Re: MACBOOK PRO a1278 820-2530 EMC 1413 BIOS
Happy New Year
Thanks for your reply,
From your links and and and from what i have (board) the processor is 2.26MHz core 2 Duo 13".
On SMC ic is written 3089 or 3039 and 340D.
This board i purchased from ebay and unfortunately the seller disappeared therefor i can not contact for more info.
the board when was received supposed to be a working one but it was defective and i fixed it.
I used schematic macbook pro A1278 820-2530 that was more near to board.
So i went thru the RAILS test and all voltages are there. the only difference i have is PPVCOPE_S0_CPU i got 1.08v and on schematic says 1.5v.
That is why i said it is a bios problem.
do you have any suggestions.
There is one IC U9000 pin1 is LVDS_IG_PANEL. there i have .2v and sometimes .5v but there is no short. pins 2&3 have 3.3v.
tracing pin 1 goes to a resistor which is 0v ( measure resistance is ok) and
then goes to graphics ic. Pin 1 should be 3.3v.
can i fet from somewhere!

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

Product Name: Razer Blade 15 (2022)
Product ID: RZ09-0421
Motherboard: CH580
BIOS Versions I work with: 2.02 & 2.06
Bios File Size: 32,768 KB
Dear Forum Readers!
I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).
