Подскажите где скачать пакет драйверов и фирменных утилит? Сущетсвуют ли они в принципе для десятки.
10-ка выклядит неплохо и работает шустро + автономность по сравнению с 7-кой получше, но не все комбинации кнопок работают. А также отключение микрофона, беспроводных сетей. Еще настророжил пару раз неестественный свист винчестера. Пришлось вернуться на 7-ку)
Или лучше 8.1 ?

Драйверов под Win 10 для этого ноута нет и не будет.
Ноут отсуствует в списке аппаратов Lenovo, которые проверялись на совместимость с Windows 10.
https://support.lenovo.com/ru/ru/solutions/ht501286
Для того что бы заработали Fn надо установить драйвера и утилиты от других ноутбуков Lenovo
Power Manager Driver
https://download.lenovo.com/pccbbs/mobiles/n1mku52w.exe
Hotkey Features
https://download.lenovo.com/pccbbs/mobiles/n1avu35e.exe
Насчёт шустрости Win 10 вы наверное сравнивали свежеустановленный Win 10 и Win 7, который проработал несколько лет и накопил «хвосты»
Насчёт Win 8.1, дело хозяйcкое, лично до сих остаюсь на Win 7

спасибо Вам и Давиду Марковичу)
Была свежеустановленная 7-ка, потом установил 10-ку.
Из впечатлений — увеличилось время работы от батареи, 10-ка загружается быстрее. Визуально она тоже лаконичней. Но, 7-ка уже изучена вдоль и поперек, без лишних постоянных обновлений + работают все Hot Keys. Больше всего напряг звук работы винчестера (редко, но все же). Поэтому вернул 7)
Думал, может просто не нашел корректные драйвера) Жаль, т.к. ноут на общем фоне бюджетных довольно надежный, не смотря на возраст. Возможно попробую по вашей рекомендации установить драйвера от других моделей, а если нет, то придется, проапгрейдить ноут установкой SSD)

на форумах много жалоб, что после очередного обновления Win 10, перестаёт работать то одно, то другое.
Пока Win 10 система очень сырая.
Добавлено 11 минут спустя:
Даже установив драйвера вы не сможете включать/выключать сети WI-FI.
Я знаю, как это сделать, но «это совсем другая история»
Если надо, то могу написать позже — сейчас пора спать

Буду признателен — возможно пригодится)
А с 8.1 ситуация как и с 10-кой? Или более корректно работает на Т420 ?

это одна и та же система. Интерфейс пользователя разный (вернее разный для смартфонов и компов у 10ки). Плюс в десятке поотрубали простые возможности пользователя по администрированию (бояться что идиоты нажимают кнопки как попало, блокируют). Но если Вы в состоянии понимать что и как Вам надо, то ни та ни другая система для Вас не будет ограничением и разницы особо не увидите.
Для того что бы утрамбовать 10ку на Ваш ноут нужно попотеть. Вопрос: оно Вам надо?
Насчет винчестера. Думаю про звук Вы ошиблись. Не может звук меняться от системы к системе. Не перепутали с вентилятором??? Вот он мог крутиться сильнее.

Практически такая же ситуация — нельзя например управлять уровнем заряда аккумулятора(Lenovo Power Manager работает только в Win 7)
для включения/выключения WI-FI скачайте https://yadi.sk/d/HFum5DnJ3BmXPo
разархивируйте и запустите TpFnF5.exe
Предварительно д.б. установлены Power Manager Driver и Hotkey Features

Всем спасибо за советы. Получается, что 10-ка станет нормально как на обычный компьютер, все будет работать за исключением комбинаций Fn и фирменных утилит (насколько они нужны?). Но в силу корявости системы она может начинать сбоить (как и на любом другом компьютере).
Значит, самый надежный вариант оставить 7-ку и поставить SSD)

