Between this thread and this one I'm seeing mixed reports about this.
For some people the BIOS update worked, for other people they never had the problem, for some nothing works. I was thinking of buying this laptop, but now I'm not so sure...
Maybe with the version of 1050 (no Ti) and an i5 this never happens? Anybody confirms this?
And were anybody able to get a better charger for free from their retailer? And did it solve the problem?

I'll give you my thought on the laptop here, I love the lenovo legion Y530, it's a great laptop,great processing power , great cooling design, and probably the best thing is the design of the laptop. I will consider the power adapter issue as a minor issue, i do say that it is an issue but this doesnt mean that other laptops dont have this issue, in my testing, i ran CPU at 100% usage and GPU at 100% usage, screen at 100% brightness, full cooling boost( which means when the cpu is cooled more, more power is given to the cpu because it can handle the heat, which some laptop couldn't even handle the heat from the CPU and GPU.
So for daily use as a laptop at a desk leaving the power on the laptop, this will not be an issue, most web browsing and games wouldn't even cause the battery to discharge after use , even with heavy usage. Some heavier games like CS:GO might have drops in battery of 3-4% in an hour, which in my opinion is not much i would never run dry with power plugged in, but it just bugs me that lenovo provided a less powerful adapter in the box and i just dont like to see my battery being used when it's plugged in. So you can get this laptop if you like it , this issue will not be so pronounced, unless your work requires you to run you CPU AND GPU at 100% usage at all time, which is not realistic.

W = V * A
135W = 20V * xA
xA = 135W/20V
A = 6.75
But thats the only theory behind current strenght and voltage. SO, in my experience 20V@6.75A is enough for this kind of laptop. But to be honest 135W output is MAX, and brick working on MAX is not good, so it is probably giving 5+A@20v. 170W brick would work fine and provide at best 8.5A@20V, but laptop current/voltage regulator will decide by itself, how much current strenght it needs. Worth a check.

Okay, i have went out to buy a new 170W power brick.
I ran the same test but on the 170W power brick , 100% CPU 100% GPU 100% brightness , cooling boost turned on. but this time there was no battery drain.
here are the results.
20 minutes into the test
i guess i have to say that 170W power adapter is the sufficient power that the lenovo legion Y530 need ,the 1% power drop dont really bug me because i think the battery wont charge before it drops to 95% power. but there is a significant different as compared to the results for the 135W power adapter. I guess these are the places that company are cutting cost on. until youtube reviewer starts do a test for power adapter , company will just find ways to cut cost under the radar. but it's not a big issue , but a sad thing to find out from Lenovo.
So i guess that concludes this thread, a 170W power adapter does work on the legion Y530 and it can draw 170W for the CPU and GPU. you do not need to get one if this doesn't really bugs you. but just good to know that you can get one for upgrade if you want to later on.
And notes for youtube reviews: maybe you can add this test to see if company are cutting cost on stock power brick included in the box.

Well I guess in a way indeed getting a 170W is a solution... But it really shouldn't be, because it should be supplied with the laptop. Thank you for the testing and the information.

Yesterday I stress tested my laptop at 100% load with prime 95 and with furmark battery dropped still a lot with the 170w power supply. Now draining battery a lot and see if it shuts down when battery almost depleted or not..... Battery status says condition good. Might be a faulty battery.....
What spec of laptop do you have? im having the i7-8750h and GTX 1050.

Can you tell me where you bought this charger from? I think i read somewhere someone was able to get it free from lenovo after chatting with them. Unfortunately there's no chat here and Ill try the retailer number they mentioned. Until till if you can drop a link if you bought it online or whereever you bought it from.
