Hi! I’m posting this trying to help my brother with his laptop. He has a Lenovo V110 (full model number V110-15IKB) with an Intel i5. He is not really satisfied with the speed of his computer - and it’s an i5 that he is trying to game on, run virtual machines and do other kinds of resource-heavy stuff. That is understandable if you consider the hardware he has.
But, there is something fishy that both he and I are confused about. When the computer boots up, it sometimes prints “Under-voltage detected”, then crashes and reboots saying “Power loss detected”. Apparently he did a BIOS upgrade and it’s now improved, but it still occurs every now and then.
I am not a hardware expert - I am a programmer. But I installed CPU-Z. The only thing I’ve only messed with clock speeds on is a Raspberry Pi, but I hope I can get some help from experts here. CPU-Z on my Acer with an i7 (so I had something to compare with) showed a core input voltage above 1 volt. But on my brothers computer, this value is 1. not stable at all. It jumps from 1.1 to 0.6 to 0.9 and this changes every second. 2.The lowest value we measured was 0.589V. Google told me that an i5 should have at least above 1 volt. Remember that we don’t want to undervolt this CPU, we want it to work normally. It’s an i5, but my brother claims that when some of his games crashed, the Watchdog timer said that it was because of undervoltage. I haven’t been able to confirm that though. Roblox runs at 10FPS, so the undervolting might have something to do with the decrease of performance in his programs.
This computer is a Lenovo laptop and not the most expensive one. I have helped my brother with it quite a lot - OS reinstalls, blue screens and so on, but it’s finally working again except for this voltage problem. The laptop is about 2 years old and already has some other hardware defects. Lenovo is not the best brand and the warranty is expired. But what is the best solution? I assume the answer is a battery replacement or replacement of some other hardware (it makes no difference if the power supply is plugged in or not, and we also have two supplies that we have tested with).
I would really appreciate an answer or steps for troubleshooting and can provide more information if you need to, including screenshots of course.
The computer clock settings has never been messed with, it’s all default. It has never been overclocked or anything similar.
