Learn more →Camera indicator light turns on but display is black — privacy shutter engaged, driver conflict, or camera module hardware failure.
Learn more →Cursor jumps around or drifts across the screen without touching the pad often caused by a worn trackpad, a swollen battery pressing underneath, or outdated drivers.
Learn more →The keyboard backlight stays dark even with the brightness key pressed — a disabled setting, a driver issue, or a faulty backlight ribbon cable.
Learn more →Typing on the main keyboard produces numbers instead of letters, usually because the Num Lock key is toggled on or stuck.
Learn more →Laptop hangs at the brand logo before Windows loads — a failing hard drive or SSD, corrupted boot settings, or a hardware fault preventing startup.
Learn more →The laptop powers on with the fan spinning and power light on, but the screen stays black — a loose display cable, faulty LCD panel, or a RAM or graphics driver issue.
Learn more →Performance drops sharply the moment the charger is unplugged — Windows power saver mode, CPU throttling, or a degraded battery limiting power delivery.
Learn more →The laptop runs only on its weaker built-in graphics because the dedicated GPU has vanished from Device Manager, often after a driver failure, a Windows update, or a hardware fault.
Learn more →The laptop runs hot and the fan never spins up, or it stops and starts erratically — a clogged fan, worn bearing, or faulty fan controller causing overheating and sudden shutdowns.
Learn more →Display blacks out for a moment whenever AC power is connected or removed — often the screen switching refresh rates or a graphics driver glitch, sometimes tied to power plan settings.
Learn more →The charging LED blinks or flashes instead of staying solid and the battery percentage never rises — usually a faulty charger, a damaged charging port, or a battery the laptop has stopped accepting.

Learn more →Pressing the BIOS key (Del, F2, or F10) does nothing and the PC boots straight into Windows — fast boot, a USB device, or a failing keyboard can block the setup screen from appearing.
Learn more →The computer drops into sleep or the screen shuts off while you are still working — usually a power plan setting, an accidental sleep timeout, or a faulty power button.
Learn more →Computer boots to a black screen saying no bootable device found — often a dead or disconnected drive, corrupted boot records, or the wrong boot order preventing Windows from loading.
Learn more →The PC lands in the BIOS or boot menu instead of loading Windows, usually because of a wrong boot order, a failing boot drive, or a corrupted boot loader.
Learn more →The computer shows no power after you cleaned the inside or installed a new component — usually a loose power cable, unseated RAM, or a disconnected front-panel header.
Learn more →Power or activity lights on the case stay dark or blink erratically while the PC runs normally — usually a loose front-panel header connection to the motherboard or a faulty case LED.
Learn more →Beeping sounds when you press the power button usually point to a hardware fault such as bad RAM, a loose graphics card, or a failing motherboard.

Learn more →The ports on the front of the case stop charging or detecting devices even though the rear ports work — typically the front-panel header cable has come loose from the motherboard or the internal hub has failed.
Learn more →PC powers up but the monitor stays in standby after sleep — a common DisplayPort handshake or linked power-saving setting issue, not a dead screen.
Learn more →A PC that worked before the move often has a card, RAM stick or cable knocked loose in transit, so reseating the parts usually brings it back to life.
Learn more →An interrupted BIOS flash leaves the PC dead with no display or beeps — most boards can still be recovered through a USB BIOS flashback port.

Learn more →Screen flickers or pulses only at specific brightness settings, usually a failing backlight inverter or PWM driver issue.
Learn more →The image splits into horizontal lines during fast movement, usually a refresh-rate mismatch between the screen and the graphics card.
Learn more →Part of the desktop is cut off at the screen edges or the picture is larger than the monitor — incorrect scaling or overscan settings in the display or graphics card software.

Learn more →Colored vertical lines running down the display usually mean a loose display cable or a failing screen panel that needs replacement.
Learn more →The monitor used to run at 120Hz or 144Hz but now only offers 60Hz in Windows display settings — usually the graphics driver reverted, the cable cannot carry the bandwidth, or the refresh rate has to be set manually.
Learn more →The monitor displays an 'Out of Range' or signal error instead of Windows — caused by a resolution or refresh rate the panel cannot handle, often after a driver or game update.
Learn more →A MacBook display that is cracked, dark or showing stripes after a knock — usually panel damage, sometimes only a loose display cable.
Learn more →An accidental Ctrl+Alt+arrow hotkey flips the display orientation — turn it back in Display Settings and check for a stuck graphics hotkey.

Learn more →Laptop shuts down instantly when unplugged from the charger, indicating a completely dead battery that can no longer hold any charge and needs replacement.
Learn more →Computer shows no signs of life after a blackout or power cut — no fans, no lights. Often caused by a tripped PSU protection circuit or surge damage.
Learn more →Windows or macOS reports "service recommended" battery warning — reduced runtime and potential swelling risk if ignored.
Learn more →Battery percentage drops steadily then plummets suddenly — worn-out cells causing inaccurate calibration and unexpected shutdowns.
Learn more →Battery loses charge overnight even with the laptop off or asleep usually caused by fast startup, a USB charging port left on, or an ageing battery.
Learn more →Taskbar shows no battery detected even though the laptop runs fine on AC power, usually a loose battery connector, failed cell, or driver issue.
Learn more →Battery percentage barely rises even after hours on charge — a weak charger, background apps, or an ageing battery.
Learn more →Battery level jumps between readings or reports the wrong charge — a miscalibrated battery, ageing cells, or a faulty charging circuit.
Learn more →Charger becomes hot to the touch while charging — a failing adapter, wrong wattage, or a short in the charging circuit that can damage the battery or start a fire.
Learn more →The battery charges only while the laptop is shut down and stops charging once it is switched on — a failing charger, worn charging port, or battery management driver issue.
Learn more →Charging stops at around 80 percent even though the battery still works — often battery protection software, a faulty charging circuit, or a degraded battery cell.
Learn more →Turning the computer on trips the power strip or the room circuit breaker — often a failing power supply drawing excessive current or a short inside the system.
Learn more →The laptop charges from a wall socket but not from a power strip — often an overloaded strip, loose socket contacts, or an adapter unable to draw enough power through the strip.
Learn more →Laptop only runs while plugged in and switches off the moment the charger is removed, meaning the battery has lost its capacity and needs replacement.
Learn more →The battery bulges, the trackpad lifts, or the chassis warps — a swollen lithium-ion battery is a genuine fire risk and must be replaced and disposed of safely, not kept in use.
Learn more →The computer reboots whenever a large appliance switches on — a voltage dip on a shared circuit, which stresses the power supply over time.
Learn more →The UPS alarms constantly and the PC still dies the moment power trips — the internal battery has reached the end of its service life.
Learn more →A worn charger cable can spark, overheat or cut out, and an exposed wire near the plug is a fire risk — replace it rather than taping it up.
Learn more →The adapter plug sparks or only charges when wiggled — a worn wall socket, a damaged plug pin or a loose adapter socket, and a genuine fire risk that should be checked before it is used again.
