Lenovo P/Y/Z Series :: IdeaPad Z500 Won't Boot Up Without Power Cable Plugged In
Jan 9, 2014
My z500 cannot boot up without power cable plugged in. Usually,a few seconds after I saw the lenovo logo,the system will suddenly shut down just like the battery was removed.however,if I connect powercable to the laptop and power on,everything is fine,I can enter windows 8,or ubuntu,after I enter OS,I can disconnect the power cable without any problems.the battery is healthy and can last for more than 2 hours.
So far I tried the following methods:
1.update BIOS
2.update battery firmware
3.reset BIOS
none of them worked for me....

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 got to admit that I got this Laptop for quite a while now but it is still bothering me that it reboots automatically after shutdown when power cord is plugged in. Without the power cord it works as it should.....

I have a new z500 that I've downgraded to Windows 7 64bit. For the most part I have everything working. I accidentally hit the brightness + (yes, +) and it instantly dimmed the screen to where it is barely viewable. It seems that hitting that one key decreased the brightness to the minimum amount. I've rebooted, looked for a setting in the BIOS, hit the Brightness +/- and can't increase the brightness. It is interesting because the other hot keys work correctly. I've even upped the brightness in the Control Panel, but nothing seems to work. The screen is extremely dim whenever the machine is powered on (including the BIOS), not just in Windows. I tried a lot of intel chipset drivers, the available Intel HD 4000 drivers in Win8 and win7 too, but nothing working. How to up the brightness?

I have an Ideapad Z500 with an W8.1 installed on it. I updated the bios to the last version but after that I can not control the luminosity level anymore. When I try to do it pressing the Hotkey it trurns to the lowest level of luminosity and I can only fix it by pressing the hotfix key when the laptop starts. I can not return to the old bios version. What shall I do?

I have trouble with my audio driver on my lenovo laptop. After I updated BIOS to version 1.21, my sound stopped working. I tried to reinstall audio driver, but when I reboot my computer, sound is not working again.
I read about flashing BIOS back, but I dont know where to download old version.

I have an ideapad z500 which I'm happy for, but it annoys me that when 'm at my college I can't properly connect to the wi-fi the school has. When I connect, I'm on for usually about half an hour, but then I get the "limited connection" yellow triangle and I have to deactivate the networkcard before I can get a normal connection.
Other times I simply just can't connect, it tries but it fails. When it does, I have to reboot the computer before it succeeds, and that's no good when you are working on a project. At home i have no problems, it works nicely.
Also, how to enable the WiDi on the z500.
My PC is running Win 8 with the Intel Centrino n2230, Intel 3rd. gen i7 (3632qm)

I open this post to report a brightness problem on Lenovo Z500 Ideapad. Yesterday I've upgraded to OS Windows 8.1 and when I adjusted the screen brightness it goes off, and brightness adjust function doesn't works. I've solved my problem reinstalling the Intel video drivers, downloaded from Lenovo Driver Support.
It seems that Windows 8.1 upgrade disables video drivers.

Purchased from Amazon 2 months ago and worked perfectly without a hitch until a few days ago when I got on the receiving end of the win8 equivalent of the BSOD with the . From them on I ended up with slow boots random pauses etc. I opted to refresh the PC without affecting any files but toward the end of the reinstall the BSOD appears and now all I had was a black background with only a white cursor.
Left that for over a hour, nothing happened so held down the power button to force shutdown. Found that Z500 no longer boots into win8 so eventually decided to do a clean reinstall with the onekeyrecovery via NOVO button. This should have been the end of all the problem I was having but unbelievably the problem is still there.
Research what I could about this and found that the slow boot is caused by hard disk constantly being thrashed about by a system file ntoskrnl.exe. I tried updating the wifi driver and it appeared to have done the trick until the next day when I booted up the system again. It appear that the constant hd activity goes away after a few hours of leaving the PC on.
Anyway I have drawn a blank as to what's going on especially as everything was working perfectly until up to that point with no signs of system conflict.

I bought my lenovo z400 ideapad beginning of April this year and just about two days ago it just turned off and though I plugged it in later it started saying 'plugged in but not charging'. What do you think is the problem?
Furthermore I lost the receipt ( the sales receipt) but there is still the model/series no. , is the warranty still on?

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.

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 have just received this laptop. I followed the instructions out of the box, installing the battery, then connecting the power. The battery started charging that first time, but after that, any time I tried reconnecting the A/C power supply, the laptop would not recognize the adapter and I am not able to charge my battery.
I have tried the following steps:
1. Shutting down the computer, removing the battery, and starting the computer from the A/C power supply. The computer will not recognize the A/C power supply to turn on the computer.
2. Updating all the power management drivers. Everything was already installed properly.
3. Using the Lenovo Energy Management battery gauge. I must have the A/C power supply plugged in to use it, but the computer still won't recognize it.
4. Held down the power button for 30-40 seconds then reset the BIOS to default settings. No change
5. Tested my outlets and connections between my AC adapter cords. Everything is working properly.
There is one way that I can get the computer to recognize the AC adapter, and that involves all of these steps shown below, but when I unplug the AC adapter I am right back to the beginning, and I have to redo the whole process. I have just received this laptop and I am quite sure that you shouldn't have to go through this process every time you want to recharge the battery, or use your computer while only powered by the AC adapter.
Steps I have to take to recharge my battery:
A. Disconnect the A/C power supply.
B. Shut down the computer.
C. Remove the battery
D. Connect the A/C power supply
E. Start the computer.
F. Uninstall all battery drivers that are labeled Microsoft ACPI Compliant Control Method Battery (which come back every time).
G. Shut the computer down.
H. Disconnect the A/C power supply.
I. Insert the battery.
J. Insert the A/C power supply.
K. Start the computer.
That is the ONLY way I have gotten my computer to recognize the A/C power supply. I know the power supply is functional, but why I have to go through all of those steps for the laptop to recognize it.

