Testing battery on a Dell laptop
April 11, 2024 at

I just purchased a refurbished Dell Latitude laptop and i remember reading about testing the battery when I'd arrives and if needs updated they contacted Dell for a replacement.
Just wondering how to test the battery? Is there a n application that can do this?

I'm assuming this is not an issue and no need to Contact Dell asking for a new battery?

Dell Refurbished batteries are supposed to have 80% of their design capacity remaining. Dell Refurbished often ships them with far less than that. Additionally, use your computer intensively for the first 2 weeks, as even if it's over 80% of design capacity initially, I've seen them drop a lot in just 2 weeks. Run a battery report after the first 2 weeks, too.

Windows 11 causes all kinds of hard-to-diagnose conflict with drivers which can cause your computer to randomly shut down. I've been troubleshooting a relative's computer for the last 2 weeks and still haven't gotten to the bottom of it. My advice is to not upgrade to Windows 11 if you can avoid it. If you do upgrade and start getting sudden shutdowns, update all your drivers at Dell. Update your BIOS (back up computer first & create a restore point).
The shutdowns may involve blue screens of death (BSODs), but they can also involve your computer's screen going black suddenly - but the LED on the power light may remain on (if this happens, you may have to hold the power button down for about 10 seconds to shut computer down, then reboot - you'll lose work you had open). There are all sort of issues that can cause this - if you experience this, start searching the internet.
sometimes it's due to the new sleep mode that was introduced with Intel's skylake chip (around 2021 or so - I think it's skylake). Some people find if they completely prohibit computer from sleeping, that eliminates the problem.
If you can boot the computer into Linux (using Linux on a USB), that's one way to test whether it's a hardware problem. I did that, and worked in Linux, and the computer never shut down. But once I worked in windows, it was initially shutting down several times an hour - with no trace of relevant error in Event Viewer and often, no dmp file was generated.
Prohibiting sleep greatly reduced - but did not eliminate - the random, sudden shutdown problem.
Sometimes excessive heat or overclocking can cause this problem, but that doesn't seem to be the case with the computer I'm dealing with.
It really seems to be caused by Windows 11 having poorly (and incompletely) developed features and possibly incompatibillity with drivers. Many people are experiencing this problem - with a wide range of causes identified, and sometimes, no cause.
Of course, one of the first things to do is to run sfc /scannow and dism (see https://www.windowscent
You can try reinstalling Windows as well. That can create its own problems; back up first, and create a restore point before doing this.
