Ok mate,
We have to Dismantle the laptop to get your MoBo nacked and find the Eeprom Chip !
Normaly It is located under bottom MoBo and near the ENE Chipset !
Your Eeprom Chip 25 SPI 8 Pins Soic8 is :

--- Flash Devices Found ---
W25Q64BV ID:0xEF4017 Size: 8192KB (65536Kb)

Try to find It then You have to connect the Clip to the SPI PGM and to Eeprom Chip
aligneing all to Pin #1 (on chip You will see a little ball on pin #1) while on PGM
is descripted on instructions !
So after connecting all try to read It and upload here the Full Dump Firmware !
Be aware just only read before all and make backup of Eeprom containing !!!
Let me know
Regards

P.S. I will try to find an Harware Maintenance Manual or Video of It for You !

I'll have a look tonight, I needed to repaste anyway, but I just realised I also need to find a second pc to run the thing's software, so that's going to push things a bit further back. I'll get back to you !

Ok mate,

I'm having an issue reading the chip, the software displays nothing but 00 and FF..

[kimiiee]

Okay, so strangely enough, plugging into the winbond chip gives me an empty read. However, I plugged into a mxic chip that have me a read with stuff inside.

[BDMaster]

Have You removed from MoBo Battery, RAM Modules ? before reading Eeprom Chip ?

[kimiiee]

Aaaand here is the dump ! Ended up not using the clip and temporarily soldering the wires directly to the winbond chip.
