Dell Vostro V3750

    I have two of these Vostro V3750 which exhibit the same fault.

    They crash at random, but usually within an hour of power up.

    Installed software:

    Windows 7 Professional 64-bit as provided by Dell
    MS Office 2010 Plus (corporate version)
    AVG 2011

    I have supplied several Vostro V3750 laptops to other clients but with
    slightly different sofware: MS Office 2010 Home & Business (OEM), and
    AVG 2011 now upgraded to AVG 2012. None of these other laptops crash in
    this unexplained fashion

    One machine is now in my workshop, and on Monday had a fresh factory
    re-install. I reported the problem to Dell and yesterday on this
    machine they replaced the motherboard (using the original CPU) and RAM.

    Today (Friday) this machine crashed while I was typing in a password to
    connect to another machine on the LAN. This was in preparation to
    re-install MS Office 2010 Plus which I had removed as part of an
    unrelated issue - so it's unlikely to be a problem with that version of

    The other machine is with the customer, and after a month of use it
    crashed this week - uses says he had just logged in, and it crashed
    part-way through drawing all the icons on the screen.

    I am aware that UltraVNC is not the most modern version so have
    now installed UltraVNC 10962_X64 - but the earlier version is working on
    the other machines I've installed in the last 18 months.

    Has anybody seen anything similar with these Vostro laptops?

    Any other ideas?

    An update for you:

    1) Machine bought September 2011

    Crashes usually happen within a few minutes of power up; sometimes while
    using trackpad.

    Factory re-install 5 March 2012
    Lockup 6 March 2012
    Motherboard replaced under Dell warranty 8 March 2012 but faulty, coin
    cell discharged
    Lockup 9 March 2012
    Factory re-install repeated 13 March 2012
    Motherboard replaced under Dell warranty again 20 March 2012
    Daily use since then
    Lockup today within a minute of power up.

    I have tried to replicate the original user's environment and working
    practise, with: "Standard User" account, Taskbar and Outlook (with 2
    busy email accounts configured) start automatically following login.

    Generally the machine is started from cold (under 20 degrees C). All
    unusual software removed, only things installed are MS Office
    Professional Plus (corporate version) and AVG 2011.

    2) Identical machine bought February 2012

    First failure 5 March 2012
    Locked up 3 times on 15 March 2012 - in quick succession, starting from

    Same software installed - except that this also has Firefox.

    Another update: Dell agreed to take the first machine back for repair in
    their workshop. I sent full information on how to provoke the fault.

    It came back a week later. The report with it says nothing about having
    confirmed that the fault exists; and says only that the motherboard has
    been replaced yet again.

    I have asked specifically for a full technical report explaining the
    cause of the problem and why two replacement motherboards did not cure
    the fault. Dell only say that the replacement motherboard has been
    "fully tested".

    However, the agent did ring and suggest that the field service
    replacement motherboards are not new and are taken from repaired stock.
    If this is indeed the case then Dell need to get their repair and test
    procedures fixed!

    I have the returned machine on test and am waiting for it to fail again.
    If it works OK for 6 weeks I will send back the other machine for repair.

    Meanwhile, I have no confidence in Dell for any future purchases.

    The continuing saga:

    The repaired laptop came back on 18 April. It has been in daily use
    since, on mains power and with an Ethernet cable connecting it to the LAN.

    Yesterday (6 May) I used it on battery power and with the wireless
    connection to the LAN - and almost immediately it failed ..!!!

    In the past it has failed when on mains power and using the Ethernet
    connection, so I don't specifically blame the wireless connection.

    I've asked Dell for my money back. Will let you all know what happens.

    Dell refuse to give me my money back. They have offered to supply an
    alternative model (more expensive if I so choose and pay the
    difference). Not useful since I have now bought a laptop from a
    different manufacturer for that customer; so I have no immediate need
    for a large-screen laptop at present.

    They are offering to collect the second faulty laptop for repair in
    their workshop; but since the first one has failed despite a workshop
    repair I have no confidence that the second will be any more reliable.

    Any ideas for a name of somebody senior in Dell that can authorise a
    full refund?

    A further update:

    The offer to collect the second faulty laptop turned out to be
    conditional upon my re-installing the operating system and waiting until
    the fault recurred.

    So I factory re-installed its operating system at the begining of June,
    and so far it has worked OK. But it hasn't had the everyday use that my
    customer gave it; and the weather is somewhat warmer so it isn't as cold
    when first started in the mornings.

    Another update:

    The Vostro V3750 laptops are no longer available from Dell, yet the
    smaller Vostro laptops are still available. Perhaps this is an
    admission that there is a known problem!

    The second faulty laptop has not yet failed.

    Dell have collected the first faulty laptop, because I have bought some
    other computers (not laptops) from them; and they have promised a credit
    of the full purchase price. I will let you know when that comes through.

    I now (at last) have a credit note from Dell for the purchase price of
    the laptop bought in September 2011.

    The second laptop bought February 2012 is still on test following a
    complete re-install of the operating system in June 2012, and has not
    yet failed.