I'm trying to Install Debian GNU/Linux on my Windows 8 Ideapad Z710, and I can't even get my laptop to boot from external media. From the InsydeH20 Setup Utility, I've so far disabled Secure Boot, set Boot Mode to UEFI, enabled USB Boot, enabled PXE Boot to LAN, and set my EFI boot order to 1) EFI Network 0 for IPv4, 2) EFI Network 0 for IPv6, then 3) Windows Boot Manager (no other options). I'm not actually trying to boot from a network, I just want to boot from the onboard DVD drive or my USB DVD drive. When I boot with these settings, I get the error: EFI Network 0 for IPv4 (...) boot failed, then a similar one for IPv6, then it boots to Windows. Why can't I boot from DVD or USB?
Another thing I've tried is setting Boot Mode to Legacy Support and Boot Priority to Legacy First (with Secure Boot disabled) which results in my laptop booting to straight to Windows even when USB ODD is first in the boot order.

My Lenovo z570 will not boot from CD. I have the system recovery CDs and another bootable CD that work in another Lenovo so I know the discs are fine. The boot order is set properly (CD first) and even hitting F12 on the boot up and selecting the CD drive again doesn't work. The drive does work - I can burn and play CDs. I uninstalled the drive and reinstalled and updated the BIOS to the latest. I see others with this problem have been advised to change UEFI or Secure Boot setting but these options are not available in my BIOS.

Shortly after I received my laptop, I installed a third-party battery monitor, BatteryCare, to monitor the battery in the laptop because I'd used it on previous software and liked having a second source of information. I've been running the laptop like a desktop for the last few months though and havent had to pay any attention to batter life, since the thing is always plugged in so I decided to delete BatteryCare.
The uninstall went fine, but when I restarted the computer I noticed that the icon displaying remaining battery life did not reappear. I went digging to see if the uninstallation might have uninstalled a driver but I couldn't find anything indicating a problem like this. I still have the Energy Monitor - just nothing showing up much juice is left in the battery.
Any pointers on what drivers/devices I might have to reinstall to get power monitor icon back. I checked the Driver Matrix, here, but I couldn't find anything about solution. Should I just reinstall the Energy Management utility?

I got my Ideapad y410p a week ago. It came with Windows 8 and many useless softwares installed. It was taking around 3 minutes of time and immediately i updated my os to 8.1 (x64). Even after updating to 8.1, the boot time didn't get any better. I unistalled useless softwares like Mcafee, Cyberlink tools and many and installed AntiVir and Visual Studio. Turn on Fast startup is also enabled. But what is painful is it still takes 2 minutes and 31 seconds plus to load my desktop. What is more painful to me is My old laptop (Amd Dual Core, 3GB Ram with Many softwares installed with windows 7) loads earlier than this.
Lenovo Y410P, Interl Core i7 4th Gen, 8 GB RAM, 1TB HDD, 2GB Graphics

I have an IdeaPad V570 that experienced a total hard drive failure (be careful how hard to close the laptop in frustration) I had Best Buy try to recover data and opted not to pay for the recovery after the only crucial data did not seem to have been recovered. Best Buy told me the rest of the system seems to be intact so they could install a new Hard Drive if I wanted it back. They made me offers to completely restore the system at a price but I decided to save money thinking I should be able to restore the system myself. So they installed the hard drive and that was it.
I decided to go with Windows 8 after learning that support was beginning to wain for Windows 7. I purchased the OS from Best Buy and I am attempting to install it. So far that is not going well. The BIOS sees the CDDVDW drive and the HDD, both are listed in the BOOT menu with the right names. However the computer is not booting from the WIndows disk. I get a message ending with :
PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM
At which point it take me to the Boot Menu. I can see the order I have set for Booting is:
1. ATAPI CD: TZSSTcorp CDDVDW TS-L633F
2. ATA HDD: WDC WD10JPVX-22JC3T0
3. PCI LAN: Realtek PXE B03 D00
It seems to me that the system is trying to boot in that order but the CDDVD drive is not responding, the HDD has nothing on it so it goes for the PCI LAN and there is nothing for it to do so it returns the error an sends me back to the Boot Menu.

Yesterday, I updated to win 8.1. The process appeared to go smoothly, but I now have a number of issues:
1 If I close the lid and reopen, the sytem does not wake up. It does not wake up if I press the power button. All I can do is a hard shutdown and reboot. This occasionally gives an error message on restart, but has not produced any solutions.
2 There is a message about secure boot not being configured
3 The support app has a cross on it and won't work
No doubt there are other problems, but number 1 is the killer....

The problems still exist after I do a fresh restore with Lenovo DVDs. Also ran the Lenovo Update & Driver utility.
1. My W530 wont boot or start if I have a External drives plugged in. It stucked at "ThinkPad" screen. I have to unplug the external drive and press/old power button to shut it down. Same thing happened when the laptop is docked.
=> Contacted the technical support today. They told me I have to unplug and plug it back in everytime. I told him that there is a reason I got the dock station so I don't have to unplug and plug my external drive every time.
2. I have no problems booting if thumbs drive plugged in. But it keep "Auto run" everytime I turn on the machine.
I do not have this problem with my W500 and W510.
W530, Intel Core i7-3820, 32G DDR3 RAM, 180G Intel SSD, Windows 7 x64, NVIDIA Quadro K2000M.

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?

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.

My D600 will not boot up unless the power cord is plugged in. Is there some switch that I hit by mistake? Can this be corrected?
I guess basically it doesn't work on the battery unless it is plugged in but the power shows 100 % for the battery
