Laptop reboots randomly

I have a Dell Latitude E6540 laptop running Windows 7 Pro 64bit that will reboot randomly at night when not in use.  

I saw this in Event Viewer:
   Event ID 55 error: "Event ID 55 Ntfs the File System Structure on the Disk is Corrupt and Unusable. Please run the chkdsk utility on the volume 'drive_letter':."
I found this on Dell's website:
  Issue: Event ID 55 error: "Event ID 55 Ntfs the File System Structure on the Disk is Corrupt and Unusable. Please run the chkdsk utility on the volume 'drive_letter':." appears in the System event log.


1. Ensure the disk controller firmware and drivers are current.

 2. Ensure any third-party storage drivers and firmware are up to date.

 3. Run chkdsk preferably from a bootable USB key.

How do I check the disk controller firmware and drivers versions?  Also, any suggestions on what may be causing the reboot?

Run chckdsk first. Only after it's not solving this reboot problem do you continue searching (option is to replace hard disk)

I agree, run chkdsk if it doesn't resolve the issue backup your data and replace the hard drive. In fact I would recommend backing up the data regardless if it works after chkdsk or not.

Should I run chkdsk /r from the command prompt or run a disk check from C drive, properties, tools, check now?

Before running chkdsk, run the HD manufacturer's diagnostic utility on the Disk. If the disk is bad, chkdsk can cause more issues. If the diagnostic tool of the HD returns that the disk is fine, then run chkdsk. You need to do that from an elevated CMD prompt, and the PC needs to reboot to run the tool.

The disk diagnostics can be found on the UBCD:

If the diagnostic shows the disk to be bad, you will have to replace it.

i recommend going to start > run > type cmd > right click the CMD icon and select run as Administrator

Within the CMD window, type chkdsk /r

It will ask to start checkdisk at next startup.

If you are certain it's a hardware issue, it makes more sense to start copying important data to an external or removable drive. Any more reads / writes to your current HDD will just increase the likelihood of failures.
Aynsley WatsonCommented:
It is possible that the reboots are what has caused the issue with the hard drive, too many unprompted shut downs can cause issues with a hard drive like a corrupt partition or bad sectors. It is possible that something else is causing the reboots, check the system logs to see what happens just before it shuts down.
I agree run the built in diagnostics.

Power-on the computer.
As the computer boots, press the <F12> key as the Dell logo appears.
On the boot menu screen, select the Diagnostics option.
The Enhanced Pre-boot System Assessment window is displayed, listing all devices detected in the computer. The
diagnostics starts running the tests on all the detected devices.
If you wish to run a diagnostic test on a specific device, press <Esc> and click Yes to stop the diagnostic test.
Select the device from the left pane and click Run Tests.
If there are any issues, error codes are displayed.
Note the error code and post back.
No, not the Dell diags. Those aren't as good as the disk manufacturer's diags. Also memtest86+ is a good diag to run and included on the UBCD.
i agree with Rindi here to use the manufacturer's diags
if these run ok - your disk is operating fine, and also the controller and cables and connectors

when this is ok - THEN run chkdsk (which is not a disk checking tool - but a File System check and repair tool)
cja - would you please post what the outcome was? or the fix?

I will post it when I get the laptop back to me.  User is out of office for a few weeks.

well  - i don't understand why you closed the Q yet; you could have waited till then
cja-tech-guyAuthor Commented:
If I wait to long to close the question, I get an email saying "you have and open question"  


yes - but that does not matter
cja-tech-guyAuthor Commented:
OK.  Next time I will leave the question open.
