I have a Dell e7450 i7, the one with the msata port only, not the 2.5 sata port which is the i5 version of E7450. I tried to install a ssd in the WWAN port of that E7450, as I did in a 5580 (in that case both sata and pcie worked 2242 B+M key!). NONE of the ssds I have (sata or pcie b+m key 2242) worked in the WWAN port of the E7450 (Bios and Windows). I wonder if it's something locked in the Bios because nothing is visible in the Bios. The Bios suggests that only another sata ssd would be accepted if it's a ssd connected to a dell docking station ("esata dock port"), zero mention in the bios of a pcie M2 possible option, or another sata port. In that case, maybe in modding the bios those options (m2 pcie or another sata) would become available and would work in the WWAN port. The only thing is those Dell laptops Bioses seem to be almost impossible to mod so deeply (just with SLIC I think). Thank you for your suggestions.

Re: e7450 la-a963p motherboard add bios option
thank you, but this is for the E7450 i5, which has a different motherboard. Mine is the e7450 i7. as I explained, I tried both pcie and sata ssds nvme b+m key 2242, and it failed for both of them in the i7 version. That's why I'm looking for modding the bios.Comment

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice... -
I need someone that can capsulate one of the bios files below, and i prefer the older bios version so i can flash it using CH341A tool into the bios chip.
The manufacturer BIOS files are bigger than the BIOSbackup1.bin files by 256KB and I don't know how to fix or recompile it.
You can see in this link a conversation between me and other people (Starting at page 10) who tried to help me (thanks to their efforts), but i still couldn't fix it and the laptop is considered as dead until now.
Also, I uploaded a backup file for the bios that I extracted by using CH341A...
