Hi, this one works sluggishly. Fans ramp up slowly. I've removed BIL, Touchpad, Keyboard and HDD cables. Fans still ramp up slowly and Macbook is slow. I've run ASD without Memory Test cause it takes long and it PASSED all. No serial number being shown in About this Mac. PPBUS_G3H is...

Yes, just tried new BIOS from Ghostlyhaks. No change. Orange light, fans ramp up slowly. No USB activity.

Back to this one. I've tried now USB drive with LED on it. Drive flashes when being used/working. When I use it on this board, it just stays ON. Never flashes, so I guess no USB activity?

Nope, I didn't put tape. First time I hear about it.

No Title I don't have USB with link LED at the moment. But it's on the way. In the meantime, I've soldered BIOS chip using the adapter, but in the programmer, all it says is an unknown device. BIOS pin 1 was where tweezers show.

I plugged the other mouse last time and got mouse activity. This time I plugged a different gaming mouse, no activity. Now I plugged back the old mouse, there IS mouse activity.

I can do that, but I'd like to learn it too, that way it's faster, rather than posting every time and waiting.

Yes, correct values on R644/45. I've replaced them now with new ones. L7630 is 1.05V.

Yes, I flashed new dump from Internet. How do I unlock the old dump?

Back to this board. R7644 and R7645 were looking funky, I've replaced with new. Now I don't have any USB activity.

Connector was actually good. I've touched the pins. Then went over to the trackpad connector. You were right, pins 17 & 19 were bad, but not on motherboard connector, instead of trackpad connector. All eaten up. I've cleaned it, put new solder, tested, works perfect! Case solved! Thank you...

I found R7201 out of its place. U7200 was getting only 2.1V instead of 5V. Put it back, ID0R sensor fixed. As for TS0P, I guess it would be the best to remove connector and check lines? Or maybe I could touch those pins on connector to make them shiny again? Fans are still ramping up slowly to...

If I may ask a small hint/tip/link/direction how to do it? I could just google it I guess, but you guys might have more straight to the point tips.

Unfortunately, all of them are difference: back cover, motherboard (sticker is on the other side) and BIOS. Macbook was EFI locked, I've unlocked it, but haven't cleaned ME region.

Yes, I have the original backup.

Macbook was unlocked with another BIOS, serial number edited. ME region not cleaned. Macbook works so far so good. Starts fast and all that. Do I need to clean ME region? Am I not seeing something I should? Thanks

MBP 13 Early 2011 with different serial numbers in BIOS and motherboard sticker. Would it be possible that someone links me a clean BIOS with a specific serial number? I'd like to match BIOS with a sticker. Thanks

SMC_DCIN_ISENSE is 0.25V. R/C5441 look and measure good.

Voltage pin 9 ISL6259 is 0.25V.

Everything is connected and measures fine. Computer chimes, I can enter OS, just runs slow.
