplug it the beeping sound fades. The beeping sound comes from the adapter and when I unplug the cord going from my laptop to the adapter you can hear the beeping sound fade away from the prongs that conect the adapter to the laptop (not the prongs that plug into the outlet).
Like I said before it doesn't matter if I've plugged it into an outlet with OR without the battery in it, the laptop does not receive any power from the adapter or recharges.

Every 5 to 10 minutes after startup during a small period the laptop returns a blue screen with this message DRIVER_POWER_STATE_FAILURE.
It’s so devastating to have to witness this every time again. I thought I bought a reliable laptop but now I have doubts. What can I do to stop this. I have looked through the other messages but I can’t find the right solution for my problem.

I've have had a Lenovo g500s running windows 8.1 for almost a year and never had an major issue. But recently I have found that it will not turn on. I have found that by taking out and putting the battery back in will rarely result in the battery light blinking in red. If i try to turn it on at this point it will turn for a few second "prepare for automatic repairs" and then in a few seconds turn back off its original turned off state. I have tried "Flee-Power" while calling technical support and it made a small noise and then issued a burning smell. It's 1 year warranty is still valid.
