First let me explain that I have little technical skill. I have used by laptop for 2 or 3 years fine. A week ago it started to intermittently NOT START. I mean nothing. No response to start button -- even battery charge led won't come on. After fussing around with reset button, etc and hitting start button frequently it came on a few times. Now nothing with all combinations of battery only, wall power supply only, etc. A friend of mine who is quite knowledgeable says Mother Board problems.

I would appreciate your input. Thanks, Roy

A short, practical troubleshooting checklist for , building on 's point that simple checks are worth trying first. These steps are ordered so a non-tech shop or friend can follow them and report back precise findings (useful when deciding whether a board-level repair is needed).

First things to have checked or to try at home: verify the AC adapter actually produces the voltage shown on its label (a meter or a shop can do this). If possible, try a known-good compatible adapter so the supply is ruled out. If the adapter is OK, ask a technician to check for voltage at the laptop’s DC-in pads/rails—if there is no rail voltage the problem is happening before the board’s power regulators.

If comfortable opening the case, ask someone to inspect around the DC jack and the small SMD fuse near it: look for loose solder, burn marks, or obvious capacitor damage. A simple continuity test of that fuse and a check for cracked solder joints on nearby components are low-cost diagnostics; replacing a fuse or the jack is usually far cheaper than a full motherboard swap. Intermittent history often points at cold solder joints or a failing power regulator, which a tech can target without replacing the whole board.

Safety and next steps: always remove battery and unplug mains before opening the machine, avoid static discharge, and take photos before disconnecting connectors. If under warranty contact ASUS support; otherwise get two repair estimates and compare those to the price of a used donor board. For , a quick continuity check of the power-button assembly is a good first pass; for , bring the charger and tell the shop what tests you already tried so they can move quickly to board-level checks.

Before going in that deep check board, etc. for dust/lint contamination, clean as necessary.
Prob. could be just a faulty switch. Over a long period of time switches oxidize(rust), get dirty, burn out, or just plain wear out.
