Re: LENOVO G50-70 Bios Password
Thank you very much. I'll try to find how and where is the DMI area. If someone else can help, that will be fantastic !
Thank again ...

LENOVO G50-70 Bios Password
Hello,
i hope i'll be ok and not against rules with my request.
So i have a Lenovo G50-70 , S/N : YB08544882, MB model : ACLU1/ACLU2 Rev 1.0 with Bios Password locked.
I try with autopatcher and the result is : "Dump.bin is corrupted or does not contain a valid dump".
I think my model isn't compatible and some skills missing me to remove the password by myself.
Can someone help me to do that please?
Thank you very much....

Re: [REQUEST] Asus battery connector : Pads issue
The card works well on the mains, the PC shows no other signs but perhaps the problem comes from the load management chipset?
He changed the battery with an original manufacturer because the previous one no longer worked.
Why have a blue wire on the battery and not a blank like on the other side if there is no connection?
Do you know what this thread represents by any chance? It's just for my personal culture
Thanks again.

Re: [REQUEST] Asus battery connector : Pads issue
Ah yes, I feel stupid for one out of the two... Indeed, the first from the left is not connected, on the other hand, the one on the right is on a blue wire on the battery side.
I tried before desoldering everything to connect the battery without these pads and it does not work.
I wonder if it's not connected to this track but I wouldn't want to do that randomly.
Thank you for the answer ...Last edited by kurtspirit; 09-08-2023, 10:48 AM.

[REQUEST] Asus S413DA battery connector : Pads issue
Good morning,
I have a friend who dropped off his Asus just now. He tried to change the battery but tore off the connector.
I can catch up on both tracks but I'm missing two pads that don't have visible tracks to bridge.
Can you help me please ?
Thanks in advance.
The laptop is a S413DA , i don't find any boardview....

Re: TUF505DT : No charge
To be honest, I don't know.
I think a Mosfet (I changed them all) caused this broken line but that's really a guess...
The previous battery had suddenly stopped charging for no reason, that's when something happened but it will remain a mystery.
I changed in the end: battery, the 3 Mosfets, the charging IC, a diode.
Thank you very much to everyone anyway, it's a pure pleasure to see the PC working again!

Re: TUF505DT : No charge
How to thank you?!
The PC is finally charging! I'm so grateful, I never thought I'd get there. It's awesome ! I'm really happy and thank you ten thousand times

Re: TUF505DT : No charge
Ok mon2, now the resistance is about 0.01ohm. Maybe i have to test with battery ?

Re: TUF505DT : No charge
The trace is clearly cut. I'll put a wire instead.
For the pics, i'm sorry but when i use the link from forum , pictures doesn't appear in the message...

Re: TUF505DT : No charge
The problem is that the two traces side by side are in contact... I'm not sure that's normal

Re: TUF505DT : No charge
Hello,
Here is a picture from the zone. The two red marks are points where i find the measurement. If i follow the datasheet, ACN and ACP are 1 and 2 on the BQ.

And here is a picture from the zone. To be honest, i don't find the resistor. I don't find a boardview file for this board... Thank you really much for your help
[url]https://ibb.co/Rc9DHhv[/url]
And i just find something on the other side of the board : I found a completely cut track on the other...Last edited by kurtspirit; 03-31-2023, 12:33 AM.

I still stuck with this charging issue :/ Is someone have a boardview for this laptop please?
I don't understand what happen with this case. Thank you very much.
