I have a VGN-AR41M with password. I disassembly it, but I couldn't find the eeprom. Can somebody tell me where it is?

Follow some photos





Thanks in advance.

I found it. But the vaio analyser cant decrypt dump.

Can some one help me?

The dump:

[h34d_hunt3r]

I full fill the first line with 0x00 and it, doesn't power on.

Any idea? I will disassembly it again restoring it to original.

Maybe it power on again...

Someody sell onetime password in this forum?

I just restored the first line as original... But it don't power on... Is there any security for it?

Hi, \

No reason other than hardware failure, a shortcircuit maybe.
Usually, there are two 24C02 eeproms. I would like to see the original dump, if you can give me a link via email or PM.

And the photos are useless at this resolution, you could post links to the original sized ones.

Hey brother,

With the original file it is powering on. But it doesn't power on if I change some information in E2P.

About the correct IC, I dumped the U31. Follow the Schematics

Thanks in advance,

I answered your PM too.

Well, in this case the eeprom is the correct one. Put zeros at 0x08-0x0f and write the resulted dump and it should be solved.
