I know less than nothing about Dell venue 11's, but an internet search offers quite a lot....
The “vibrating but black screen” on a Dell Venue 11 Pro is almost always a firmware/EC hang or a display‑backlight failure, not a completely dead mainboard. The most reliable fix reported by multiple owners is a full power drain with battery and CMOS disconnected, followed by a BIOS reflash if it boots. dell+1
Quick checks (1–2 minutes)
Do these first to narrow it down:
Hard reset: hold the power button for 45–60 seconds with the charger plugged in, then release and try powering on normally. dell
LCD self‑test / BIST: on many Venue tablets you can trigger a built‑in display test by holding Power + Volume Up (or sometimes just long‑pressing power) from off; you should see a colour cycle or pattern if the panel and backlight are OK. If that works but Windows doesn’t display, it points to drivers/firmware rather than hardware. dell
External monitor (if you have a dock or USB‑C/HDMI adapter): if an external display works while the internal is black, that again points to the internal panel/backlight or its cable rather than the mainboard. dell
If the hard reset alone doesn’t help, the next step is the “battery + CMOS drain” procedure that has fixed this exact symptom for many 7130/7140 units. dell
Proven fix: full power drain (battery + CMOS)
This is the method that repeatedly resolves “vibrates once, then black screen” on Venue 11 Pro 7130/7140. dell
Caution: this involves opening the tablet. If you’re not comfortable with that, get a local repair shop to do it.
Power off and unplug the charger.
Remove the rear cover
Take out the small side screw, then gently pry off the back cover. dell
Disconnect the main battery from the motherboard.
On some models the battery is screwed to the frame; you don’t need to remove it, just unplug the connector. dell
Disconnect the CMOS (RTC) battery
This is a small twin‑wire connector on the board; it’s a horizontal slide/unclip, not a straight pull. Be gentle. dell
Optional but recommended: if you can easily access them, also unplug the display ribbon cables and any other ribbon cables under the main battery, and remove the SSD if fitted. dell
Drain residual charge
With everything disconnected, hold the power button for 60 seconds.
Leave the tablet like this for at least 1–3 hours (overnight is even better). dell
Reassemble
Reconnect the display ribbon(s), SSD (if removed), CMOS battery, then main battery.
Replace the back cover and screw.
Power on
Plug in the charger and press power. First boot may be slow; allow it time. dell
Many users report that after this sequence the tablet boots normally again, often with the black‑screen/vibration loop gone. dell
If it now boots: stabilise with firmware updates
Once you’re back in:
Update all firmware/BIOS from Dell’s support site for your exact model (Venue 11 Pro 7130/7139/7140). These tablets had several BIOS/UEFI fixes that address black‑screen and sleep/wake issues. dell
Update Intel graphics driver:
Either via Dell’s driver pack for Windows 10/11, or pull the latest Intel HD Graphics driver from Intel/Dell.
If you previously had intermittent black screens after sleep, some users fixed it by uninstalling the Intel video driver with the “delete driver” option, then reinstalling a clean version. dell
Avoid using the battery keyboard dock during initial testing; some threads link dock firmware/power interactions to random black screens. dell+1
If the screen stays black but the tablet seems on
If after the full drain:
You still get one vibration and then black, but:
The LCD self‑test colours do not appear, and
An external monitor also shows nothing,
then possibilities are:
Failed backlight or inverter circuit on the panel.
Loose/damaged display ribbon cable.
Mainboard GPU/display controller fault.
In that case, the next steps are hardware‑level:
Reseat or replace the display ribbon cable.
Test with a known‑good LCD panel if you have one.
If external display also fails and the tablet otherwise powers (fans/LEDs, vibration), suspect the mainboard and consider replacement or professional repair. dell
