Thanks for the information. I'll see what I can do.... -
Yeah there are connection between the ec and the main bios through spi rails, now i just checked a random bios from a legion uploaded here on badcaps and a ec dump (posted here too) using HxD and the main bios contains the ec programming, what I don't know about is that you said it needs a bootloader, I was planning on buying just a "new" ec. I guess it should be blank I usually buy from that store on China and they send me good ics....Leave a comment:

Lenovo Legion 5 EC question
Hello guys, do you know if this EC IT8227E-256 need programming? I checked another post where some guys said that the IT8227E-256 can program itself from the bios using a blank ec, but i'm not sure, does anybody know for sure? I don't have an ec programmer so I want to know if I need to buy it programmed or I can buy it blank, it takes a month to arrive to my country from China, so don't want to wait that much twice.
EC had a little explosion and got the 3v LDO shorted btw.
Thanks

I guess from asus site [url]https://rog.asus.com/desktops/mid-tower/rog-strix-ga15-series/helpdesk_bios/[/url]
Btw that uefitool thing that I said is for intel motherboards, I didn't see that yours is an amd, so my bad, I haven't programmed one of these, but I guess you can just download it and program it, in any case save a backup from the original, and do it twice, with different softwares, asprogrammer and neoprogrammer for example (I use these with the ch341).https://I guess from asus site [url]...br /> Btw that...Leave a comment:

Nice, I got a lenovo legion 5 with a blown up EC it8227e-256 and I will get a blank one, I hope it will program itself (I don't have a programmer)....Leave a comment:

Alright, try to check a video about programming one of those bios, the few times I've done that on asus desktop motherboard I had to use uefitool to extract the bios body (something like that) before flashing the ic.Leave a comment:

I see, well the only thing you have left to do is to check around where you took a screw or disconnected something and try to check if there's a smd component missing, also you could try to turn your computer on while disconnecting fans for example, sometimes we bend stuff while plugging connectors... and try only one ram slot (this is not very likely but still)....Leave a comment:

It looks like a bios issue, have you tried to reprogram or read your bios ic?Leave a comment:

For 10 seconds you get all theese voltages? Have you checked 1.2vddq and 2.5v power supplies? those can be killing your power on sequence, check carefully, maybe a power good resistor has been knocked out or even the bios is not properly flashed, if other guys have messed up with the laptop you might aswell check if the bios has soldering traces....Leave a comment:

Check REGN, the 6v ldo on the charger, if this is not present you have a faulty BQ, also check if it gets hot, this ic should be quite cold....Leave a comment:

I see thanks mate, i'll check that store next time i have to buy something, i usually buy random stuff from shenzhen hong ming (they don't offer programming tho), so far their ics work fine....Leave a comment:

ITE EC programming outside
Hello, so i got this asus fx516 for quite cheap, one of the numerous failures on it is the EC (3v ldo shorted), a bga ITE IT5125VG, so i went to aliexpress to the store i usually buy mosfets and other ics from and asked if they could sell me this ec programmed, and they say YES SURE, so i bought it, i sadly don't own an svod yet (I do this as a hobbie). And i was wondering, it's possible to program an ec outside the laptop? I've seen this done on a laptop through the keyboard connector and even the battery connector, but not outside, at least not on bga ec (IT5125VG). Has someone done this before?... -
Here, got it from their official website...Leave a comment:

I just downloaded it from their official site and re uploaded it to google drive.

Have you tried to download another bios from dell? I found a bios for that device on indiafix too, you could try to download and program that.Leave a comment:

Took out the pch and the short on 3v is gone, but the one on vcc_core on the cpu remains, so cpu and pch are gone (this is the weird thing), also took out the shorted mosfet that way I have no shorts on the motherboard anymore, in theory if I replace both, cpu and pch this should work again, but it's a high risk and expensive play, I guess I will just save it in case I find another motherboard 😅

Indeed my friend, the cpu got shorted sadly, it has 0 ohm to ground on vcc_core (this cpu should have like 50 ohm), I found solder traces on the main current sensor, so probably when the third mosfet on the middle got shorted (I know this is the one) this guy injected 20v in there. Which I kinda understand, but honestly I have no idea how the 3v rail got shorted (3v power supply is fine), and i found like 20 capacitors and a few more inductors and current sensors taken aside (like the capacitors on the picture) on that line, I guess he was trying to find a "shorted cap"... I bought this...Leave a comment:

Are these mosfets the right ones?
Hello, I got this motherboard HP G3M dag3mmb2ca0 for repair and I found out that it was a mess, short on cpu's vcc_core and 3vs5 (shorted pch) and a lot of moved capacitors, apparently one of the cpu's dual mosfet got shorted and someone injected 20v directly to it and I don't know if these mosfets are the ones that belong on this motherboard QA3111, I had another victus with i5 (this has i7) and it has different ones (NTMFD1D6N03P8-D).
Someone who have worked on this motherboard maybe know if these are the right ones? I guess they are, but better be sure, besides they seem moved and not...
