HP ProBook 450 G2: How do you clean the fan?

Tue, 01 Jun 2021 07:42:46 -0700

I’ve had my laptop for 4 years now and the fan is always ramped up at max, making it very loud and whinny. I have never cleaned it, but I feel like its about time I did, and get to see if that problem goes away. Thoughts?

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 G2: Laptop switches off automatically

Fri, 14 Jul 2023 13:17:23 -0700

Hi,

I have been facing an issue with my laptop lately, once I switch it on and I start working on it, it somehow switches off automatically and when I start it again, it will start and switch off again and again until I press the metal body beside the trackpad.

thank you
