Hey guys! I am pleased to announce that I have found a way to restart the notebook and restore almost all its functionality; In fact, now I can not change the bios without it corrupt again, but at least I have a notebook running again. The repair is simple (following this guide) and requires a basic knowledge of hardware / software computer and familiarity with the soldering to connect the cables (not on the notebook !!) Small introduction: Months ago I decided to change the boot order of my two hard drives in my Asus n56vz with 16gb of ram. After saving the settings, reboot the notebook, however, no signs of life. Already happened once (more than three months before), but I had not realized that it was the fault of this action (it's a shame that it is); at the time I sent in warranty. Label repair to return it said "motherboard replaced." However this time the warranty was expired (a week!) And customer support agreement asus in Naples (Italy) have asked me 300 euro for replacement. On a well-known site of Chinese exports (alibaba), it costs only 150 euro. I left the notebook to the service center a month to see if he could restore the notebook without replacing the motherboard, but they did not succeed (!?). So I picked up the notebook and I did a search on the Internet. I came across this very interesting topic, http://forums.mydigitallife.net/threads/44032-Recover-(or-Mod-)-Asus-NV56VZ-UEFI-BIOS/page3 where however does not explain the complete procedure, as it says that you have to reprogram the bios with an ISP programmer but does not explain how to reprogram the chip, or as lines of code to delete or insert. I'm not a programmer and I would have never succeeded. But it occurs to me that what I need is a copy of the bios running (that I can not take from the site asus because only releases updates, without releasing the full bios, then copy it directly into the chip corrupted rewriting it! That's why I write this post, especially to share these files that are not available anywhere! In fact I had to buy another chip bios functioning from which to copy the bios does not corrupt and complete. I did not know if it would work, but the ISP programmer, the clip to put on the chip and the bios running cost me only 28 Euros (excluding the cost of the soldering iron, tin and solder paste) In any case I could try replacing the chip bios working directly on the motherboard, procedure undoubtedly the most delicate and dangerous. What can I say more? It worked and I'm writing from my notebook Let's start: In the topic provided in the introduction http://forums.mydigitallife.net/threads/44032-Recover-(or-Mod-)-Asus-NV56VZ-UEFI-BIOS/page3 you will find information on what to buy for the procedure, which for convenience pointing you below: -SO8 Test clip -CH341A EEPROM programmer usb (instead of the aforementioned EN25T80, I have not found) -The ISP programmer software and the bios.bin file ( https://drive.google.com/file/d/0BwZfTTfaeIlwY0tIS3V2dEJDM1E/view?usp=sharing) DISASSEMBLE THE NOTEBOOK I helped with this video on youtube. Use latex gloves, remove the battery and benches ram. Disassembly is simple and you have to pay attention to the two wires inside and those of the board wifi / bluetooth. https://www.youtube.com/watch?v=VC_GLPNtn2I For the final step I share this picture that is very convenient to not forget no connector disconnected. In yellow connectors, red screws. Remove the motherboard / cooling system and turn it upside down, so you have to view the bios chip This is the bios we're going to connect later WELD CONNECTIONS I bought a clip without connections, so I used the wire I soldered a series of pin bundled with the programmer, making sure that each pin corresponded to the clip. Then I isolated by passing between a pin and the other tape. DRIVER I put in the system programmer in the USB port in windows 7, the drivers are installed automatically. Otherwise you can translate the instructions in chinese with google translator. Below I provide all the necessary software. In any case, we will need only file CH341A.exe, which is the software programmer. To see if the drivers are properly installed in the bottom right there in the status indicator. In Russian, I found a video that shows how it works https://www.youtube.com/watch?v=zcBp13ofXwU PROGRAM First of all you connect the clip to the chip bios functioning. Must pay attention to the direction of the bios, which has a small dot that indicates the direction. Under the direction of the chip must correctly insert the pins that we welded in the grid programmer. To understand this, next to the grill, there is a small illustration with over written 24xx and 25xx, two rectangles with a crescent and a dot, which indicate the direction of the chip. We are interested in 25xx and collegeremo pins as if we are connecting the chip directly on the grill. We open the program To verify the correct connection of the chip can detect and press the response we should have the completion of the "name" field with "W25Q64BV" In this case we can proceed with the reading of the chip with the "read" and save it with the button "save" Done this now connect the clip on motherboard chip doing even more attention when the clip tends to slip away. We press the button again verification "detect" and if the answer is correct press again "read" and "save" creating a backup with the bios corrupt! Now delete all content by pressing "erase" and verify the operation with "blank" and "read" that will return a series of zeros 000 Now with "open" load the correct bios and press "program" and "verify" Got It !! Disconnect and reassemble the notebook to check to see the proper functioning of the notebook. Before you turn on the notebook reboots once and then on again late "ALWAYS" for a few seconds before the POST screen. Quidni be patient and wait until the POST screen. Again, I was not able to change the default setting of the bios again without corrupting the information in the chip, so I had to redo every time the manual process of rewriting the subject of this guide. Also turning on the notebook is slightly slower for these 5-10 seconds of black screen before the screen post. I hope this guide has been helpful, remember that the file is only for bios N56vz. Sorry for bad english PS: i cant post link or pictures. I wanted to post on this forum my guide, because it is on this forum that I found the most useful information, is there any moderator who helps me?
