Pretty strange to see only 1 M.2 slot and only white keyboard backlight. My S7 15ACH6 has 2 M.2 slots and RGB backlight.
Not adding more USB-A ports also looks very strange, since it was the main issue for me.
Overall looks like very bad upgrade for someone already on S7 but with 15.6 screen, despite newer CPU, RAM and NVMe x4 SSD...

Precisely my fear.

By the way, according to the latest market statistics, AMD lost almost 7% of the market over the year (15.7% in the third quarter 2022 instead of 22% a year earlier) in the mobile segment and lost 3.1% in the desktop segment (outside server processors) over the same time - the share fell from 17% to 13.9%.

What I wrote about many times - AMD produces "paper" virtual processors (Intel has also succeeded in this lately, but so far it is taking the market away from AMD) of the "last" generation. But it is simply impossible on the planet to buy the most popular solutions in the same U class with them. Where are all these processors, AMD. Why don't manufacturers release working series laptops 15.6"-16" on 6600U/6800U in mass production? Already Zen4 is on its way, again a virtual series in mass retail until 2024 at best case...

My G5 use huge tuning in OS. It 100% silent in surfing by hours.
In reality, according to reviews, the G5 is 2 times quieter than the L7 series. Naturally, it is slower and consumes less - but it is 4 years old... And there is no more progress, they just increase consumption, and this a priori should not be in laptops - progress when it does not grow or falls (which is even better) and at the same time the performance is higher and higher. Now on the planet the degradation of everything and everything.

Quote from: NikoB on November 12, 2022, 13:56:10I've been enjoying total silence surfing on a Dell G5 5587 in the max performance profile for over 4 years. What do you wish with your new laptops. =)

And in the review of the NB Dell G5 5587 with 1060, it makes only 42dB noise (vs 48+ for new "game" laptops), but it consumes less - but does this do honor to new products with such wild consumption? Where is progress going? In a technological impasse?

The notebookcheck numbers do not agree with you that the G5 is totally silent, but maybe you have yours set up differently or it is special like you.

But the numbers do show the Slim 7 and the Legion 7 (AMD versions), are quieter than your G5 at full cpu load while consuming the same amount of power. And since the G5 chassis additionally gets too hot, this seems like technological progress to me: More processing power, less noise and less heat in the chassis.

I agree it is reasonable to have silence during basic tasks. In fact, I purchased the AMD Legion Slim 7 (for more $) instead of the Intel version so that it would be quieter in use. As you know, amongst Legion laptops, 31db at 100% cpu load is only bested by the Legion 7 (which I did not want to spend extra on).

Quote from: Prisoner Elect Trumputin on November 11, 2022, 03:50:05In CPU load, Legion 7 is 26.8db. Legion S7 is 31.4db. Both 6900HX.

In CPU+GPU load, Legion 7 6850M XT 140w TDP is 54.2db. Legion S7 5800S 90w TDP is 51.2db.

Please apologize to the R&D Dept!

Quote from: NikoB on November 05, 2022, 12:12:01Noise is very good up to average level for cores. But the question immediately arises for Lenovo engineers - how did they manage then, in a larger weight, Legion 7 also with AMD, to make the cooling system much noisier in such a load? Complete absurdity, everything should be the other way around! Lenovo clean up the R&D department!
The numbers have already been corrected since I wrote this. If you follow the new L7, it is almost 2 times quieter in terms of noise in an average load! And this level is already sufficient to comfortably work for a long time for L7, but not L7Slim.

In any case, as a working machine (games do not interest me at all, and all "gaming" laptops with a noise of more than 40dBA cause me only Homeric laughter) L7 is many times cooler than L7Slim both in terms of noise and ports and availability (and this is key, noise by priority) - 2 memory slots up to 64GB in dual-channel mode. Whereas the pathetic L7Slim is limited to 16GB for non-demanding "housewives" in dual channel mode. I do not see any point in buying L7Slim against the backdrop of L7.

Of course! The numbers were originally incorrectly posted by notebookcheck!

Is 31.4db too loud for non gaming load? The Dell G5 which you say you use and is perfect for quiet usage is apparently more noisy than that at idle and far far noisier under load:

"During idle after a cold start and also under low load, silent operation is not possible. While both fans also run during idle, at 31.1 – 34.2 dB(A), the measured volume is not loud. Thus there will always be a quiet whirring. Under load, the fans really rev up, and we measure the maximum value of the Dell G5 15 5587 at 44 dB(A)."

They also said that the case temperature is "simply too high".

See reviews. 26dB(A) vs 31. Every +6dB(A) - it increases the noise by ~2 times by ear.

Please specify what L7 model exactly and what software do you run in average load!

Quote from: Alhena on November 09, 2022, 11:25:37Actually, one more thing too. You said you've used the 99Wh battery. This is literally incorrect - look at the images you've taken for the inside of the laptop. You clearly have the 71Wh variant.
The author simply copied the data from the L7 series and did not edit for the L7 Slim series. But this is another test of attentiveness ... =)

Quote from: Allen on November 08, 2022, 07:27:46We tried two different USB-C chargers, 65 W and 130 W, and neither of them would work. Lenovo sells an optional 135 W USB-C charger which we did not have during testing. We're trying to confirm with Lenovo if the laptop is compatible with third-party USB-C chargers or if users must have the Lenovo-branded 135 W USB-C charger instead.

The 135W charging is proprietary yes. It's not PD3.1 - which is a shame - but rather it's 20V 6.75A. However, I'm confident you should be able to charge at 100W (20V 5A) using the PD3.0 protocol. Maybe 65W is not enough to charge it? I don't know.
