Sony laptop: Battery not recognized post Windows 11 clean install from USB
Hello there, friends. The setup I had was an old Sony Vaio PCG-71614m laptop (about twelve years back) gifted by a friend. He mentioned it held a lot of personal and professional information, so I asked him to clear all folders and delete everything. There were also several Windows login accounts visible. Doing this manually would have been a long process and messy, so I opted for a quick fix. I used the W11 Media Creation Tool on a USB drive, wiped the whole storage, and installed a brand-new version of Windows 11. Now it runs smoothly except that it no longer recognizes the battery. To be sure, before wiping, I was still using it on battery power for many hours. I think I might have erased some important Vaio partitions—some were visible. I’ve looked up solutions online extensively, tried commands in CMD and PowerShell, and checked for Sony-specific software. The links I found seemed unreliable. One source even offered a proprietary download tool, which I deleted right away. Since the Vaio brand is no longer available, finding the right software is tough. There’s a button called ASSIST on the laptop; I’m convinced it was linked to the disk partition, so clearing it might have helped. The battery is easy to remove—it just pops out and slides off. When I tap the battery icon in the system tray, it says it isn’t detected, and the icon shows a cross. Device Manager lists the system as: Windows 10 Home 64-bit (version 19045). Everything seems fine except for the battery status. I’ve tried everything I could think of. Right now, keeping the laptop plugged in defeats its intended use. I wish I had left the partitions untouched during the W11 installation, but it’s too late now. A valuable lesson learned. Thanks!
I own an older Vaio with a Windows 7 setup. Back then, drivers were necessary for basic operations. After switching to Windows 10, I likely had to remove those drivers, which affected function key support. I expected it to work off battery power since missing only the reporting capability. Considering its age, an original battery might have degraded significantly. It tends to drain quickly, and without testing, I suspect it wouldn’t last long without a power source.
Thanks everyone for your help. I'm still looking for the shared library, control center, and power management software. It seems Sony has removed all traces of Vaio from the web. Finding the .ISO files from recovery disks helped a bit, but they didn't work. I'll keep searching tomorrow or so. If I can't locate anything, I'll give up and accept that this system is now permanently connected to the power source.

Thanks for sharing the links. I already had those downloads except for The Vaio Care, which worked fine—appreciate it! I realized that when installing the other files, they show up as a duplicate of Windows and don’t display battery information at all. It seems my original factory setup damaged a Vaio-specific partition handling these features. I’ve been trying this for a while without success. For fun, I’m planning to boot from a Linux Mint LiveUSB to check if the battery status appears. Thanks again for all the support. After testing Mint, I’ll decide to treat the laptop as a mini PC and place it on a small table. It connects via HDMI to a Sony Bravia TV with wireless KBM, so even though it’s not portable, it functions perfectly.
