Preferred Solution: Lenovo ideapad Z500 - can it use a windows 10 boot disk?

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.)

Hello all, I have a Lenovo Ideapad Z500 taking long time to boot (almost 30 min) The computer is stuck with black screen during 30 min, before the lenovo logo appears and then it boots fine. Before logo, just a black screen and power looks good. The problem, the fans don't work and the computer gets very warm. Sometimes, because the high-temperatures, it automatically switches down, because temperatures, before seeing the lenovo logo. With lenovo diagnosis software I have checked all the hardware, and the tools says all hardware is ok. My os is Windows 10. Could you please, somebody help me to solve this problem? I'm afraid the heat of the start could harm my computer. Why this boot is taking so long before logo? Thank you in advance, ip

Product key is stored in BIOS, so there is no need to use any app to read it.Download a tool to create bootable media from Microsoft website and install Windows 8.1 using it:https://www.microsoft.com/en-us/software-download/windows8 Moreover at first, you may try to restore your Windows 10 to factory state (do a backup of all important data first).

Hi utkutrk , 
 
Welcome to the Community Forums.
 
You can try testing individual key specially FN and spacebar if it is working.
 
Turn off the machine and disconnect the ac charger and battery if you have the tools.
Press down the power button for 12 seconds to drain flea power.
Place back the battery and connect the ac charger.
Restart to check if backit keyboard works ( test further with FN + spacebar pressing 2-4 times).
 
Update us how it goes.

Hi Guys,

I am a member of the sevenforums and currently have a win8 laptop so thought I'd sign up here (seems to be the same people behind both forums).

I'm having a little trouble and would really appreciate some feedback.

My Lenovo ideapad z500 had 2 keys (K and I) that stopped working (they worked on the touchscreen) and then after that the delete, 8, and arrow keys topped working. Not sure why.

Before I get the keyboard replaced I'm wondering if it could be something else? There's no water damage and I haven't dropped it so I'm confused. I was told it has to be water damage but maybe 1 drop from the condensation on a glass of water is all I can think that may have affected it.

Would be great for some input on this issue.

Thanks!

A:Laptop Keys Stopped working - Lenovo Ideapad Z500 Win8

I was told it has to be water damage



Not true. In fact, water in the keyboard normally does not cause permanent damage. That is, once the water dries, all works again - most of the time. But that does depend on many variables - type of keyboard membrane, how much water, if just water (no sugars or cream, for example), and how much dust, dirt, oily hair/dander, cigarette smoke, cookie crumbs, etc. are under the keys when the water was spilled. The greater damage generally comes when the water works it way through the keyboard and into the computer's electronics.

I would try a regular PC keyboard first to see what happens. If all the keys work properly with a standard USB keyboard, then you can be pretty certain it is the notebook keyboard at fault, and not something more serious.

Hi.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 efi\boot\BOOTX64.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?Does someone have a clue how can I boot from USB?Thanks in advance!  Bupitz

A:USB boot for Ideapad Z500

Hi,
 
I don't think I can be of much help, but a couple of things to try:  if your USB flash drive is formatted NTFS, it will only boot in legacy mode if it is bootable at all.  One thing you might try is to set the partition active if it isn't already.
 
If you want to boot in UEFI mode, format the flash drive with a single FAT32 partition.  Copy the contents of your install DVD to the flash drive.  If you're using an ISO copy the contents of the iso using a tool like 7zip.  UEFI bootabiliyt doesn't require using a special tool to prep the drive.  Just format it and copy the install medium to it.
 
Win7 requires CSM support in bios to boot successfully in UEFI mode.  That may always be enabled in UEFI mode or it may be a separate option in BIOS.

