Ok, can you post the dump from the SPI chip that you found? With this package you will likely need a hot air rework station to work with it.
mean,remove my spi chip and post to you?where are you? yes,i have hot air station and i can easy remove it.
yes i can,but i haven't a bios dumper. i have to build it whit an avr or buy programer or... (one week long) why dumping my bios? it is not correct data(bios crashed)!why you need it? no any solution ? when i power bottom laptop 3 beeps heard (1long 2short) but when i plug usb (bios recovery data),no beeps! my usb led flashing 3 second,then usb led stay on. excuse me,i cant writing English very well
BIOS on Laptop consists of two parts - one for Embedded Controller and another for x86 BIOS itself. Manufacturer BIOS upgrade application knows where the upgrade should go in a BIOS and which part goes to which address within a chip. Without manufaturer documentation, which I assume you don't have, it is not possible to know for certain how to cut the downloaded BIOS file to fit it into a BIOS chip. Having the existing contents of a BIOS chip may shed a light on where certain parts of BIOS need to go. As you can see from my post about T530 a few posts ago, the BIOS file that got downloaded from within the laptop OS was not an exact fit for the SPI BIOS chip and needed some cutting. Here is a question for you: Does the cooling fan spin up when your power up your laptop? If it doesn, your Embedded Controller BIOS is likely intact. If not, it may be corrupted.
ok.thanks for answer.if i cant repair laptop whit other way.i try your solution( its last way solution ) yes fan spin up when power up i download my bios from lenovo-support site 6euj42uc.iso and rename it to bios.wph then i make usb recovery whit crisis connect to laptop i hold down Fn+b and power bottom(and Fr+r and Fr+r and winkey+b .........all key) but in all case(or without hold key),usb led 2 second blink and then light on all the time ------------------------------------------------------------------------------------------------- when i remove 2 DDR ram, beep change(1-3-3-1beep)
There's your problem right there. You should not rename .iso files - these are CD images. You should extract your BIOS from CD image prior to trying to flash it using recovery procedure.
i try to extract it,but when open it (whit winrar or...) it is Empty(whit hide/show system file) i burn it to dvd(65 mb space) and again its empty!!! only desktop.ini file with this contain [.ShellClassInfo] LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21815 when i renamed .iso to .wph ,crisis application find all file(need) and show me successful dialog.
