Direct answer
For the Acer Aspire 5 A515 family, internal display, brightness/lid state, graphics path and external monitor should be isolated. First, test brightness, built-in diagnostics and a known external display.
What this covers
- Acer Aspire 5 A515 family (A515 complete suffix required)
- Acer PC; SNID/model suffix determines BIOS, drivers, display, charger and recovery image.
- The specific fault this record addresses: screen is black, blank or flickering
What it does not cover
- ×The same symptom on a different Acer product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The brightness is at minimum
What separates it A completely black screen on a machine that is clearly running and responsive to sound or typing.
How to confirm Press the brightness-up key several times. This sounds trivial and it accounts for a real share of black-screen reports, particularly where a key is stuck or a keyboard shortcut was pressed accidentally.
- 2
The machine is asleep and not waking
What separates it No response to a mouse move, with the power indicator suggesting the machine is on.
How to confirm Press a key rather than moving the mouse, and try the power button briefly. Some machines wake only on a key press.
- 3
Output is being sent to a disconnected external display
What separates it A black internal screen after an external monitor was disconnected, or after undocking.
How to confirm The system may still consider the external display the primary output. Cycling display modes returns it to the internal panel.
- 4
A graphics driver has failed
What separates it A black screen after an update or a driver installation, with the machine otherwise responsive.
How to confirm Safe mode loads a basic display driver and confirms this. See startup-recovery.
- 5
The display cable or panel has failed
What separates it The internal screen stays black while an external display shows the desktop normally.
How to confirm That combination is close to definitive: the system, its graphics and its output are all working, which localises the fault to the panel or the cable feeding it. On a laptop, a cable that fails at a specific lid angle is a common variant.
- 6
The machine is not actually starting
What separates it No fans, no lights, no sound.
How to confirm See will-not-start — this is a different problem.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether an external display shows a picture — this single test separates the panel and its cable from everything upstream.
- Whether the machine is otherwise responsive: sound, keyboard lights, disk activity.
- Whether the screen changes at all with the lid angle, on a laptop.
- What changed immediately before, particularly a graphics driver or system update.
Press the brightness-up key several times
ReversibleIt accounts for a genuine share of black-screen reports and takes two seconds to rule out.
Connect an external display
ReversibleA working external picture with a black internal panel localises the fault to the panel or its cable and rules out everything else.
Cycle the display output mode
ReversibleThe system may still be sending output to a monitor that is no longer connected.
Move the lid slowly through its range and watch for any flicker
ReversibleAn image that appears or flickers at a particular angle points at the display cable rather than the panel.
Boot into safe mode to rule out a graphics driver
ReversibleSafe mode loads a basic display driver, so a working picture there confirms the installed driver as the cause.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- A515 complete suffix required. Acer PC; SNID/model suffix determines BIOS, drivers, display, charger and recovery image.
- Tier — value mainstream (Windows 11)
- An affordable, practical Windows 11 laptop for everyday use — browsing, office, video — with modest performance and often upgradeable RAM/SSD. Value tier, not gaming/creator.
- Everyday performance
- Fine for light multitasking; heavy gaming/creative work will strain it. Free storage and updates keep it responsive; adding RAM/SSD often helps on this upgradeable line.
- Ports
- Usually includes USB-A, HDMI and USB-C — fewer adapters needed.
- Power path
- Internal or removable battery. Every capability that costs current — night vision, higher stream quality, longer recordings, frequent events — is paid for in runtime, so a change in behaviour after a settings change is usually a power consequence rather than a fault. Cold weather reduces usable capacity sharply.
- Symptom boundary
- This record covers Acer Aspire 5 A515 family when it screen is black, blank or flickering. A different symptom on the same hardware, or this symptom on a different Acer product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Stop for cracked glass, visible liquid, or a burning smell, and do not keep opening and closing a lid that produces a flicker — a failing cable can worsen quickly.
Evidence ledger
Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Acer Support publishes this as "Drivers and manuals". Official Acer model lookup, drivers, manuals and repair support. What that article does not carry is the model boundary — it is written for a product line, and A515 complete suffix required is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
Can I upgrade my Acer Aspire 5 to make it faster?+
Often yes — many Aspire 5 models have an accessible RAM slot and an SSD you can enlarge or add, and those two upgrades give the biggest real-world speed boost (more RAM for multitasking, a bigger/faster SSD for responsiveness). Check your exact model's manual for what is upgradeable and the maximum RAM. Power down and follow the guide, or have a technician do it. Otherwise, free storage, trim startup apps, and keep Windows updated for the best speed at this tier.
My screen is black but the computer seems to be on.+
Connect an external monitor. That one test tells you almost everything: if the external display shows your desktop normally, the computer, its graphics and its output are all fine, and the fault is in the internal panel or the cable feeding it. Before that, press the brightness-up key a few times — it accounts for more black screens than people expect.
The screen flickers when I move the lid.+
That points at the display cable rather than the panel. The cable runs through the hinge and flexes every time the lid moves, so it fails there first. It is worth acting on promptly, because opening and closing the lid repeatedly tends to make it worse.
Does this answer apply to every Acer model?+
No. It is scoped to A515 complete suffix required. Acer PC; SNID/model suffix determines BIOS, drivers, display, charger and recovery image.
What should I record before troubleshooting black screen or flicker?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing black screen, flicker. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Stop for cracked/swollen display, heat, sparks or liquid.
