Today I made some tests, the laptop was off and I knew that the battery was close to 20% capacity.
I tried to boot normally as usual, and like before, the laptop has turned off after choosing the normal boot from the boot menu.
I removed the SSD, plug a ventoy USB key, the laptop turned on correctly, it managed to boot correctly on an EndeavourOS Iso. The battery showed 17%.
I’ve reinstalled the SSD and removed the ventoy key, and no boot after the boot menu.
I’ve installed the SSD on the second M2 slot, and no boot after the boot menu.
Then I’ve disconnected the battery, hold down the power button to drain residual power, and tried to boot normally. No boot after the boot menu as usual.
Finally I’ve repluged the ventoy key with the SSD still pluged. And it managed to boot correctly on the endeavourOS iso from ventoy. Which surprised me because last time I did this I had the opposite result. The battery showed 10%
To be honest, at this my guess is that there’s a problem with the SSD. I’ll try to find a new one, and and find a way to clone the actual SSD.
And I think I’ll order also a new battery to increase the capacity.
Hi @Flyred, I have the exact same problem as you. I bought this laptop about six months ago from someone else, and I do not have access to PC Specialist support because I am not the original owner. They will not provide bios/ firmware without proof of purchase.
My laptop is the same model as yours:
TongFang model: PH4TRX1
Version: Standard
Firmware: UEFI
Vendor: American Megatrends LLC
BIOS version: N.1.12A02
Date: 06/03/2021
You need to contact PC Specialist by phone and request the BIOS and EC firmware package. If you are the registered owner of the laptop, they will provide it to you. When I check the drivers using my order number, there is no BIOS or EC firmware available only the standard Windows driver packages. Because I bought the laptop second hand and do not know the original owner, PC Specialist will not send me the EC/BIOS package. Any help or advice would be greatly appreciated. Please let me know if replacing the SSD or the battery has solved this issue for you
I think you should wait and not buy the SSD, as I’ve already swapped it before and it didn’t change the outcome. I suggest trying the battery first to see if that makes a difference.
Hi @zeez, it’s funny you ask, because I’ve just received the battery today, to unfortunately find out the the store sent the 53Wh battery (same as the current one) instead of the 91.24Wh….
Well that’s unfortunate. I guess it will be up to you to decide whether to keep the battery they sent or proceed with what ever arrangement they make with you.
Hi @ricklinux@Flyred I’m 90 precent sure that the battery is the issue the current battery voltage when testing is at 10.56V , the battery is designed to be at minimum voltage 11.61V. I’m going to buy a battery this week . At 50% it goes 11.17V at 35% it’s at 10.8 well below the allowed threshold
Another advice , If you go and check the code on the battery pack it’s PHID1-00-15-3S1P-0 type that in to google, you should get many battery with the same model at cheaper price rather trying to find the battery by writing the laptops model
Hi, no I don’t have any straight answer for the moment. Here below are the last emails. I don’t think I will have my 91.24 Wh battery…..
Hello,
No, I didn't install the battery.
As I've ordered the 91,24WH and receive the 53WH battery instead, I'm waiting for advice to see if we can correct this mistake.
Is there any reason you've sent the 53WH battery ?
Best regards

It’s because it’s designed for 53w only doing more than that could ruin the motherboard. Have you tested the battery that arrived you have got the 53w and did that work ?
I’m pretty sure the website wrote 91.2WH by mistake
The difference between the 2 versions are the the bigger battery capacity, optional nvidia graphics and the laptop is a little bit thicker.
Unfortunately, this means that the 2 laptops chassis are different, hence the batteries are not compatible. We can see on the pictures on this website that the battery is larger and thicker, the screw are not in the same places and larger battery means loosing the second SSD M2 slot on the left.
Anyway, I think @zeez is right, the 91.2Wh capacity announced on the battery provider is a mistake or wrong…
So I’ll plug my new battery and keep you informed if it solves the problem.
I’m guessing the new battery didn’t fix the issue. I bought a replacement, but nothing changed.
The good news is that I found a BIOS/EC firmware update not from PC Specialist, but on the Schenker website. When I searched for the Schenker Vision 14, I found several related laptop models. I can send you the file I used to update the firmware/BIOS. After the update, the boot logo is different. I had to be extremely careful finding the right bios file , it worked in the end
BIOS Version -N.1.15A14
EC Version - 2.24
I’ll let you know in the next couple of days whether this fixes the issue with struggling turning the laptop on .
Sorry, I didn’t give any updates because it was French winter vacation.
I’ve just replaced the battery couple days ago, it was at 60% at the first boot. This morning I’ve used the laptop, and make some power off / power on to check. And the laptop managed to boot at 40%, 35%, 20% and 15%. I’ve powered off the laptop at 5% and it didn’t want to boot again, I mean not even the logo or the boot menu. the battery is having its first charge at the moment.
So right now, it is very promising I would say. I need to do a battery calibration and see on a daily basis if it has solve the problem.
I’m very interested of the BIOS file you found, but sure I’ll wait for your feedback in a couple days.
Unfortunately this morning, the laptop showed me signs of the same behaviour. It didn’t want to boot with 22% battery.
So I guess the problem is not solved….
@zeez If you still have the file, It would be thankful if you could share it with me. Other wise I’ll try to look on schencker website. I guess you have downloaded Firmware_SCHENKER-VISION-14_M21_without-RTX-graphics_BIOS_N.1.15A14_EC_2.24.00.zip. After research it seems M21 is the correct version of my/ours laptop, could you please confirm it ?
