Dell patches 12-year-old driver vulnerability impacting millions of PCs
I read this CVE with some interest, to see if it provides a solution to a frustrating problem, involving a Latitude 5300 (2-in-1). The problem: once the device is fully charged and subsequently shutdown, it rapidly drains the battery to around 80% within a few hours ─ at which point it retains the remaining charge. The problem is less pronounced, when it is put into sleep mode.<p>I have been through numerous suggestions and permutations; &#x27;hard&#x27; shutdown by holding the power button for varying durations, BIOS updates, OS updates (W10 latest build&#x2F;version&#x2F;updates&#x2F;drivers), manufacturer specific driver updates, fresh rebuilds, tweaking power,wake,idle,throttle settings for CPU, network adapters (via BIOS and OS), date&#x2F;time anomalies, turning off Modern&#x2F;Connected-Standby, Registry hacks etc. Furthermore, I have contemplated using Wireshark and other tools to diagnose the problem, but that would require a significant chunk of my time troubleshooting a device, which I expect to work, out of the box. I resent the fact, that no explanation or a solution is forthcoming from Dell, which is a matter of concern.<p>The post below describes my conundrum, fairly accurately.<p><a href="https:&#x2F;&#x2F;www.dell.com&#x2F;community&#x2F;Latitude&#x2F;Latitude-7400-battery-drain-after-shutdown&#x2F;td-p&#x2F;7507300" rel="nofollow">https:&#x2F;&#x2F;www.dell.com&#x2F;community&#x2F;Latitude&#x2F;Latitude-7400-batter...</a>
