The laptop experiences sudden hard crashes without a BSOD.
I own an older laptop, around ten years old, which I've kept in good condition with minimal upgrades. No major hardware modifications have been made recently. Recently, the machine has started to crash abruptly, experiencing a sudden loss of power without any warning. This resembles the behavior seen on desktop computers lacking UPS protection when the power supply is cut off during operation. There are no BSOD errors, crash logs, or dump files produced. I also examined the Event Viewer, but no relevant data was found to explain these random failures.
These incidents occur shortly after the system starts and again after some hours of operation. There was no intensive usage during the crashes—just basic activities like browsing with Chrome. I don't believe overheating is the cause, and no consistent pattern has been noticed so far.
After a crash, I need to press the power button repeatedly to get the laptop back on, and only after disconnecting the charging cable does it start booting again. This suggests a possible power supply issue. Despite being familiar with laptop repairs, identifying the exact problem remains challenging since I don't have a spare charger or battery. Any guidance on diagnosing this would be greatly appreciated.
The laptop might remain powered on after a crash, which could explain why pressing the power button has no effect. In future attempts, try holding the power button for a longer time to initiate shutdown, then press it again to restart. Also consider what you were doing on the laptop when the crash occurred. Are there any power issues in your home? Does relying solely on DC power prevent these crashes? If you think about the laptop's battery, try charging it and observe if it stabilizes. The Windows interface might also show battery status indicators.
My laptop battery is aging yet it still provides about 1.5 hours of backup power. If the laptop remains on after a crash, connecting the charger won’t alter the situation because it would still stay powered via the battery. However, this isn’t happening here. During a crash, the screen turns off, the fan stops abruptly, and several LEDs on the disk or usage indicator blink before shutting down. This strongly suggests a hard crash with no power reaching the system. In my previous post I noted that nothing significant is running on the system at that moment, and I don’t think power fluctuations in my home are a factor.
I’m actually checking whether running solely on battery power prevents crashes, but since the crashes appear unpredictable—sometimes just a few minutes after startup and other times lasting days without an issue—I’d find it very challenging. Using just a 1.5-hour battery would require repeatedly charging it back to full, which could take around 2 to 3 hours each time. That would limit me to at most 2 or 3 periods of about 1.5 hours a day to observe if crashes persist.
But what does "nothing heavy" really mean? Excel, Word, or simply leaving the laptop running without any activity? Every piece of information might be crucial in determining the reason, whether you're trying to solve it yourself or seeking our assistance.
It's mainly a browser, either Chrome or Edge, with just a few tabs active, displaying mostly text. No videos were playing during the crash. Although I occasionally watch videos or do some video processing, I haven't experienced any crashes while doing so.
