Troubleshooting reference
Start with symptoms, rule out homeowner-safe basics, and escalate conservatively when safety, structure, utility service, or water damage is involved.
Call soon
Computer will not boot and has important data
Likely causes
- Drive failure
- Corrupt OS
- Power or motherboard fault
Homeowner-safe check
Stop repeated power cycling if the drive clicks; do not reinstall the OS before backup assessment.
When to call
Call soon for data-first diagnosis, especially photos, tax files, or business records.
Emergency
Laptop or phone battery swells
Likely causes
- Lithium battery failure
- Overheating
- Age or charging defect
Homeowner-safe check
Power down, unplug, keep away from heat, and do not puncture or press the device closed.
When to call
Call or visit a repair shop immediately for safe battery replacement/disposal.
Call soon
Pop-ups claim infection or demand gift cards/crypto
Likely causes
- Scam browser notification
- Remote-access fraud
- Adware or malicious extension
Homeowner-safe check
Disconnect internet and do not call the number or pay; preserve screenshots.
When to call
Call a trusted tech if remote access was granted, money was sent, or banking passwords were entered.
Routine
Device overheats or shuts down under load
Likely causes
- Dust-clogged cooling
- Failed fan
- Thermal paste or battery issue
Homeowner-safe check
Back up data, use on a hard surface, and stop using if smell or swelling appears.
When to call
Call routinely for cleaning, fan replacement, or thermal service before board damage.
Routine
Wi-Fi is slow in parts of the house
Likely causes
- Router placement
- Interference
- Mesh/backhaul limitation
Homeowner-safe check
Restart modem/router and test speed by wire near the modem before buying extenders.
When to call
Call routinely for mesh placement, cabling, or ISP equipment diagnosis.
Routine
Screen is cracked but device still works
Likely causes
- Impact damage
- Digitizer failure beginning
- Glass shards risking cables
Homeowner-safe check
Back up immediately and avoid moisture; tape only to contain glass, not as a repair.
When to call
Call for quote if the model has parts support and repair is less than replacement value.
Call soon
Liquid spilled on keyboard or device
Likely causes
- Corrosion risk
- Shorted keyboard/board
- Battery or charging-circuit damage
Homeowner-safe check
Power off, unplug, keep it open, and do not use rice or heat.
When to call
Call same day for board cleaning if the device or data matters.
Routine
Printer will not connect or prints streaks
Likely causes
- Driver/network issue
- Clogged printhead
- Low-quality cartridge or toner drum
Homeowner-safe check
Run built-in cleaning once or twice and confirm the printer IP/network before reinstalling everything.
When to call
Call routinely if it serves a home office or repeated cartridges do not fix quality.
Routine
Smart home cameras, locks, or thermostats stop responding
Likely causes
- Wi-Fi credential change
- Cloud account issue
- Low-voltage power or transformer problem
Homeowner-safe check
Check batteries and account login; avoid factory reset until ownership/cloud status is known.
When to call
Call if wiring, door hardware, or security monitoring is involved.
Routine
Repair quote requires device password with no privacy process
Likely causes
- Poor shop controls
- Unnecessary full access
- Data privacy risk
Homeowner-safe check
Ask for guest account, written privacy policy, and data handling before leaving the device.
When to call
Call another shop if they cannot explain access needs and chain of custody.
Maintenance schedule
Seasonal tasks
Spring
- In spring, clean dust from accessible vents and confirm laptops sit on hard surfaces when doing sustained workloads.
Summer
- Before travel season, verify cloud backup status, device-tracking settings, two-factor recovery codes, and charger condition.
Fall
- In fall, update operating systems, browsers, routers, and printer firmware before school or remote-work demand spikes.
Winter
- During winter shipping and gift setup, inspect lithium batteries for swelling before charging old phones, tablets, or game devices.
Interval tasks
Monthly
- Monthly, check backup completion, antivirus or security status, storage health alerts, and unusual account-login emails.
Annual
- Yearly, inventory serial numbers, purchase dates, warranty status, recovery keys, and which devices hold irreplaceable files.
Every few years
- Every few years, replace aging backup drives, retire unsupported routers, and plan battery service before swelling damages screens or trackpads.
Cost components
Labor
A realistic labor line covers diagnostic bench time, data protection, disassembly complexity, board-level skill, software cleanup, travel, and user training/documentation, then adjusts for bench diagnostics, data handling, board-level work, calibration, parts sourcing, and privacy controls.
Materials
Material pricing should call out screens, batteries, keyboards, logic boards, ports, fans, drives, adhesives, thermal materials, and network gear; the baseline remains batteries, screens, drives, RAM, keyboards, chargers, fans, thermal materials, network gear, cables, and licensed software where needed.
Permits and inspections
Do not leave permitting vague when the scope includes data recovery, e-waste, warranty authorization, and commercial network work. Inspection ownership affects schedule.
Broad range discipline
The range changes at quick part replacement, board repair, data recovery, and device replacement. Tune-ups and setup are modest; screens, batteries, and drives are mid-range; board repair and data recovery can exceed device replacement but may save irreplaceable data.
What moves price
Pushes price up
- Data recovery priority; added cost is usually tied to bench diagnostics
- Soldered/serialized parts; added cost is usually tied to data handling
- Expedited or in-home service; added cost is usually tied to board-level work
- Business downtime/security incident; added cost is usually tied to calibration
Can reduce price
- Recent backup; lower pricing is likelier when screens is clearly defined
- Clear error codes and model; lower pricing is likelier when batteries is clearly defined
- Common modular parts; lower pricing is likelier when keyboards is clearly defined
- Drop-off instead of travel; lower pricing is likelier when logic boards is clearly defined
Hiring red flags
- The written scope cannot point to device password requested without a privacy or data-access policy when challenged.
- There is no measurable way in the proposal to verify backup and data-loss risk before opening the device.
- The bargain price omits board repair, battery handling, or liquid-damage cleaning steps before any photo record exists.
- Post-job coverage is vague about parts grade, diagnostic fee, and no-fix/no-fee terms and return timing.
- Requests full passwords without privacy policy or guest-account option.
- Uses scare tactics to sell subscriptions after a pop-up scam.
- No no-fix/no-fee or diagnostic policy.
- Cannot explain data backup before repair/reinstall.
Contract checklist
- Device model, serial, condition photos, passcode handling, data backup status, and privacy boundaries with brands, sizes, locations, and exclusions.
- Diagnostic fee, estimate approval threshold, no-fix terms, bench time, and return of unrepaired devices before work starts, including who schedules inspections.
- Part grade, source, calibration needs, water-resistance loss, soldering scope, and cosmetic expectations for access, protection, cleanup, and disposal.
- Data recovery limits, encryption keys, malware cleanup steps, account recovery, and chain of custody as unit pricing or written allowances.
- Turnaround, loaner or shipping rules, warranty on parts and labor, and recycled battery or e-waste handling; final acceptance includes photos, manuals, warranty entries, and lien-release records.
- Device make/model/serial, symptoms, data priority, and backup status.
- Diagnostic fee, repair cap, no-fix policy, and parts/labor warranty.
- Data privacy, password handling, chain of custody, and disposal/wipe policy.
- Part quality: OEM, refurbished, aftermarket, or donor part clearly labeled.
- Return condition, setup, updates, and user handoff/training included.
Warranty norms
Electronics repair warranties usually cover the replaced part and the labor tied to that repair, not unrelated failures on aging devices. Liquid damage, prior board work, swollen batteries, drops, data loss, malware reinfection, and loss of factory water resistance need explicit exclusions.
