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.)

The laptop came with pre-installed Windows 8.1 x64 and I wanted to install Windows 7 x64 Ultimate so I could enter it to a domain. I made a bootable usb with Win7 and reached the partition section on the installation wizard.
I deleted all the partitions that the system already had (Recovery. MSR and others) and procceded with the installation succesfully. After the installation finished, my system was not able to boot and it is restarting every time it reaches the
"Starting Windows" screen.

The partitions for the HDD in the beggining, looked like this.

Hi, i got the Laptop Lenovo IdeaPad 100-14IBY Model: 80MH003TGE and tried to replace the interal 2gb ddr3l sodimm ram with 8gb ddr3 sodimm ram and the laptop won't start up, so my guess is that the mainboard does not support the normal ddr3 ram. When i switch back to the 2gb, everything works just fine.I even tried to update the bios, but that does not seem to do the trick either. Can anybody confirm this or has information on the subject?  

A:Lenovo Ideapad 100-14IBY change the RAM

Hi Bontempi1950 , 
 
Welcome to the Community Forums. 
 
As per product specification and Hardware manual (page 26) :
Memory:  DDR3L-1333 MHz / 1600 MHz SODIMM × 1 (max 8 GB) 
 
DDR3L socket on the board would only be able to accept DDR3L (low voltage) RAM 
Inversely , the DDR3L would work on a DDR3 and a DDR3L socket board (backward compatible). 
 
Related discussions here and here.
 
Hope this help answer your query.
 
Regards

Hello guys, I just bought a new Lenovo 100-14IBY Ideapad without an OS. Installed Windows 8.1 and all of the drivers from the Lenovo Support page, but the Wireless adapter is just not working, it's not even recognized in the Device Manager. I tried switching the Airplane mode on and off again, checked the configuration settings in the BIOS and the WAN is enabled. I don't see a physical Wireless switch anywhere on the laptop and there is no "F" button for turning the Wi-Fi on and off on the keyboard.. so at the moment I don't know what else to do. I have also tried all of this on Windows 7 also, of course no success. Could someone suggest something please? Many thanks!

Hello, I like to replace my standard harddisk in my Ideapad 100-14IBY with a SSD. I have read the corresponding Maintenance manual and followed the instructions step by step.It is impossible to remove the keyboard without breaking it, it seems like it is glued. Is there any advise, other than sending it in to a service partner, how to safely remove the keyboard ? I just don´t get it why Lenovo really makes it so hard for users to change the drive in this particular model. Thank you in advance

System: Windows 10 64 bitAfter turning it on from sleepmode the keyboard and mouse weren't working. So I restarted it and Windows installed some updates. The keyboard and the TouchPad still weren't working. The USB mouse was, also the FN keys. I tried the F6 button it didn't help, so with the screen keyboard I was able to log in and type the pass. After that I went to device manager and the Lenovo TouchPad had a yellow triangle. So I went to Lenovo website and downloaded the driver, uninstalled and installed the new one, restarted again - no luck. When I clicked on the mouse menu in control panel popped up a message that said "couldn't connect to the driver. Etc etc" In device manager even after the update it was with yellow triangle. So I saw in a thread here in the forum that sometimes the installing of Synaptics driver helped, but after that even the USB mouse stopped working and the FN keys too, so I am no longer able to log in to the notebook with the screen keyboard. I can't enter BIOS with F2. Somehow I managed to get into recovery and the USB mouse was working there but when I tried to go into safe mode I can't because of the FN keys. Any suggestions how to solve this problem?

I installed Windows 7 Professional 64-bit on my Lenovo ideapad Y430 (which came with Vista Home Premium 32-bit). It worked fine for a few hours. However, it now freezes up within 1 minute after I sign on after rebooting. The cursor stops moving, Task Manager won't come up, no disk activity, etc. Booting in Safe Mode works fine, so I'm thinking it's an issue related to a driver or service that doesn't load in Safe Mode. Event Viewer doesn't reveal much of use; only the fact that I needed to power off without shutdown. Vista still runs fine on another partition.

Has anyone seen anything like this, or have any ideas on how I can get Windows 7 running again (e.g., by identifying and removing/updating the offending driver/server, if that's what's causing the problem)? Any help would be greatly appreciated, thanks!

A:Windows 7 Pro freezes on Lenovo Y430 ideapad

(Self-plagiarisation: )

The fact that it seems fine (as it's never happened - not even once?) in safe mode is A Good Thing, because it suggests that the causes are software-based. Something that loads in normal mode but not safe mode is presumably the culprit.

One way to start troubleshooting is with the MSCONFIG utility. Start off by choosing the "diagnostic" startup mode and rebooting. If that works, as in there are no hangs, go to "selective" startup and disable/enable the various optional components until you zero-in on the culprit.

If "diagnostic" mode doesn't stop the hangs from occurring in normal mode, uninstall your anti-virus and any 3rd-party firewalls (disabling them is not enough). Test what happens when running without them.

Sounds like you got a driver from Microsoft update that is causing you problems. Try a system restore and then turn off automatic updates so you can then choose which updates to install. Watch out for driver updates and do them one at a time till you find the one messin' you up.

NOTE: Just because it's from Microsoft doesn't mean it's the best choice.

I have to click ALT CTRL DEL to reboot it again and it will then show lenovo logo and boot into windows. This happens on every restart. Essentially restart functionality is as good as shutdown. Its better to shutdowns and then click the power on button. Here is what i have discovered:- The issue disappears if i am not logged in into my windows account. So basically if i boot into windows and dont sign in, then restart, it will restart into windows and go to login screen.- The issue pops up if i am logged in into my windows account and click the restart button, no matter how long i used the laptop Here is what i have done so far:- Reset bios to default setting - Reset windows to defaut- Installed windows from scratch using bootable USB.- Flashed the latest bios - Installed and uninstalled all the lenovo drivers- Installed a new SSD replacing the hard disk The issue hasnt resolvedNeed some help ThanksRon

I used GPT, EFI, disabled hot-keys, disabled secure boot, disabled fast boot).Hardware is definitely OK (I installed later Ubuntu and it works perfectly).

Hello,I just installed the free Windows 10 upgrade on my Lenovo Ideapad p400 touch last night.  I woke up this morning and booted up my computer, and everything was fine until I attempted to change the brightness.  When I tried to do this, my screen went very dim, and now I can't adjust the brightness (and I can't read my screen well, either).  Normally, I would install/reinstall the video driver in order to fix this problem (recommended for other users with similar issues), but I currently do not see a Windows 10 version of the driver I need on the Lenovo website.I was wondering:a) if/when a new driver would be available to install (if that's the recommended solution)b) is there something else going on?c) Windows 10 allows you to revert back to Windows 8.1 within the first month of use.  Should I just do this?d) Is the p400 touch capable of running Windows 10? Why or why not?Thank you!

If you look in this list -
https://support.lenovo.com/us/en/documents/ht103535
 
P400 is not listed as a supported system. I doubt it will be supported in the future but you can always call and ask Lenovo directly.
 
Why it is going dim?
This is because of the Chipset or the Intel drivers.
 
What you can do to make it functional?
- Try uninstalling the chipset and Intel drivers --- Restart --- Let drivers install automatically and check.
These can be uninstalled from "Device Manager" and "Programs & Features" in Control Panel
 
- Revert back to windows 8.1 (This option may or may not work - Did not work on my system)
- Reset laptop to factory settings
 
good luck.
