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,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice... -
Hello,
I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).
But today it's not accepting my password. I'm %100 sure i'm entering the correct password.
I'm trying to reset my bios without success.
I tried :
-I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries... -
With ASUS, not everything is quite so simple. I will show you my way. It may be longer or harder but it is the right way to do it in my humble opinion.
For example, you can have 3 similar ASUS motherboards, all being the same model, all of which will have different BIOS versions.
I will give you an example and my version of preparing BIOS from ASUS website and in the process I am always cleaning Intel ME while doing it so you have fully cleaned BIOS, no DMI data, no password, nothing.
This is the picture of 3 similar ASUS motherboards, all of them being X555LD...
