Issue:
Windwos 7 x64 hangs on logo screen, but it starts in Safe Mode

Detailed Description:
I purchased my W520 in November, 2011 with 1 year warranty and used it without issues until March 20, 2013. That morning when I started the laptop, it loaded Windows 7 Pro x64, I logged in. After loading the desktop, I locked the screen/user and stepped out for a minute. When I came back, the screen was frozen and after a few minutes of waiting I manually powered off the laptop.

Upon restart, Windows 7 would hang on the logo screen and restart in a few minutes. I was able to restart under Safe Mode, however, which enabled me to create the rescue DVD's.

I decided to re-install the OS, but the installation would hang on the Windows logo screen again. This was also attempted with all accessories (usb kbd, usb wireless mouse, and display I also tried w/o the battery) disconnected. Then I thought, that it could be a bad hdd - I tried installing XP Pro but got the BSOD with a bad hdd error code 0x0000007B. At that point, I attached the hdd to a working PC and ran checkdisk which found no errors. The problem persisted even with unpartitioned disk and a spare hdd that I had on hand. What intrigued me was that no linux live CD could load (it would freeze on the loading screen).

After this, I flashed the BIOS to the newest version without any issues during the flash process. The Windows 7 Pro x64 installation would hang again at the usual logo screen. I also tried with different DVD source... Memtest did not show any problems either. The Lenovo UEFI diagnostics boot cd did not find any issues as well.

Then I called an IT support guy who was not experienced with the issue and took the laptop for bench testing, and after four days of back and forth the IT company was inconclusive that the issues is most likely caused by a bad BIOS.

This happened on March 20, 2013 after Windows 7 installed updates (not sure if this could be related). The weird part is that the W520 worked fine for a year and four months and when it crashed I was able to use Safe Mode, access and flash BIOS, but was unable to run new installation or live CD's.

I disconnected the bios battery and the Win installation was able to fully load the logo screen, but still hung there. No live CD's were able to load as well. I also disabled the discrete graphics with no success though. Disabling different and all peripherals did not make any difference either (I was unable to find a specific menu for the sound device).

Then I decided to install Win XP (under legacy boot). I did not install the drivers on XP but launched the Win 7 installation instead and it froze on the logo screen again. The issue seems to be either a UEFI setting.

The W520 already has the newest BIOS version. After loading setup defaults in the BIOS menu, I changed the display settings to discrete and os detection of optimus to disabled, UEFI boot only but the Win 7 installation would hang on the logo screen. I was able to install Win XP under legacy.

Since none of the above worked, I installed Win 7 on the hdd using a PC. Windows boot would freeze on the logo screen, but would start in Safe Mode. I tried starting in Normal after disabling all services in msconfig (services and startup tabs) without success. I also changed the Regedit value of HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci from 3 to 0 per http://support.microsoft.com/KB/922976.

By the way, I am currently booting in legacy BIOS (either Both with Legacy First or Legacy Only) as UEFI Only would bring up the F12 boot menu and would not boot from CD or HDD (it would not accept any selection entries). My SATA mode in Compatibility. Changing to AHCI did not help based on http://support.microsoft.com/KB/922976.

What do I need to start Win 7 x64 in Normal mode? Legacy or UEFI, SATA in AHCI or in Compatibility mode?

Is it posssible that the UEFI capability could be corrupted?

Is there anything that I am missing? Has anyone had the same experience? What is the conclusion according to you - it is really bad BIOS chip or just a UEFI-related setting?

    Had the Same Issue, solved by removing Intel Rapid Storage Technology.

    Thank you for your post! I tried re-installing Win7 x64 which, I assume, doesn't have Intel Rapid Storage Technology installed; the issue persisted. Only Windows XP could run on this laptop which leads me to think that there could be a UEFI controller malfunction. Thoughts?
  3. If the Intel Rapid Storage Technology is the cause. I think I remember an option to disable it in the BIOS. Maybe try that or just remove the drivers in safe mode.
  4. So you successfully installed Windows? Just can't get to the log in screen? I thought the installation would hang just as it was loading the files.
  5. Note that there are Mobo Driver CD/Media which includes the driver for Intel Rapid Storage Technology. Please make sure to check your Mobo Driver.
  6. If you're issue is on loading the the Windows 7 try using a new DVD Media.
  7. I had what sounds like the identical problem. Safe mode fine, XP fine, Win 7 would lock up before, during, or shortly after login. IBM had me try a new hard drive and clean Windows install, but no luck. All Lenovo diag utilities said everything was fine. The solution was for IBM to replace the motherboard.
  8. I'm having an identical issue on a 5 year old HP laptop. Yep, 5 years after executing like clockwork the system freezes at the login screen. Code39 said the IBM replaced his MOBO, I don't have that option anymore! Color me frustrated.
