HP ProBook 450 G1: Why my pc doesn't start anymore

Mon, 04 May 2026 10:57:28 -0700

My HP ProBook got wet with water and now it won’t turn on. At one point, after cleaning it and letting it dry, it turned on, but the fan wasn’t spinning. Then I checked it again, and after that it stopped turning on completely. Now there are no indicator lights at all, except the one near the charging port

HP ProBook 450 G7: My Fan is trying to start but it's failing

Fri, 24 Apr 2026 10:44:48 -0700

My fan is failing to start it keeps throttling but doesn't start. I tried cleaning it and got a lot of dirt out but I know the dirt wasn't the problem so what is?

I also attempted using wd40 on it but it also didn't help so I think it might be something with the fan or something else maybe.

HP ProBook 450 G6: My laptop won't turn on, but the power button light turns on.

Fri, 09 Jan 2026 05:44:28 -0700

In addition to the issues I mentioned in the title, when I try to turn it on, it makes a loud noise, I think it's the ventilation, and it only stops when I turn it off and i feel some air coming out from the inside. It charges but doesn't open. It's relatively new I've only had it for 2 years. But its battery has never lasted more than 4 hours. Can you help me please? I appreciate it.

HP ProBook 450 G3: Why laptop turn off in light load while power outlet is connected?

Wed, 28 May 2025 02:34:49 -0700

Why does the laptop turn off when running a light load while the power outlet is connected, knowing that if I remove the battery it works normally . Conversely, if I removed the power outlet and used the battery, it works fine.
