    I bought a Lenovo R60e in April and about 4 months ago without any apparent
    reason, the screen would freeze. I don't know if it's a hardware issue or
    caused by a Vista update at some point. This happens randomly. Sometimes
    once a week and sometimes everyday. This is the event log data:

    Log Name: System
    Source: EventLog
    Date: 11/4/2007 4:51:51 PM
    Event ID: 6008
    Task Category: None
    Level: Error
    Keywords: Classic
    User: N/A
    Computer: Thales-PC
    The previous system shutdown at 4:44:30 PM on 11/4/2007 was unexpected.
    Event Xml:
    <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
    <Provider Name="EventLog" />
    <EventID Qualifiers="32768">6008</EventID>
    <TimeCreated SystemTime="2007-11-05T00:51:51.000Z" />
    <Security />
    <Data>4:44:30 PM</Data>


    Any help would be appreciated.
    Thanks so much.

  2. Yiasou, Thales

    NMI is "Non-Maskable Interrupt". It's a distress signal the hardware sends
    to the operating system when something has gone seriously wrong. It is
    "non-maskable" in the sense that nothing can stop this signal from reaching
    the operating system; it is the highest priority message that can be sent.

    This is a hardware error. It may be quite easy to fix, or you may need to
    have the machine replaced. Sometimes just re-seating the memory chips can
    solve the problem. Your best bet will be to contact Lenovo Support and have
    them troubleshoot the problem. There is nothing you can configure in
    Windows, to solve NMI errors.

    Good luck with it,

    Hi Andrew - Geiasou also,
    Thanks for taking the time. That was very much appreciated. I will try
    reseating the memory chip as you suggested. I'm affraid that might void my
    warranty but will risk it anyway! I spoke with Lenovo several times and a
    few said that it's impossible to say weather it's a hardware issue while
    about 5 of the calls I made were an attempt at upgrading BIOS, drivers,
    defrag, and a bunch of other software attempts. I'll give it a shot and let
    you know. Thanks and best greetings from a Cypriot living in Brazil.

    Andrew, just wanted to add one more point. A tech friend suggested I back up
    everything and then restore to the original state. Run the computer for a
    week or so to see if problem appears. If not, keep adding one software at a
    time to see if problem may be affected by the newly installed program. Is
    this a good idea or do you insist that it's probably a hardware "memory"
    issue. Nothing is black or white but based on your experience do you still
    think I should discount it as having anything to do with something I may have
    downloaded, installed or automatically updated over time?
    thanks for sharing your thoughts.

  5. You can also test the memory using Vista's built-in memory test tool. See
    here for steps:

    This will help to show whether there is a physical problem in the memory

    If it was my machine, I would really push hard on Lenovo to investigate the
    problem - if the machine iss still under warranty.

    Reseating the memory chips sometimes works, if the problem is a poor contact
    between the chip and the slot. But there aer many other possible defects
    that could cause NMI errors, which cannot be fixed that easily. Whether it's
    worth voiding your warranty over ... well, I'll leave that to you to judge.

    As you say, it's hard to be black and white; but in my experience this is
    nearly always a hardware problem. If it is caused by software, it would be a
    device driver which is causing some hardware component to misbehave. It
    wouldn't be caused by an application which is running entirey in user-mode
    (eg word processor, web browser, email etc). But going back to a clean
    install, as your friend suggests, is always a good diagnostic
    technique.Especially if Lenovo won't help!!

    Good luck, let us know how you get on.

    ate logo :) or should I say "andio" :))
