Propriétaire d'un Lenovo Yoga 7 DUET (hybride laptop-tablette), je suis en position quoicoubeh depuis que ce con ne veut plus charger. La seule manière de l'utiliser est de le brancher sur secteur.https://image.noelshack.com/fichiers/2024/33/5/1723813844-full-2-copie.jpg
Lenovo Vantage m'indique 0% de batterie disponible, connecté, absence de chargement. J'ai essayé de mettre le BIOS à jour constatant qu'il ne l'était pas et bien sur impossible puisque la MAJ requiert au moins 30% de charge dans la batterie.https://image.noelshack.com/fichiers/2024/33/5/1723813844-full-2-copie.jpg
Vantage m'indique aussi que ma batterie est dans un état dégradé (capacité de charge total 13Wh contre 41Wh en sortie d'usine), mais limite je m'en fous s'il ne tient que deux heures, ce qui compte c'est de pouvoir l'utiliser ailleurs que branché sur secteurhttps://image.noelshack.com/fichiers/2024/33/5/1723813844-full-2-copie.jpg
Avez vous déjà rencontré ces problèmes (apparement récurrents sur portables lenovo) et comment y pallier ?https://image.noelshack.com/fichiers/2024/33/5/1723813844-full-2-copie.jpg

package.

HOW TO UPDATE BIOS AND EC FIRMWARE BY BIOS FLASH USB MEMORY KEY
1. Make sure that a system main battery is fully charged and AC power is
attached. On tablet system, attach an external keyborad.
2. BIOS Setup item Startup->UEFI/Legacy Boot needs to be "Both" or
"UEFI Only"
3. Attach a BIOS flash USB memory key to the target system.
4. Power on the target system, then press F12 key to show Boot Menu.
5. Select USB HDD in the Boot Menu, then press Enter to make the target system
boot from the USB memory key.
6. BIOS/EC firmware update process will start. Please proceed according to the
display on the screen. System will reboot several times and actual firmware
update process will occur during these system reboot events.
Do not power off the target system during these system reboot events to
complete firmware update process until operating system boots up.
3. Open command prompt with admin rights, cd to extracted folder and run command
mkusbkey.bat [Drive]
[Drive] is the letter assigned to the USB memory key, eg. D:, E:, F, ....
I used 1 GB USB stick.
4. In Linux I created a image file from the USB stick by running
sudo dd if=/dev/sdb of=LenovoUSB.img bs=1M
where sdb is the USB stick.
5. I used USB Monster (https://github.com/digabi/usb-monster/tree/master/src) to simultanously write the image to 20 USB sticks. I have two ten port USB hubs.
sudo ./write_dd.py /home/user/LenovoUSB.img
