Re: Calling P1 and X1 Extreme users to update BIOS 1.19 - fan noise much better now!

Yes power light turns on, cpu fans also turn on and in 2 to 3 seconds the all lights goes off/dead.

 

This happens every time I press the power button. After I keep trying to power on the laptop again and again it may start randomly once.

 

Once it boots it works fine but if it reboot or sleep the laptop it will go dead again.

@DroidCue,

Try to understand - 1 out of 10-20 times, when you press the power button, it doesn't power on? Does power LED light on then dim?

 

Please suggest more details, thank you!

Now it powered on after my continuous efforts of pressing power button (see the attached image) Do you know should I fix this?

Re: Calling P1 and X1 Extreme users to update BIOS 1.19 - fan noise much better now!

@DroidCue,

I'm so sorry for what you have experienced.

I tried BIOS 1.23 on a P1 with similar configuration as yours, and it works fine - including sleep and reboot with AC or battery.

 

Do you mind to re-flash BIOS 1.23? If it doesn't work, I will send the old version to you.

 

Thank you!

 Yes I want to try re-flashing the BIOS 1.23 as you suggested, but it does not allows me to do so.

 

When I try via USB disk it gives me a message : Information: An update is not necessary  at this time. The process has been cancelled.

 

When I try it via Windows I get a message "BIOS image is same as BIOS ROM" An update is not necessary at this time."

 

Question for you: Should there be any command with siwtch to force update or any config change in some file to ingore the version and perform update?

 

(Please check the images attached)

@DroidCue,

Yes, there's a way to forece reflashing the BIOS.

 

Boot to windows, click Win button, type "CMD" , Command Prompt appears on the list, on the right side select  "Run as administrator".

Follow command:

1. CD c:\drivers\flash\n2euj14w\

2. WinFlash64.exe -sd -file ./N2EET41W/$0AN2E00.FL1

 

System will read the BIOS, and then reboot to flash. 

 

Good luck!

Could you please tell me how to rollback 1.23 to 1.19? I have a serious problem about sleeping power consumption and I can't fix it.

Re: Calling P1 and X1 Extreme users to update BIOS 1.19 - fan noise much better now!

@Wdde,

Sorry for not answer in time.Please try to follow the steps,

 

1. download 1.19 BIOS:https://download.lenovo.com/pccbbs/mobiles/n2euj11w.exe

2. Run n2euj11w.exe, by default it will extract the files to c:\drivers\flash\n2euj11w

3. Run CMD as administrator to get a command line window

4. CD c:\drivers\flash\n2euj11w\

5: WinFlash64.exe -sd -file ./N2EUJ11W/$0AN2E00.FL1

 

Let me know weather this works for you.

Re: Calling P1 and X1 Extreme users to update BIOS 1.19 - fan noise much better now!

Thank you for your reply. I tried to rewrite bios with the command line you given, After several automatic resets, there will be an error. I didn't take a picture with it at the time. I 'll  try again later. According to Lenovo, 1.23 cannot be rolled back to the lower version.
