SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (fastboot.sys)

Hi,

 

I am having a Lenovo Twist S230u laptop. It is the most comfortable laptop I ever had except it has this one issue. Whenever, I work on the thinkpad, all of a sudden the BSOD appears with the message "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (fastboot.sys)". Once restarted, everything works fine. But, this issue occurs frequently Smiley Sad I did search through the internet, but I cannot find any issues related to fastboot.sys. Please help.

 

Thanks in advance.

 

Regards,

Siva

Re: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (fastboot.sys)

Hello,

 

I don't recall seeing a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED in FASTBOOT.SYS error message before on a ThinkPad S230.

 

A few things to check, in no particular (or at least, very rough) order::

 

  • First off, back up any important data off the S230u.  It's not that we're doing anything particularly risky, but that's such an uncommon error, I want make sure you have your valuable data saved off somewhere in case there's a problem.
  • Disable hibernation on the computer by opening an elevated Command Prompt (filename: CMD.EXE) and issuing a "POWERCFG.EXE -H OFF" command at the command prompt, then restart the system.
  • Check the boot drive for errors by opening an elevated Command Prompt (filename: CMD.EXE) and issuing a "CHKDSK.EXE C: /B" command at the command prompt.  You will need to restart the system so the disk check can occur, and it may take some time to complete.
  • Run the Lenovo ThinkVantage System Update utility and make sure all the device drivers and ThinkVantage software are up to date.
  • Run Windows Update and make sure the operating system is fully up-to-date, including any optional updates, hotfixes, etc.

If no errors occur for a few days after performing these activities, go ahead and re-enable hibernation by opening an elevated Command Prompt (filename: CMD.EXE) and issuing a "POWERCFG.EXE -H ON" command at the command prompt, then restarting the system.

Thanks Aryeh,

BTW, may I know how long will the check disk for error will take? For me it is stuck at 11% for the past 30 mins. Is this normal?

 

Re: Now the CHKDSK is over. I will wait for couple of days to see if the issue is resolved. Thx

Re: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (fastboot.sys)

Hello,

 

The amount of time it takes for a ChkDsk to finish varies greatly depending upon the speed of the drive, amount of files on it, size of the files, and how spread out they are (fragmented) across the disk.  In some cases, it can be about an hour (fast, mostly empty drive).  In worse cases (slow, external, very full drive) it can take over a day.

 

Regards,
