1. The button is failing. Replace it.
2. A relic of a laptop from 2006, my Dell Inspiron would or would not power up when pressing the power button. There was a BIOS update and checking mine it was way out of date. Given the machine's age, I tried that. All better.
Dell inspiron 531s desktop..The start button on my 531s suddenly doesn't want to work. By pressing on the start button over & over, it will usually power up. Once the blue start button lights up, the computer will run forever normally.Unfortunately, due to power outages, etc, the computer is shut down. Only after many pressings of the start button, will the computer boot up. Any ideas ??
