![]() ![]() The monitor itself - or any other external device, especially if it's failing - could also be the problem. For instance, a physical connection such as a monitor's cable might be loose, or the graphics card might not be in the right position. Internal components and peripheral devices can also cause black screens. For example, the projection settings might be incorrect or there might be a problem with the boot configuration data (BCD) store. Misconfigured settings can sometimes cause black screen issues. Graphics drivers are particularly suspect when it comes to these errors, although issues such as Windows Explorer not running properly can also be the cause. An outdated or malfunctioning application or driver can lead to black screen errors. This is usually the result of faulty Windows updates, but corrupt or missing system files can also play a role. The operating system itself can be the cause of Windows 11 black screens. When trying to identify what's behind Windows 11 black screens, you should consider the following possibilities: It may take many instances of trial and error to resolve the issue. What's behind Windows 11 black screen?Ī black screen in Windows 11 can sometimes resolve itself before you ever figure out the cause. Black screen errors can occur for many reasons, such as Windows updates, faulty applications, outdated drivers or malware infections.Īs a Windows administrator, you'll have to fix the problem by trying different strategies, one step at a time. It's not because the fixes themselves are particularly complicated but because of the time it can take to try different troubleshooting methods. Hope the information above helps anyone.Black screen issues in Windows 11 can be difficult to resolve. ![]() I have the battery manager running anyways and just didn't found the setting which brought me here. Maybe you can set the values with the power manager and than disable it? The battery control is done by hardware/firmware and no program is required to be running for the settings to take effect. Unfortunately to my knowledge there's no other way under Windows than using the Lenovo Power Manager. ![]() I think it's quite awkward to boot two operating systems one after another just to set this option. I don't know yet what's happening when the system is shut down because my OS ever set the values again during boot. I can confirm that a complete battery rundown resets the values. According to Thinkwiki and my own tests booting Linux, setting the thresholds and rebooting to Windows works while keeping the set values. Because it's an API kept secret and unique to ThinkPads there are no generic implementations neither in other hardware brands nor different software tools (with tp_smapi being the only exception as an reverse-engineered implementation for Linux).įor years I've been using tp_smapi under Linux to set these values. So if you often switch between your desk and walking through your office building you won't keep your battery charging and discharging between 90 and 100%. Not only does it support a stop threshold (so your battery never exceeds e.g. It is actually possible to set charging thresholds on ThinkPads through a proprietary API once introduced by IBM.
