Laptop Not Turning On? 7 Things to Check Before Calling a Repair Service in Dhaka

A laptop that refuses to power on is one of the most common calls we get at BAYAS. The good news: more than half of these jobs turn out to be simple — a faulty charger, a discharged battery, a stuck power button, or a loose RAM module. Before you assume the worst and pay for a board-level repair, run through this checklist.

1. Confirm the charger is actually charging

Plug the charger into a different wall outlet and watch for the LED on the brick. If the LED is dim, flickering, or off entirely, your charger is the suspect. Laptop chargers in Dhaka heat conditions tend to fail at the cable bend near the DC plug. Try wiggling the cable — if power flashes in and out, the cable is broken internally.

Best practice: use the original or a manufacturer-rated equivalent. A 65W laptop with a 45W generic charger will charge slowly, throttle, or refuse to power on under load.

2. Drain residual charge

Disconnect the charger. If the battery is removable, take it out. Hold the power button for 30 seconds with no power source. Reconnect the charger only — try to boot. This drains residual charge from capacitors and clears certain stuck states.

3. Listen for fan and beep codes

Press power and listen. A short fan spin followed by silence often points to a RAM seating or detection issue. Repeated beeps in a pattern map to specific POST errors — count the beeps and search the manufacturer site for the meaning. No fan, no LED, no beep usually means a power circuit fault.

4. Try external display

If the laptop powers on (you hear the fan or see a backlight) but the screen stays black, connect an external monitor via HDMI. A working external display points to a screen, ribbon cable, or backlight fault — not a dead motherboard.

5. Reseat the RAM

If you are comfortable opening the laptop and warranty is not a concern, power off, unplug, remove the bottom panel, and reseat the RAM module by ejecting the clips and snapping it back firmly. RAM contact issues are common in older Dhaka laptops due to humidity and dust.

6. Check for swollen battery

A swollen battery can press against the motherboard and cause boot failures. Carefully press the underside of the laptop near the battery — if it feels bulged or the keyboard area is lifted, stop using the device and call BAYAS. Swollen batteries can ignite.

7. Liquid damage history

If your laptop was ever near water, even months ago, intermittent boot failures often appear as latent corrosion takes hold. This is a chip-level repair job — needs ultrasonic cleaning and component-level replacement.

When to call BAYAS

If none of these steps revive your laptop, the fault is likely on the motherboard — power IC, charging circuit, BIOS chip, or PCH. These are repairable at component level, not just by board swap. BAYAS specializes in this work in Dhaka.
