13 inch, 2017 MacBook Pro, MacOS 13.6.9 (22G830)
Suddenly stopped communicating with my external screen, via old fashioned D-SUB cable (tried HDMI but failed, long time ago). Now the D-SUB cable connection seems to have lost sufficient power to keep the screen alive.
I've re-booted, no change.
Is my MacBook on its last legs?
Cheers,
John

Turns out, the problem was a broken charger. I've replaced the charger and also installed a USB-C to HDMI cable replacing the VGA cable. All working fine, charger + cable + $160AUD, rather than a new computer!

that appears to be a 1920 by 1280 display with
Signal Input:
Analog VGA uses a D-shaped three-row SUBminiature 15-pin connector, so the one labeled D-SUB is unambiguously VGA
When they dropped HDMI port, they introduced USB-C ports. Most HDMI adapters should work, but reliable ones like the Apple adapter are PRICEY, US$70. The cable required can't be any old dusty cable from behind the TV set -- it needs to be a certified Premium cable for this use.
There does not appear to be a DVI - that appears to be a [full size] DisplayPort connector, and your best bet for success. USB-C to DisplayPort adapter/cables are readily available for cheap and not much trouble (below about 4K resolution where things start to get dicey).
What is this D-Sub cable of which you speak? what inputs, what brand?
what resolution is the display? what make&model?
MacBook Pro 13-in 2017 model does not have a built-in HDMI port either. What adapter/cables did you try? HDMI faster than TV sets requires substantial Black Magic to get working.
When the MacBook is open, the external screen is active, but the MacBook's screen is locked onto the last image it showed when the external screen was disconnected. The screen cursor is totally absent though both MacBook trackpad and external trackpad operate the cursor on the external screen. Weird?
By the way, I had to replace the computer's battery, an Apple replacement, a few years ago, and now it sometimes fails to recharge when plugged in. Maybe this is another symptom of a failing MacBook.
