Schematic for Samsung NF310
Hello to everyone. Just want to ask if you guys have schematic diagram for this old unit. Samsung NF310. Board model: Shark-10 Rev. (1.1) ba41-01363a. This is the only model printed on the board.
Issue: Does not turn on when i press the power button. 19v is present on the board. No voltage on power button. Voltage present on battery charging pins. No 5v/3v, at least to my knowledge. Thank you. -
Re: Asus X415 bios file needed
Good day to all, sorry i was not able to get back soon coz i got sick.
Anyway, I would like to thank everyone for the help. And also many thanks to SMDFlea for sharing me the file. I can confirm that his bios did the job and I'm now able to detect the nvme drive. So far everything is working fine. Cheers to us!

Re: Asus X415 bios file needed
Hi, there is no qr code under the wifi card. As for the whole board, this is the only one i found though it doesnt point me to any website. There are qr codes on other components such as speaker, battery pack and the casing itself....Leave a comment:

Re: Asus X415 bios file needed
Just an update. The file given by hoaca388 from comment number 6 worked. Although the nvme drive is not being detected. Some say bios could still be the issue. I have very little knowledge of these newer systems unlike the older systems. I guess i am outdatedLeave a comment:

Re: Asus X415 bios file needed
@Repdata Unfortunately its not working. The system does not power on with that bin. But thanks.
However bios file i recently uploaded turns on the laptop but there is no display. The fans seems to throttle when cpu heats up. Hope someone has fix for bios or any dump file same as the board code mentioned. Thanks....Leave a comment:

Asus X415EA bios file needed
Hi everyone. I've got a laptop that was brought to me with water damage. Board is beyond repair coz of the burnt marks that penetrated the pcb.
The owner bought a replacement motherboard online but he did not notice that there is no bios chip on it. I try to salvage bios chip from the damaged board but two of my programmers were unable to read and extract data from it.
I ordered chip and will arrive tomorrow. Does anyone have a bios dump on this one? Motherboard code is X415EA R2.0, laptop model is Asus X415 core i3 version. chip model is gd25b127d. Hope someone... -
Re: Acer e5-576g no cpu voltage
I see. well most likely there's a short either with the gfx or ram supply area that has conflict between cpu vcore. I don't know if injecting voltage will help since short happens after powering up. Finding the component that's heating up may be difficult because as of now, my best bet is using thermal camera which i do not have. Maybe i will try to remove gfx coil and ram coils too.Leave a comment:

Re: Acer e5-576g no cpu voltage
Good day my friend. Ram voltage is 1.35v with or without ram installed. And yes I tried different working ram.
One thing I also noticed is that +1.35v gfx voltage on PL2 is also 0v when ram is not installed. (page39) I has 1.35v when ram is installed.Leave a comment:

Acer e5-576g no cpu voltage
Good day.
I've got an Acer E5-576G with no cpu voltage present when unit is turned on. Blue led light indicator is turned on and cpu fan spins. This happens when memory module is present in slot.
Scenario A
-When I turn on laptop WITH memory module inserted, cpu vcore shows 0v on PL3, PL4 and PL5 (page36) And voltage is present on vgpu core on PL7 and PL8 (page38) At this state, laptop turns on with no display.
Scenario B
-When I turn on laptop WITHOUT memory module. cpu vcore is now present on PL3, PL4 and PL5. But vgpu core on... -
Re: Asus GL503V does not power on battery
@myth77
Laptop turns off immediately after removing charger with battery connected.
At B+ I get random voltage between 5v to 8v. Its like ticking with 1 second interval. This happens without battery. If battery is attached I get 0v on B+
PR505 and PR506 resistance is ok (220k ohm)
I got 3.3v on CLK and DATA on PCN2 connector.
I get 100% battery in Bios pls check image. Thanks...Leave a comment:

The battery is good, so I ruled it out from the start.Leave a comment:

Re: Asus GL503V does not power on battery
I still haven't found any solution to this. I replaced charging IC BQ24780s 3 times. I also replaced PQ82. All surrounding components on PU15 was also checked and found nothing faulty. I even replaced PQ26 and PQ27 just to make sure, but still battery wont charge and voltage on P_MBAT pins 1,2 and 3 is fluctuating. What else could I possibly miss??? I'm beginning to realize that I may not found a fix for this... Hope someone takes a glimpse. Thanks.
PS laptop works perfectly fine, I just cant charge the battery.Leave a comment:

Re: Need working bios for Dell 5520
djems3, with your bios i get 7 beeps which points out to processor. most likely this bios is from different processor. Mine is an i5-3210m (SR0MZ) with Amd 216-0833000 Mobility Radeon HD 7670M gpu. Anyway thanks for sharing.Last edited by lezsimply; 02-26-2021, 10:50 PM.Leave a comment:
