The seller sent me other battery.
The same Number battery but else code (Right up corner)
Works perfectly.
I have to and want to recommend this seller with big pleasure.

I did it,
And asked on lenovo forum, where there is problem...

I receive that answer:

OEM battery do have whitelist credentialing in the firmware designed to protect the machine from non certified parts.

It would be best to get the original battery using the Lenovo FRU numbers from parts lookup.

Hi!

Yes, it's correct.

Thanks,

Alpha Centauri is far from Poland :-)
But I have question on theme Update...
1.)  I did points instruction 0 - 2.
2.)  Can I have to before flash I must downgrade bios in laptop to 2.7...? I reads this point correctly?
3.) Points 4-6 are clear.

I have question... how something will make bad?
For example: I assume, I can make only run Laptop from USB. Flash - did not go.

How can I make install - backup bios or bios from Lenovo?

Hi,

I did flash bios version 3.05...?

=> ViQYx

=> 74CN44WW(V3.05)

In Bios laptop I see version 3.7

It is correctly?

I checked my N-2230, I tried change power settings. Any changes and changed bios to version 3.05 (Stock) not give any effects.
Someone try check stabilize connect for 7260HMW??

Hi,

I have question on theme 7260HMW 867M BT4.0 802.11ac Mini PCI-E Wifi Card card.
Now I have Centrino N-2230 and few problems. When I not uses computer, speed card downgrade to 30-35Mb and not returned to 60-65Mb. I have Internet 60Mb.
Speed connect form computer to router is 300Mb - 2.4GHz

Card AC 7260 is stable?
Can someone check own speed connect to Internet for example before and after when You uses the computer. Pause use for example 2 hours.

Now I have Bios 3.08
When I want update to Bios MOD, Have to:
1. Make downsize to version 3.05 (Bios Lenovo) - Ok.
2. But I do not understand point (3) instruction
    I have to downsize version BIOS 3.05 to 2.07...?

Can I ask You about advice?

Followed your instructions but nothing is happening. Also it seems the caps lock light is on and won't turn off by pressing the caps lock key. Is that trying to tell me something?

I'm did it.
In the evening I'll let you know.
Now after reset I have Default - set.

The problem still exists :-( 2019-06-16 10:56 PL

When I connects to router I have 60-65Mb. The connect is stable.
But when I do not uses laptop (for example 2 hours) WiFi speed decreases Max 30-35Mb and not increases when I start uses laptop.
I have to make manualy reconnect with router, and I have again 60-65Mb.
Where is the problem...?

I have driver Intel: 15.18.0.1, Windows 10 x64

The drivers from M$ working the same bad.

How I can resolve problem?
Only update BIOS on 3.5 MOD can resolve it?
