Xiaomi Mi Notebook Pro with BIOS 502, can someone please help me?

[Chris G]

I can’t speak for the 502 bios, but my 403 bios do this. The fans are on low with light tasks, but later turn off. Many reports worse fans on the 502 bios means I would hold off if I was you and wait for a newer bios release that is surely coming to fix the fans and SSD speeds.

Hi Chris, thank you so much for the answer. Do you know by chance when a newer version will be released?

I would like, however, to have an honest feedback by some owners of Mi Pro with 502, because I want to know exactly how much is it worse compared to 200

[Chris G]

Okay well, I hope some 502 owners give us some feedback?

Hi, i have the 502 bios and the fans were annoying when gaming older games. I repasted the laptop and had to underclock my cpu ( in windows ) to 80% performance, so it doesnt switch to turbo and now its quiet even when gaming and performance is still enough to play, lets say, mass effect 2 on highest details, temperatures did reach max 58 celsius so far on both cpu and gpu, so im happy with it.

I wish i had older bios, so i could undervolt my cpu. If anyone was able to downgrade bios i would be grateful for help. As i read it can brick your laptop and im worried to attempt it myself. Cheers

Are you kidding me? It’s absolutely normal for a laptop to have fans that make noise while gaming, they have to run fast to cool the heatsinks and obviously cpu+gpu. You have to hear the noise made by fans of my mi pro while I play StarCraft 2 or Heroes of the Storm at ultra details. And this is absolutely normal. But that’s not my point.

I want to know if browsing on internet (while not in charge) on sites like this, Wikipedia, forum etc., fans run at maximum speed (like someone on internet says) or just start and stop randomly staying most of the time quiet (turned off) like mine do.

I have 502 BIOS on my i5.

I read from different sources and can confirm that fans are way more than good. with light using fans don’t turn on even on slow, it just cool or little warm, when gaming or video editing they do turn on gradually depending on temperatures.

On maximum, when gpu and cpu are very hot to touch in games (pubg or smth) they work on 100%, they can be heard, but sound level is very nice, level is the same as regular laptop at average using. And after exiting game it cools down in ~2 minutes and fans go on mid or low speeds, laptop becomes again a bit warm, and few minutes more it is cool as always.

Initially I wanted to downgrade BIOS but didn’t do so because of fan problems, on lower BIOSes many report random fan on low speeds and even not controlling fans speed gradations. So I stick with BIOS 502 + overclock and more than happy with this laptop.

P.S. I overclocked TDP of CPU and overclocked GPU to the numbers as in article, undervolting is locked in bios 502.

P.P.S. more than happy with this laptop, great battery on non-gaming usage with brilliant performance.

Also, thank you Chris for your crisp reviews!

I’m on 402 and the fan is okay… Not the greatest at times it can take a while to turn off. But from your post here it sounds like 502 is great for lower fan use. I’m undervolting so not sure I want to lose that.

I’ve updated last week at 502 and I can confirm that there’s no difference regarding the fans behavior. It’s exactly the same as the 200 that I previosly had. I love this laptop

Hi guys,

I am a happy owner of the Xiaomi notebook pro for the past 5 months but i am a bit frustrated about the low read and write speed of my ssd. I have checked my Bios version with the cmd by typing this:  wmic bios get smbiosbiosversion

And the computer answers me with the following answer:
SMBIOSBIOSVersion
XMAKB5R0P0502

Which i guess means that the current bios version is 502, so why do is still get the slow speeds? 502 is the most current one, or am i wrong about this?

For the ones that are curious about the fan behavior on 502 : its quiet most of the times but sometimes (ones a week)it likes to give the fan’s an nice spin for a few sec while you are wildly web surfing(NOT…Wikipedia). nothing to get irritated with, at least i don’t mind about it.

Please give me an answer on this… i am hopelesssss. i just want to get the most out of my laptop!

I also added a picture of the speeds( i dit the speed test with ”as ssd benchmark 2.0”)

It’s the 16Gb of ram version with te i7 Intel.

Cheers,
