HP ProBook 430 G6: Why is my laptop not charging?

Sat, 18 Mar 2023 09:44:24 -0700

i have a HP probook 430 g6 and it is turning on fine and working flawlessly except charging the battery. i bought and installed a new battery and it can run on the battery power that came in the new battery but it wont charge at all (i've tried using both the dc power jack and the usb c for charging). i did already try all of the software solutions i could find online without success like holding the power button down for 15 - 30 seconds and deleting the windows driver for the battery. it still doesn't charge it shows an orange light and it looks like it is charging but no incoming power is reaching the battery. does anyone know how to (attempt to) fix this problem?

HP ProBook 450 G2: ssd usage pinned at 100 percent with 0.1Mbps/sec

Fri, 17 Nov 2023 07:45:07 -0700

ok let me start from beggining. before upgrading to a ssd i had no problems at all, then i upgraded to m.2 sata 3 ssd ( kingstone brand ) and the problem started. when booting up ( doesn't matter if plugged in or not ) there is a random chance that it does not boot up ( goes to a weird gray screen ) and after multiple hard resets it boots up to windows and there is the second problem, there is chance that pc is not responsive and after trying so hard to open task manager it says disk 100% 0.1Mbps/sec . i have tried multiple windows installs with forcefully not installing new drivers, still the same issue. when it works it works fine.

this is the closest photo i have found about the ssd and this a 120G one mine is 256 and

this is my ssd ( i cant remove the sticker its warranty ) i could not find any information on its speed sadly

HP ProBook 450 G2: Probook G2 not switching on the normal way

Tue, 01 Jun 2021 02:29:35 -0700

Hi my laptop is not switching on the normal way and its also not charging when its off. If you remove the battery and insert the charger it only shows lights on charger, power button, wifi and speaker. These lights just appear for 1 or 2 seconds when inserting charger also when inserting battery. So i managed to figure out how to switch it on when the battery is half inserted. But u have to be quick so that when it flashed those lights when inserting the battery u switch it on. But on charger it doesnt switch on. When the battery is fully inserted it doesn't switch on. If u switch on it works perfectly and it charges the battery. But u cant switch it on the normal way

I have tried to press power button for 1min but it doesnt help. I also watched a video that was talking about falty keyboard, i tried to remove the keyboard but it didn't work. I tried changing RAMs, and changing the charger but it didn't help

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 445 G8: Black screen and blinking Caps-lock

Thu, 23 Apr 2026 23:24:21 -0700

I have an HP ProBook 445 G8 from 2021 or 2022 running Windows 11. I've ran into an issue where the system won't boot, instead giving me a black screen, the light of the F5-key (mute) is on and the Caps-lock key blinks 5 times slow, then the fans start audibly spinning.

I have already tried putting the RAM stick in the other slot (a friend of mine with the same system had a similar issue when the RAM turned out to be loose) but to no avail. It also sometimes does boot (I haven't found a pattern to that) but it doesn't take long for it to cut to black again. Lastly I have found that the laptop will often boot after hitting the left half of the keyboard.

Any advice would be greatly appreciated, thank you very much in advance.
