The laptop suddenly stopped working. It is plugged in, but the power light on the front panel just blinks. The computer does not boot or start. And yes, I pushed the start button. No other lights on the front panel are lit. Is this a power supply problem
Was the laptop on when it turned off? It may be a PSU problem but we can determine this by removing the battery. Make sure you disconnect the AC adapter while your removing the battery. Inspect the contacts and make sure`there are no black marks or any other dirt. Leave the battery out and plug in your AC adapter. Try the power again.
There are a couple of possibilities in terms of problems that I can suspect so far. Did anything out of the ordinary happen when the computer just stopped working all of the sudden.
1. Battery has failed and short circuited the contacts
2. Power supply failure
3. Motherboard could have failed in style.
4. Power contacts for the AC adapter are damaged.