Updated April 3 2021##
This is list of Windows 10 (64bit) T420 drivers that might be useful to someone else and to make sure I have the latest version of «all the things,» and whether I missed anything. All tested on my personal T420-4180CM6 (except SmartCard and Fingerprint Reader, which I don’t have). It should make most of the FN keys work, among other things.
Not all drivers are absolutely necessary, a lot of things work okay with the genericAF Windows drivers, I just made this list to be thorough. Some of the Windows 7 drivers are actually newer than the generic Windows ones…
IMPORTANT NOTES NOV 2019
I’m currently working on updating this list, Lenovo in their infinite wisdom keeps mucking with Vantage, which wreaks havoc with the house of cards that is the combination of Lenovo PM, Lenovo Power Management, and the Lenovo Interface Foundation.
A lot of this just installing the new driver doesn’t work, you have to manually update via Device Manager, a number of system devices will find updates from M$ if done manually — I added a list of the devices this works for below.
Mini-rant about «Driver Updater» Software
I’ve tried a lot of them, they’ll try to get you to pay money to install drivers from dubious sources that won’t work for your system anyways. For example, the 12.x.x.x version of Bluetooth drivers are for BT4.0 and make 3.0 devices not work.
If they told you the truth about your system being up to date and didn’t find anything, they wouldn’t be able to scam you into buying a copy.
Windows 10 1903
I did have to «force» the update using the Windows Update Tool as it was giving me the «Your Device Isn’t Ready.» So far, everything seems to work just fine with a few exceptions:
-
The Camera App didn’t work even with the default drivers. I forced the Realtek drivers AGAIN and it works. (see below for more information)
2) A «MAP SMS/MMS» in Device Manager with a question mark when a cellphone is Bluetooth linked. Under «Devices and Printers» in Control Panel find your mobile device -> right-click -> properties -> services tab. Uncheck MAP SMS/MMS.
Windows 10 1909
No notable issues thus far. At least not driver-related ones.
Windows 10 20H2 UPDATE IMPORTANT
DO NOT install any Conexant drivers, just use the windows default.

I had to do a clean install of windows 1909 with no drivers installed and let it update from that. The various epic things I tried to do to get rid of the conexant drivers didn’t work, and 20H2 went into a bluescreen loop.

Quirky
It took some wrestling with Windows to make it keep these and not auto-install ones that didn’t work — namely trying to install Ricoh drivers when it’s not a Ricoh device. If your camera isn’t working after installation, check to make sure the driver version matches the correct manufacturer (ie, not Ricoh) in Device Manager.
It didn’t seem to matter which device I picked when manually installing the driver, as long as I picked one of the Realtek ones.
Under Device Manager -> Details -> Hardware ID’s VID_04F2 is Chicony, which uses a Realtek Chip.
Integrated Camera Driver 10.0.18362.20112
https://support.lenovo.com/us/en/downloads/ds502998
Brief instructions for «Forcing» the driver:
Update Driver
Browse my computer for driver software
Let me pick from a list of available drivers
Have Disk
Copy manufacturer’s files from C:DRIVERSCAMERAN29CA04W (default location)
Realtek -> Integrated Camera (may have to experiment with which Realtek to pick)
Update driver warning [Yes]
Additional note — the W10 Camera App is . . . quirky (to put it nicely) about detecting the camera. The camera may still work in other apps. I personally found an OEM version of Cyberlink’s YouCam 6 that (A) works more consistently and (B) offers more functionality than the W10 App.
For some users, the Rico SD card thing causes 100% cpu usage, either disable/enable in Device Manager as needed or just get an external card reader.

Thermal Controls
In my experience the T420 runs hot, TPFC is needed to make the fan run full speed (~6000rpm)
I use Throttlestop set up to still allow throttling for safety, but only down to 2GHz instead of 800MHz

Available via Manual Update
The chipset drivers above seem to work fine, if you like you can manually update the following. (Go to Device Manager and use the ‘Search Automatically’ option. For some reason Intel now dates their chipset drivers to 1968 so they won’t over-ride existing drivers — this is the work-around.
