Hello,
I need assistance with Legion 5 Pro bios no post/black screen issue.
Lenovo NM-D711 (rev unknown)
SN: PF33Y1Z6
Thank you for your help....Leave a comment:

If someone had the time, I would really appreciate it if you could take a look at my two previously uploaded bios files. I’m not very sure how this works but I would guess that the bios is checked and then repaired if necessary. Any help or direction would be much appreciated. I can reupload them again if that’s less confusing. The first 16mp upload was blank unfortunately. The second is correct.Leave a comment:

I have successfully dumped the 16mb XMC chip backup and it is NOT blank this time lol. This one is labeled 2.0
Sorry for the delay. Turns out selecting the EON EN25Q128 did allow me to read my XMC with AsProgrammer....Leave a comment:

Oh, I’m so sorry! I didn’t even think to verify the dump contents. I will download AsProgrammer and redump.Leave a comment:

On second thought and a google search, I have no idea what that person is taking about. That seems like a ship they are referencing not a software lol. So I'm not sure if I need another reader or another software. I believe my drivers are up to date on my CH341A.
It seems they were suggesting I use the CH341A and manually select the EON EN25Q128 to read the XMC QH128AHIG. I can give this a shot and see if it reads.
I understand now. I removed the heat sink and found a chip nearby the windbond bios chip. My CH341A programmer could not read it but another thread said to...Leave a comment:

Hello Hoaca388,
Just so I understand, I uploaded a rar back up of the 8mb winbond bios chip in my initial post. Is there another 16 mb chip potentially under the heatsink that I need to make a back up of?
I was trying not to dissemble since it is still under warranty. I planned to reflash original bios if these methods failed when warranty restarts. I’m very new to this and was only aware of one chip to flash. Clearly this could be more complicated than I was aware.Leave a comment:

Re: Macbook A1466 dies when charger disconnected
Good idea. I will do that before I install a new battery just to be sure.
Thank you for the heads-up regarding the LCD panel.
And yeah shipping costs are silly lolLeave a comment:

Re: Macbook A1466 dies when charger disconnected
Yeah, I agree.
I just can't afford parts right now, unfortunately. Still don't know why the diode read as it did. I can only assume it is because it was in circuit. But when charging it seemed fine.
Hopefully, when I get the new battery, we will be all set and charging will be normal.
Thanks for all the help!Leave a comment:

Macbook A1466 dies when charger disconnected
Hello all,
Working on my wife's 13' Macbook air. It's been in a box since she upgraded but I figured it could be good practice.
Details:
Macbook 13' A1466
Board (820-3209-A)
Battery OEM 7.3v 50Wh 6700 mAh (020-7379-A)
Pictures below of Boardview and schematic...
I don't know how to test the voltage on a MacBook battery. I just assumed it had an enable pin but the best I could read was 300 something mV poking around the battery connector.
It's an older model and it is very likely that battery has become... -

Re: New Members - please post your introductions here
Hi, my name is Blake and I am learning how to do board-level repair on pretty much any device I can get my hands on. I've come across this forum a couple of times and it has been useful to say the least
I'm looking forward to getting to know some of you. Sorry, this post is not very long.
Two fun facts about me are that I have red hair and that I started getting into repairing things when I dropped my Nintendo Wii about 6 years ago and damaged the disc drive. The silly thing took me three days to fix...Leave a comment:
