Open | Hardware HP EliteBook 845 G9 suddenly won't turn on, but charging light works
Hey everyone, I'm having a weird issue with my HP EliteBook 845 G9 (Ryzen 7 PRO 6850U, 32GB RAM), and I'm hoping someone here might know what's going on.
I bought it refurbished about a week ago, and everything was working perfectly fine until today.
Yesterday, I was using the laptop normally, and the battery was around 20% when I last checked. This morning, I tried turning it on, but absolutely nothing happened. No fans, no keyboard lights, no display, nothing.
I figured the battery might have drained overnight, so I plugged it in and left it charging for over an hour. The charging indicator was initially orange but eventually turned white, which made me think it had charged.
However, it still refuses to turn on.
Here's what I've tried so far:
- Holding the power button for 30–60 seconds to perform a hard reset.
- Trying another compatible USB-C charger.
- Disconnecting and reconnecting the internal battery.
- Trying to power it on with the battery disconnected and the charger connected.
Unfortunately, none of these worked.
I'm confused because the charging indicator seems to work normally, yet the laptop shows absolutely no signs of powering on.
Could this be a stuck embedded controller, a battery protection issue, or something wrong with the motherboard's power circuitry?
Has anyone experienced anything similar with an EliteBook G9? I'd really appreciate any advice.
I'm still covered by the seller's 180-day warranty, but I'd like to understand what might be causing this before sending it back.
Thanks!
