Hey All,
Just as a preface this was a laptop bought from Amazon Warehouse deals, so it is a used laptop. No idea how long it was used...But the hard drive was brand new per CystalDiskInfo. I'm guessing this laptop was opened but never really used. This is an Inspiron 7559, a pretty common gaming laptop, running Windows 10.
Out of the box this thing was running incredibly sluggish. Even when setting up Windows 10 navigating between pages was taking 10+ seconds for the mouse input to register. I also tried a fresh Windows install just to be sure. The only things currently on the computer are the standard Dell bloatware and a few hardware monitoring tools to diagnose the problem. And when I say slow, I mean opening up windows file explorer or task manager takes 30+ seconds and mouse/keyboard inputs take 10+ seconds. When I hit the wall I do notice that CPU frequency jumps down to 800MHz, assumingly the lowest possible frequency based on the multiplier range.
My temperatures generally sit between 40-60C, but my fans never seem to actually start up. When I updated the BIOS the fans started blasting, so I know they aren't just totally dead.
I've also run multiple hardware tests that say the hard drive, memory, and CPU are fine.
Anyone have any ideas on what could be causing this or any other means of diagnosing the problem? The Dell Diagnostics toolkit was run and the fan test didn't throw any issue, but I don't see any way of controlling the fans to even test whether or not having the fans running on full blast would prevent this.