Good day everyone,I just recently bought a new laptop which is a lenovo ideapad 110-14isk. When I booted it up, I noticed that it can't respond quickly so I opened task manager and saw that disk usage is always at 100%. Due to this, even shutting down takes a long time and seldom I force it to shut down because it is very unresponsive. I observed the laptop for a few days and found out that windows update was slowing it. I disabled the Windows Update Service, and when I rebooted it, the disk usage is at normal levels. So my question is, how can I update my laptop? and is there any way to use Windows Update without the laptop lagging? Hope you can help me. Thanks in advance.

So, after some time of having reformatted the laptop in favor of Windows 7 from the original Windows 8 OS, I encountered a problem with the UEFI system which forced me to configure the BIOS with the Legacy config, lest the system would not boot. While the system works just fine with a Legacy configuration, it now always has an entryway to the Windows Boot Manager first even though there's only a single OS to choose from: Windows 7. Is there any way I could bypass the Windows Boot Manager whenever I'm making a coldboot of the system?

Hi, I'm hoping this is the right place, I'm having some problems and I don't know where to turn... I do a lot of work with video, my original computer was too slow so I decided to upgrade the hdd (to 500GB 7200rpm) and add ram. (The hdd works like a dream!)I went through corsair.com and they showed me a list of compatible ram products. I then took the info I learned from their site down to my local computer store and bought the 4GB Kit. (Corsair RAM suggestions for the Lenovo Y510, I bought the highlighted 4GB Kit)After reading and watching a few things on installing ram it seemed simple enough so I went ahead with it and removed the two 1GB sticks out and put the two new 2GB sticks in.When I started up the computer...nothing happened. The lights go on I hear the fan and feel the hdd spinning but nothing on the screen for me to select. I tried waiting 30 seconds before installing the sticks, I tried alternating sticks, putting in one at a time even. I even put the old sticks back in. Still nothing. Sites say press f2 at start-up, still nothing, and they say press f8 to go into safe mode again nothing. A blank screen. My instruction manual tells me that there is no software to download and that BIOS in the POST process should detect the newly installed ram.What's going on?  Did I blow out my screen??? I know I'm way past the warranty...so I'm wondering who I call/ speak with?  Do I send it in to Lenovo to get it fixed?  How much will it cost ...

A:Computer Won't Boot After Upgrading RAM, Lenovo Y510 Ideapad, Windows Vista, 2GB to 4GB RAM

You say the computer experiences the same problem even with the old RAM? If that's the case, the most likely scenario is that you are installing it improperly. You can take your computer to a local computer repair center and ask them to quickly show you how to install RAM. It should be a very quick fix, so don't pay someone to do this. Even a knowledgeable salesperson at a computer store would be able to look at it and fix it. Alternatively, it is possible you damaged both the old RAM and the new RAM (very unlikely, but I suppose possible via extreme static discharge?). Or you somehow damaged the motherboard or other component (I don't see how this could possibly happen, unless you did something incredibly wrong, and even then it would be hard).

Hello, I have  a lenovo Z500 touch that I have seldom used in the 3 years since I bought it mostly playing music when on holiday. I have just started trying to use it with Cubase music production software with an external monitor via HDMI. Several times a day the system freezes and can only be recovered by hard reset. There is no sign in the system event log of a problem until after a restart when the kernel reports that the system wasn't cleanly shut down. The system is much more stable using only the integrated display. I discovered that there is a downloadable Lenovo Diagnostics CD which is built on a Linux base. The Z500 freezes every time in the Video Card stress test both with and without an HDMI connected display. It has now also frozen on one of the extended memory tests. It is exactly the same type of freeze as occurs with Windows. So, this is not a Windows problem as it occurs in the diagnostics Linux system. In Windows it only ever fails when a second display is connected so looks like it is related to the Intel HD 4000 graphics. Running HWMonitor there is no sign of high CPU temperatures. At the point of freezing, which I have just directly watched, the screen flickers. For a short while after the freeze the keyboard back light can be switched on and off and then about 30 seconds after it stops responding. caps lock and num lock don't respond immediately after the freeze.
