Hi,

Could anyone help me with this pls.?

I have a bad AMI bios flash on my Clevo P650SE(i7-4720HQ, gtx970m 3GB vram, 16GB DDR3L RAM - I've upgraded with 8GB - .. the laptop is from PC Specialist). I was trying to flash this P650SA bios/EC mod over another one and I think now messed up the EC or the bios on my laptop.

Symptoms: Switching on the laptop I can see the boot logo, I can enter the bios only by spamming F2 (there I can see only 1.05.01 for EC and bios version as well)and enter boot menu also only by spamming F7 but it stops and does a thermal shutdown what's coming after 'power on' about 10 seconds all the time.
I did resets in different ways: taking out CMOS battery and disconnecting AC adapter and CMOS battery pressing power on button for 20 seconds.
Tried booting with Fn+B , Fn+D , Fn+S, Fn+win key etc. and still nothing changed, the nasty thermal shutdown are still appears to be.

I'm willing to donate just to get my laptop back to working state.
Thanks

Dear all experts,

Need your advise on updating the bios of a very old laptop.

It is Aftershock S15 (rebrand of Clevo P650SA) and i am thinking of upgrading the bios to accommodate the NVME M.2 that i plan to purchase.

The current bios version 1.03.03, can i update from 1.03.03 directly to 1.05.01 and then go with this modded bios.

Your help is much appreciated. Thanks.

@Ferrous is it possible to continue using my SATA m.2 drive after flashed this version of BIOS currently installed on both the m.2 slot ? as i have not gotten the nvme replacement yet.

Thanks.

Last time this user was online its back to 2017...cant hope too much regarding an answer.
I do give the advice to locate the SPI BIOS chip and do a backup with a programmer.
This is a barebone model as u know, usually customized for/by many sellers and we never really know was was customized besides hw, but most of them r using Clevo base bios.
U should first try to get in touch with seller support to get an updated version of the 1.05.01. EC 1.05.02, if not available from them, u can procede with this flash at ur own risk only.
The bios mod files presented in #1 post r from Hasee Computer.

So u got 3 options here, take the risk and flash this mod, get new updates from ur vendor (Aftershock), flash it and later mod urself the new update or mod urself ur current 1.03.03 bios version.

I am grateful for your prompt respond and great advises.

As far as the update bios version is concern the seller is doing a lousy job. No update since 1.03.03.

I managed to find a clevo unofficial repository that contain all the bios, manual and service manual, from there I downloaded all the bios version since 1.03.03 up to 1.05.01 (B:1.05.01 + EC:1.05.02). Then I update from following the version number, 1.03.03 →1.03.04 →1.03.05 → 1.05.01, so far the laptop is still functioning. Therefore I believed that this is just re-brand of clevo P650SA.

Since I have the bios file of 1.05.01, I will compare it to the modded bios if they are similar except the nvme portion and some minor unlock, I will proceed with the flashing. If the differences are far too much I will take you advise on modding it my self with the 1.05.01 that I am currently running.

One last concern, bios with nvme support will it still work with SATA SSD??? the reason I am asking is because my current setup is with sata ssd on both the m.2 slot.

Thanks.

The mod itself, just adds DXE driver modules to the bios to engage the NVMe PCI protocol and communication, it does not alter any hw structure. And as u can see by urself, ACHI DXE will still load
in the bios firmware. So i do not expect the lost of SATA function at all.
I do advise u to do a clean install of the OS. U can use the procedures sated here by Fernando in his guide [HowTo] Get full NVMe support for all Systems with an AMI UEFI BIOS
Good luck

I will ask at least, to share here that lastest base Clevo bios files u got from repository or share the address with us.

@MeatWar

Thanks for the clarification. I may try to insert with the version i am running now.

unofficial Clevo repository : repo.palkeo.com / clevo-mirror / model number
login : repo/repo

Just search for your model in the repository, should have all the bios files and manuals.

Hope this help.

Hello,
I have the same problem as Tobe1212.

I have a SPI FLASHER and need the software for the ec and bios chip. I used the programmer Ch341a.

Can check the clevo mirror site for the bios files you required.
