8000mAh? No, both have the same battery. But many comments can not interprete what the really battery is, like this: “Yepo 737A Notebook summary of Specs. OS: Windows 10; CPU: Intel Celeron N3450 Core: 1.1GHz up to 2.2GHz; RAM: 6GB; Hard Disk Memory: 64GB; External Memory: TF card up to 128GB; Screen size: 13.3 inch; Screen resolution<wbr />: 1920 x 1080 (Full HD!) Battery Type: 7.4V / 4800mAh; Standby time: …” There are two batteries 3,7V, 4800 mAh wired in series. That means 3,7V, 8600mAh. Same like Ezbook….

At this moment i must disagree, i have found few 737a offers online that has 4800mah in description (probably wrong or ezbook specs copied over and over) however most has 4000mah. And the only pics of 737a battery i was able to find has also 8000mah (4000*2) here: https://junkhack.wordpress.com/2017/12/25/yepo-737a/

But if you find actual pictures of disassembled yepo 737a with 9600mah battery please share here, there might be different versions.

I had both yepo 737A and 3x ezbook 3 pro… Yepo from my expirience has only about 60-70% of the ezbook battery life. Picture of my Yepo 737A inside:

You are right, I was wrong. Sorry. I thought, they use both the 8800mAh battery.

When I opened my Yepo, it looks exactly the same, like the photo above.

I would like to port to other laptops,

can you explain to us which tools did you use to modify the bios?

Hi,
thank you much for your post about flashing the bios of yepo 737a.
I read your post with interest, because i intend to install linux on my yepo notebook. Since now i failed because yepo doesnt start from prepairerd usb-stick with a live version for installing linux (for example linux mint or ubunu), although the bios is able to recognice the stick in the bios settings.
After starting the system the cursor is freezing…

so maybe i have more success with an unlocked bios from jumper.

Now I have a question:

did you use the afuwingui tool to flash the jumper rom direct from windows or what way of flashing did you practice? Because i have tried to open the downloaded jumper rom with the afuwingui and failed to open it with the following error message:

a1-Error: Bios does not support ME Entire Firmware update.

May be you have a solution

Best regards from

Udo

I have successfully modded the original Yepo bios and flashed to my Yepo 737A and now have a fully unlocked bios, so you dont need to use the jumper bios at all, will happily upload it here for others to use.  Big thanks to Giovanni and others for the guide.

Hy Hodin,

thanks a lot for this interesting post.

So, to be sure doingthe right thing for flashing the jumper rom from uefi shell:

I assume that you have prepared  a usb stick with auefi tool an the  jumper rom .

in my unerstanding of the process it is neccessary to mount the usb  in the shell and  then starting the flashing process with the following command:

*auefi jumper.rom /P *

I dont know if its neccessary to set  any other paratmeters (like /B for programming the Boot Block  or others)?

Please  let me know

Thank you

Udo

Hi ajoesmith,

thank you much

Udo

Please see this link for yepo modded rom https://ufile.io/ryczg

Im not responsible if you brick your machine and offer no support, it worked for my machine, use at your own risk!

My bios was YEPO10x.WP313R.NHNAUHL03

Hi ajoesmith,

thanks a lot, your modded rom works quiet good on my  yepo notebook.
Do you have an idea, howto manage it,  booting from a prepared usb-stick with a linux live system.
I know the proper way to prepare the stick but when booting the cursors is freezing and nothing happens …
May be you have an answer

Can someone tell me how to fresh  install windows 10 from USB flash drive on my YEPO 737A notebook?

How to make my USB flash drive first boot priority ?

Thank you in advance

Bonjour Hodin,

(j’ai vu que tu es français, c’est pourquoi j’écris en français) je viens d’avoir un Yepo 737a. Le SSD que je viens d’installer n’est pas du tout reconnu par le Yepo ni par Windows. En lisant ton topic, je pense qu’il faudrait que je flashe le bios en reprenant la rom que tu mets à disposition. Par contre j’ai vu que tu mettais aussi à disposition les différents drivers. Je suppose que ces drivers ont été utiles car tu as réinstallé Windows sur le SSD que tu as inséré dans ton Yepo. Si par contre de mon côté, je ne souhaite que faire reconnaitre mon SSD, je suppose que seul le flashage du bios sera nécessaire (puis paramétrage de celui-ci), n’est-ce pas ? Quand je rebooterais, Windows devrait fonctionner comme avant ?

Merci de ton retour (et merci pour les fichiers que tu mets à dispo)

Oui, tu peux flasher le bios et ensuite normalement cloner ton disque (perso j’utilise MiniTool Partition Wizard Free Edition qui fonctionne très bien). Le bios est super complet et tu as des options pour quasiment tout sauf l’overclocking mais sur SSD, le système est relativement rapide pour ce genre de notebook.

En ce qui concerne ton SSD qui n’est pas reconnu, je ne sais pas si il le sera après le flash. Vérifie déjà si tu l’as bien monté, mais de mémoire, effectivement il faut désactiver une option pour qu’il soit reconnu par la suite (il me semble que ces options sont également disponibles dans le bios original d’ailleurs). Si tu te trompes dans les options et que ton portable ne s’allume plus, reste appuyé sur le bouton power pendant plusieurs secondes pour réinitialiser le bios ou dans le pire des cas, démonte la face arrière pour débrancher le cable de la batterie pendant quelques secondes pour reset le bios…

Cordialement.

You have the command lines written in a text file in my bios folder. You can flash the bios from any mounted partition recognized by the UEFI shell. You normally got listed file system partitions at the beginning of the prompt listed like FS0: FS1: etc… you can list and CD to directories and launch commands from path. I have a text or pdf file in my google drive for UEFI commands, you can start from here…

So you don’t need an external usb drive to flash your bios, you can do it directly from the internal memory drive. Simply prepare a folder at root partition in Windows with simple names to remember (that’s why I also renamed some files to have less complicated typo)  ^^

Hi, as I remember, in order, you must deactivate secure boot in BIOS to properly boot from a live distro. Also, check if you are starting from an USB drive that is correctly partitioned for UEFI boot. I suggest you to boot from an installation partition then make your distro persistent or install it from the key in another bigger partition… You get plenty of tutorials to do this from linux community on the web…

Regards.
