Thanks for the post, MeatWar.
To preface, we need a machine that can be moved around and, more importantly, be run via a dedicated Win XP SP3 x86 OS. We purchased a mint condition 2013 Dell Precision M4700 Mobile Workstation for this purpose that came to us with a working SATA III SSD with a fully-functional version of Win 11 installed.
As a MacBook Pro (MBP) user for the past 15+ years, I mistakenly assumed that I could make a bootable clone copy of the SSD that came with this machine. Eventually, I used Macrium Reflect to make a clone copy on an attached external USB drive, but the problems started when I attempted to verify the copy the same way I’ve done numerous times with our MBPs.
Specifically, I kept the external USB (clone copy) drive connected to the M4700 and posted to BIOS to change the boot order/priority to boot from said external USB drive. As the external USB drive wasn’t detected by the M4700’s BIOS, I employed a search button/control to search for a path to the clone copy. After finding a reference to the external USB drive, I saved it at the top of the boot sequence list and attempted to boot from it.
Very long story short, I ended up with an M4700 that would no longer display video - and I know that it wasn’t a display failure because the display passes its built-in diagnostic test every time I run it. After testing all four 4GB SODIMM RAM modules and the dGPU card that came with the M4700, we decided to replace the main board and the dGPU card (to add nVidia Optimus functionality), with both taking a lot longer than anticipated to arrive.
Fast forward to the original motherboard (mobo) and dGPU card finally being replaced - on a fully ESD safe work mat - and we had a brand new issue. This time around, the M4700 will start, both fans will run at full RPM and, after roughly 3-4 seconds have passed, the machine will shut itself down.
Shortly thereafter, the three diagnostic status LEDs above the keyboard (top-left) come on in the following sequence: Storage LED Solid-ON | Power LED Blinking ON-OFF | Wireless LED Solid-ON. According to Pg 68 of the M4700 Owner’s Manual, this LED status is a fault indication that, “The memory modules are detected but have encountered an error.”
As I mentioned before, all four SODIMMs that came with this machine had been tested, but, due to the fact that the machine consistently indicates a RAM fault, I ordered a pair of Crucial 8GB DDR3L-1600 SODIMM RAM modules, but despite having installed the new RAM in each of the four RAM slots on the replacement mobo, we still experience the same exact symptoms and LED fault indication.
At this point, I’m simply reaching out to anyone out there who’s worked on one of these machines and experienced any of the problems that I’ve described. Needless to say, I’d be very grateful for any help I can get.
EDIT: I recalled a couple of things that I forgot to mention in my last. First, the CPU is a 3rd Gen Intel Core i-7 3940XM (Quad Core). It is one of the only active components in this machine that hasn’t been replaced [yet]. Also, we’ve been told that running Win XP x86, via a VM in a newer OS, will not work with the [very expensive] x86 legacy utility we purchased this machine to run.
Thank you kindly for your time -
