Fan running, keyboard lit, caps lock still toggles but nothing shows on the screen. It feels random because there's no error message, just silence from the display.
It isn't random. There are three specific things this points to, each with a different fix and a different cost.
Rule Out the Simple Causes First
- Connect to an external monitor via HDMI - if the external display works, the panel or its cable is the issue, not the motherboard.
- Try a hard reset - hold the power button for 15-20 seconds, disconnect the charger and battery if removable, then restart.
- Check if Caps Lock or Num Lock lights respond to key presses - if yes, the laptop is on and running, confirming this is a display-path issue, not a dead laptop.
The Three Real Causes, Ranked by How Often We See Them
- Loose or faulty RAM - a stick that has shifted or degraded can prevent the display from initialising even though the laptop powers on. Reseating or replacing it often resolves this instantly and is the cheapest fix.
- Damaged display assembly or cable - the panel, backlight, or the cable connecting it to the motherboard has failed. Confirmed if an external monitor works fine.
- Motherboard graphics circuit fault - the most serious and least common cause. The graphics output on the board itself has failed, and this shows up even when using an external display.
The order matters, because the fixes range from a five-minute reseat to a full board-level repair - which is exactly why a diagnostic before ordering any part is non-negotiable here.
How a Pockit Engineer Diagnoses This
- External monitor test to isolate whether the fault is in the display path or the motherboard.
- RAM reseating and testing with a single stick at a time to rule out a bad module.
- Beep code or diagnostic LED check, where the model supports it, to identify board-level faults.
- Based on findings, a confirmed quote for RAM replacement, display assembly replacement, or motherboard repair.
What Each Fix Typically Involves
RAM issues are usually resolved in the same visit for a modest part cost. Display assembly replacement follows the same process as standard laptop screen repair. Motherboard graphics faults follow the motherboard repair process starting at Rs.999, with the final cost confirmed once the exact component fault is identified.
