Battery swelling, burning smell, or unusual heat
Stop using the computer. Disconnect external power only when that can be done safely, then use the manufacturer or a qualified hardware specialist.

Computer Repair
Computer won’t turn on or boot: is it power, the screen, Windows, or the drive?
A computer that appears dead can have a power, charger, dock, display, Windows startup, storage, or hardware problem. The safest first step is to identify the last reliable clue, protect important data, and choose the right support route without opening the device or starting a destructive reset.
Guide updated
Start with simple checks. Get expert help when the fix needs more.
Power, fan activity, screen output, and where startup stops help separate power, display, Windows, and drive problems.
Start with the last reliable clue
Which of these four startup states matches the computer?
Observe first and change as little as possible. The point is to choose the right support route, not to guess at a repair.
- State 1
Nothing happens
Safe observation: After checking a known-working outlet and the computer’s normal power lead, note any charger light, case light, fan, or startup sound.
Recommended next step: No response usually needs an on-site power-path check, or the manufacturer when warranty coverage applies.
- State 2
Lights or fans, black screen
Safe observation: Note whether the monitor has power, which input is selected, whether a dock or external display changes the result, and any beep or blink pattern.
Recommended next step: Use an on-site display and hardware diagnostic; a remote session cannot start before the computer shows a usable desktop.
- State 3
Logo, loop, or error
Safe observation: Record the exact logo, loop, recovery, or error screen only if it contains no private information or recovery key, then note what changed recently.
Recommended next step: Use a startup or Windows diagnostic; choose the device or organization vendor when warranty or management controls apply.
- State 4
Desktop, then freeze
Safe observation: Note when the freeze begins and whether the computer stays stable long enough to protect current work and confirm an existing backup.
Recommended next step: A stable desktop may allow remote triage; repeated crashes or drive warnings belong on the on-site or data-recovery path.
Stop now
These signs change the job from normal troubleshooting to risk control.
Liquid exposure
Do not power it on again or use heat to dry it. Keep ordinary troubleshooting paused and use the appropriate hardware or manufacturer route.
Clicking or grinding
Stop repeated power-on attempts. If the files matter, ask a data-recovery specialist before normal repair work.
Irreplaceable files with no verified backup
Do not run repair tools, initialize the drive, reset the computer, or reinstall Windows before getting recovery advice.
Choose the right kind of help
Remote, on-site, vendor, and data recovery solve different problems.
Remote
The computer reaches a usable desktop, connects to the internet, and stays stable long enough for an approved session.
On-site
There is no power, a black screen, an early startup loop, a dock or monitor question, or uncertain physical hardware.
Vendor / manufacturer
Warranty, battery swelling, liquid or impact damage, managed business equipment, or specialized hardware work is involved.
Data recovery
A drive clicks, grinds, disappears, or holds irreplaceable unbacked-up data that further testing could put at risk.
Customer-controlled information
Share symptoms, not secrets.
Useful details are the device model, visible lights or sounds, the exact non-sensitive screen, recent changes, and whether an existing backup matters.
Do not send passwords, MFA codes, BitLocker or other recovery keys, private files, or sensitive screenshots.
Nothing here authorizes a reset, reinstall, format, firmware change, drive repair, or opening the device. Diagnosis, recovery planning, and explicit approval come first.

Common symptoms
- Nothing happens: no lights, fan, startup sound, or image appears when you press power.
- Lights or fans start, but the built-in display or monitor stays black.
- A logo appears, then Windows loops, shows an error, opens recovery, or never reaches sign-in.
- The computer reaches sign-in or the desktop, then freezes, crashes, or becomes too unstable to use.
Quick checks
- Stop using the computer if you notice a swollen battery, burning smell, unusual heat, liquid exposure, repeated clicking or grinding, or irreplaceable files with no verified backup. Unplug external power when it is safe to do so and arrange the appropriate professional help.
- If nothing happens, confirm the wall outlet or surge protector works, seat the normal charger or power cable firmly, and disconnect a dock or nonessential accessories. Do not open the case, substitute an incompatible charger, or probe internal power parts.
- If lights or fans start but the screen is black, check brightness, the monitor's power and selected input, and whether a dock or external display is hiding the picture. Record any blink code or beep pattern instead of repeatedly forcing shutdowns.
- If a logo, boot loop, blue screen, Automatic Repair screen, or update message appears, photograph the exact wording or stop code and note what changed recently. Disconnect nonessential USB devices, but do not keep interrupting updates or run a factory reset as a test.
- If the desktop appears and then freezes, protect current work and back up important files while the computer is stable enough. A one-time normal restart may help, but repeated crashes, drive warnings, or worsening behavior need diagnosis before cleanup or upgrades.
- A BitLocker recovery screen is an ownership and encryption checkpoint, not proof that the files are gone. Retrieve the key through the owner's approved Microsoft or organization account on a trusted device; do not send the key through a booking form, text, email, or report.
- A no-boot-device message can mean a setting, connection, failed drive, or storage problem. If the drive is missing, making unusual sounds, or holds irreplaceable unbacked-up data, stop experimenting and ask about data-recovery options before repair attempts.
- Keep passwords, MFA codes, BitLocker or other recovery keys, private files, and sensitive screenshots out of the booking request. Share the device model, lights or sounds, exact last screen, recent changes, backup importance, ZIP code, and preferred time instead.
When to call
- Choose remote triage only if the computer can reach a usable desktop, connect to the internet, and stay stable long enough for an approved diagnostic session.
- Choose an on-site diagnostic when there is no power, a black screen, a dock or monitor question, a startup loop, or uncertainty about which physical component is involved.
- Use the manufacturer, an authorized repair provider, or an appropriate hardware specialist for warranty work, battery swelling, liquid damage, burning smells, cracked hardware, soldering, or board-level repair.
- Ask a data-recovery specialist before normal repair when a drive clicks or grinds, disappears, contains irreplaceable unbacked-up files, or further power-on attempts could reduce recovery chances.

FAQ
Quick answers before booking.
Does a computer that will not boot mean my files are gone?
No. A power, display, update, or Windows startup problem does not automatically mean the storage has failed. Recovery still cannot be guaranteed, so stop repeated testing when the drive makes unusual sounds, disappears, or holds irreplaceable files without a backup.
Can remote support help if the computer will not turn on?
Usually not if the computer cannot reach a stable desktop and internet connection. Remote triage can work when Windows loads and stays usable; no power, black-screen, and early-boot problems usually need an on-site, vendor, or specialist path.
Should I reset Windows from the recovery screen?
Not as a diagnostic shortcut. A reset can remove apps, settings, or data and can make recovery planning harder. First record the exact screen, confirm backup status, and understand whether the problem is Windows, storage, encryption, or hardware.
Can Tech Genie bypass BitLocker or recover a missing key?
No. BitLocker protects the owner's data, and Tech Genie does not bypass encryption or guarantee recovery. The owner or authorized organization must retrieve an available recovery key through its approved Microsoft, work, school, or documented account path.
