Lenovo laptop always starts with boot menu after repair - why?

Apologies for me being vague with this post, because the computer is still in the shop.

Weeks ago, I had to bring a family laptop into the shop because it went dead after water was spilled on it.

Laptop was covered under warranty, the hard drive was safe and intact, and the computer works now, but with two exceptions.

One is that the power button doesn't just fire the computer up any more. It has to be held long and hard before it will activate the computer.

The other is that the computer always brings up what I'll call the boot menu - I believe the one with options like starting in safe mode, turning on debugging, booting normally into Windows. After picking boot normally into Windows a normal startup follows - good - but each restart brings up that boot menu. Obviously normally with Windows, once one boots normally, and the session proceeds normally, no more boot menu is seen until something else triggers it.

The computer is still in the shop. 10 year history with the shop, nothing has ever stymied them, but this has. Any ideas? The power button is likely a HW/electrical issue, but the persistent boot menu is I assume software or OS related.

Is this what you are talking about?

Probably, but I never saw the computer, and the issue is now moot. Other problems crept up today with the computer at the shop. It's under warranty, so they're getting me a new one, swapping in the working hard drive from the old one, and moving forward.
