LG Gram Pro (17", 2026) randomly crashes with Stop code: VIDEO_MEMORY_MANAGEMENT_INTERNAL (0x10E)

Problem:  As described.  Starts suddenly, disappears just as suddenly.  Crashes can occur anytime after boot (i.e. anywhere between 5 minutes and hours later), or sometimes never.

---

Solution:  Try unplugging devices from the USB-C ports before booting.

If that works, you can try disabling "Fast startup" in the Windows Control Panel and the BIOS, then try again by rebooting with USB devices plugged.

If that doesn't work, the Gram is just not for you.  Return it.

I spent days on this one, and I am thoroughly unimpressed with LG for making me do that.  

Windows updates, driver updates, advanced graphics settings, startup/power settings, BIOS settings, memtest_vulkan, endless reboots.  Hours staring at it, wondering if or when it might crash again.  I had to set up a camera to watch it!

Was totally ready to return the thing, then I unplugged the USB-C-to-Ethernet adapter and shazam - no more crashing.

Immediately thought "bad adapter".  But it worked on another machine, and it worked fine when I plugged in back into the Gram.   Chalked it up to "shit happens".

---

Then the Gram crashed again, this time with a USB-C monitor plugged in.  (Not even a 4k , mind you, just an old 1080p panel.)

So it seems there is a USB-plugging-conflict problem that only occurs at boot, and with any USB peripheral.  

I had replugged the Ethernet adapter after boot, so it was fine.  If I hadn't accidentally run down the battery with the external monitor plugged in, I never would have gotten this far.  Pure luck.

AI suggested wiping drivers with DDR and all other kinds of intricate crap that shouldn't be necessary on >any< brand-new machine, much less one made in ^%$#@!! century.  

Disabling "Fast startup" was my last try.  It didn't work.  

So now I have to decide between keeping a flawed $5000 machine, or returning it and taking a chance on another marque (which has a smaller screen and significantly more expensive).

---

I also have to say that LG Support really shit the bed on this one.  I don't like saying it, but it's true.

I never call tech support, but I finally called them in a last-ditch effort for help.  It was a brand-spanking-new machine, after all.  I'm a customer, I deserve tech support.

I didn't get any.  Their only solution was to do a warranty repair that would require a minimum of two weeks.  

This is after I told them the exact error in the title.

They didn't even attempt to do any basic troubleshooting.  If they had, I might have noticed the Ethernet adapter sooner.

Yes, it is my own fault for not unplugging all the peripherals sooner.  But I defy anyone to decipher VIDEO_MEMORY_MANAGEMENT_INTERNAL (0x10E) to mean "unplug USB peripherals before booting".

Wiring an ecobee3 without the G wire (G-wire, fan wire)

Note: this post has nothing to do with the dreaded "C-wire" that is required to run an ecobee.  If you're looking for that, go elsewhere. One of the more frustrating items for a heating/cooling system is the sheer number of possible ways to set it up.  Sure, there are "standard" ways, but there are also always other ways. We had a new furnace installed not long ago.  However, there were not enough wires run to the thermostat to support the additional A/C system.  The cable had only enough wires for heat-only operation. To make it work, the installers should have run a new cable, but they didn't.  Instead, they disconnected the G (fan) wire, and used it for Y (cold call) instead.  This led to an atypical installation that lacked a G (fan) wire at the thermostat. Note it still worked.  The thermostat sent the W (heat) and Y (cold) signals, and the furnace controlled its own fan.  No worries, thanks to them thar new-fangled furnace, y'all. ...

How to fix Lexus / Toyota "AWD system malfunction 2WD mode engaged"

May be associated with other errors, such as "Check Engine" light, ICS / backup system warning, etc.  Simple fixes that may save you time/money: 1.  Check gas cap is tight. Yes, it's stupid - damn stupid, in fact.  But it worked for me and others . Note the old RX330s had a similar issue, in that it would throw error codes if the gas cap was loose.  Happened to me a few time when the weather got really cold.  It's all because the car is looking for leaks in the emissions control system and sees that the pressure in the gas tank is not holding steady. 2.  If codes do not clear themselves, disconnect battery for 5 min, then reconnect and start. •  Open the door during that 5+ min, to ensure system is fully discharged.  Not needed but can't hurt. •  Yellow ICS light (top right-hand corner on RX350) will flash on restart.  It will self-reset upon driving, don't worry about it. 3.  Recharge battery to full, then retry.  Worked for h...

Hiren's Boot CD HBCD menu missing when booting on Vaio Z3

I wanted to back up my Z3 using Hiren's Boot CD .  I have done this before, and it worked well. (I recommend Image For Windows, available on Hiren's, but you should buy a licence.  IFW seems to be one of the only programs out there that can actually do a bare metal restore.) Oddly enough, when I booted the Z from the USB stick, I did not see Image for Windows.  In fact, I did not see any programs at all.  Mini Windows XP ran fine, but all the programs were missing! Scrounging around the File Manager turned up nada.  It looked like the USB stick was not there, even though the machine had booted from it just fine. The conflict in my case was an SD card that I had added to the system.  It seems Mini XP got confused after boot and replaced the USB stick drive with the SD card.  XP was not capable of reading the SD card owing to the large capacity, and essentially got stuck, unable to locate or load any of the Hiren's apps. Removing the SD card (a...
