The laptop occasionally stops working or loses power unexpectedly.
HP envy x360 convertible (m6-w103dx) ran smoothly on Windows 10 home 64-bit for roughly two months. Suddenly, while surfing the web, it shut down unexpectedly without any warning or error messages. When I restarted it, the Event Viewer displayed a kernel power event: "The system has rebooted without cleanly shutting down first." Initially dismissed as a one-time issue, the problem recurred randomly, sometimes booting at all times and other times failing entirely. Entering BIOS occasionally would keep it running; other times it wouldn’t.
I checked for Windows and driver updates, found none. Resetting Windows didn’t help. A command prompt scan of the HDD showed everything normal. I also tried a different power cable and even swapped RAM modules—8GB worked on one laptop, 4GB caused issues on another. CMOS batteries were replaced, and I bought a new SSD from Samsung for the HDD, but the problem persisted.
Attempts to replace the motherboard cost around $70 on eBay and only lasted a few hours before restarting again. I’ve been searching for the cause for about six months, unable to spend more than $500 on a replacement. The display, RAM, battery, and random ribbon cables remain intact. I considered swapping RAM, but it crashed during Windows memory diagnostics.
I tested it on another laptop—much worse—and it worked fine for a short time before failing again. Now I’m stuck with a brand-new motherboard after spending about three hours at that cost. No clear solution has emerged so far.
Sometimes just boosting CPU power slightly through BIOS works to resolve the problem. Experiment with small changes. Other factors might involve loose connections, particularly around power delivery—make sure everything is firmly connected. Corrupted system files can also trigger issues; run CMD as Administrator and execute sfc /scannow to check for fixes or errors. Don’t forget to test your SSD as well. Outdated drivers may be responsible for the 41 error. Memory problems could be due to corrupted system files affecting communication, not just the dimmer units. I highly recommend starting with a full Windows update before proceeding further, as this might prevent a never-ending series of issues.
It took roughly three hours for the update to complete. Once installed, there were no available driver updates from Windows, HP support, or Intel. The BIOS didn’t offer any settings for voltage adjustments—just basic options. I managed to boot into safe mode using the command prompt for about five minutes, and the sfc/scannow scan found no issues. However, it crashed right after that and didn’t stay on long enough to resolve anything.
