I have a Lifebook A748/TX that just won't boot up. The laptop powers on, but the screen stays blank and I see three lights blinking on the keyboard: the caps lock, num lock, and some other light that blinks at the same speed as the other two. I was just listening to music the last time I used it. I even tried formatting the SSD, but nothing changed since there wasn't important data on it. Has anyone experienced this issue or knows what might be causing it?

It sounds like your laptop is indicating a hardware issue. The blinking lights often point to specific problems depending on the laptop model. You mentioned trying to swap RAM, which is a good move. If that didn’t help, it could be a motherboard issue. Check the blinking codes online for your specific model to see what they might mean. Let's hope it's nothing too serious!

Yeah, definitely check those codes. I had a similar issue and found out it was my motherboard too. Just be prepared for the possibility of needing some repairs!
