In this situation, external hardware (see hardware requirements above) is needed which can flash the SPI chip (where libreboot resides). - </p> - - <p> - Remove those screws and remove the HDD:<br/> - <img src="t60_dev/0001.JPG" alt="" /> <img src="t60_dev/0002.JPG" alt="" /> - </p> - - <p> - Lift off the palm rest:<br/> - <img src="t60_dev/0003.JPG" alt="" /> - </p> - - <p> - Lift up the keyboard, pull it back a bit, flip it over like that and then disconnect it from the board:<br/> - <img src="t60_dev/0004.JPG" alt="" /> <img src="t60_dev/0005.JPG" alt="" /> <img src="t60_dev/0006.JPG" alt="" /> - </p> - - <p> - Gently wedge both sides loose:<br/> - <img src="t60_dev/0007.JPG" alt="" /> <img src="t60_dev/0008.JPG" alt="" /> - </p> - - <p> - Remove that cable from the position:<br/> - <img src="t60_dev/0009.JPG" alt="" /> <img src="t60_dev/0010.JPG" alt="" /> - </p> - - <p> - Now remove that bezel. Remove wifi, nvram battery and speaker connector (also remove 56k modem, on the left of wifi):<br/> - <img src="t60_dev/0011.JPG" alt="" /> - </p> - - <p> - Remove those screws:<br/> - <img src="t60_dev/0012.JPG" alt="" /> - </p> - - <p> - Disconnect the power jack:<br/> - <img src="t60_dev/0013.JPG" alt="" /> - </p> - - <p> - Remove nvram battery:<br/> - <img src="t60_dev/0014.JPG" alt="" /> - </p> - - <p> - Disconnect cable (for 56k modem) and disconnect the other cable:<br/> - <img src="t60_dev/0015.JPG" alt="" /> <img src="t60_dev/0016.JPG" alt="" /> - </p> - - <p> - Disconnect speaker cable:<br/> - <img src="t60_dev/0017.JPG" alt="" /> - </p> - - <p> - Disconnect the other end of the 56k modem cable:<br/> - <img src="t60_dev/0018.JPG" alt="" /> - </p> - - <p> - Make sure you removed it:<br/> - <img src="t60_dev/0019.JPG" alt="" /> - </p> - - <p> - Unscrew those:<br/> - <img src="t60_dev/0020.JPG" alt="" /> - </p> - - <p> - Make sure you removed those:<br/> - <img src="t60_dev/0021.JPG" alt="" /> - </p> - - <p> - Disconnect LCD cable from board:<br/> - <img src="t60_dev/0022.JPG" alt="" /> - </p> - - <p> - Remove those screws then remove the LCD assembly:<br/> - <img src="t60_dev/0023.JPG" alt="" /> <img src="t60_dev/0024.JPG" alt="" /> <img src="t60_dev/0025.JPG" alt="" /> - </p> - - <p> - Once again, make sure you removed those:<br/> - <img src="t60_dev/0026.JPG" alt="" /> - </p> - - <p> - Remove the shielding containing the motherboard, then flip it over. Remove these screws, placing them on a steady - surface in the same layout as they were in before you removed them. Also, you should mark each screw hole after removing the - screw (a permanent marker pen will do), this is so that you have a point of reference when re-assembling the machine:<br/> - <img src="t60_dev/0027.JPG" alt="" /> <img src="t60_dev/0028.JPG" alt="" /> <img src="t60_dev/0029.JPG" alt="" /> - <img src="t60_dev/0031.JPG" alt="" /> <img src="t60_dev/0032.JPG" alt="" /> <img src="t60_dev/0033.JPG" alt="" /> - </p> - - <p> - At this point, you should wire up your programmer according to it's documentation. For me, this was (see: "SparkFun cable pin reference"):<br/> - <a href="http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts" target="_blank">http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts</a>.<br/> - Correlating with the following information, I was able to wire up my pirate correctly:<br/> - <a href="http://flashrom.org/Bus_Pirate#Connections" target="_blank">http://flashrom.org/Bus_Pirate#Connections</a><br/> - And by following that advice:<br/> - <a href="http://www.coreboot.org/Board:lenovo/x60/Installation#Howto" target="_blank">http://www.coreboot.org/Board:lenovo/x60/Installation#Howto</a>.<br/> - (it says X60 but instructions are virtually the same for the T60, with except to physical differences in how to disassemble the machine)<br/> - Note: that last page says to wire up only those 5 pins (see below) like that: 1, 2, 4, 5, 6.<br/> - Note: and then, for power it says (on that coreboot.org page) to connect the power jack to the board and connect the - AC adapter (without powering on the board).<br/> - Note: I ignored that advice, and wired up all 8 pins. And it worked.<br/> - - Here is the pinout (correlate it with your programmer's documentation):<br/> - <img src="t60_dev/0030.JPG" alt="" /> - </p> - - <p> - Connecting the pomona:<br/> - <img src="t60_dev/0034.JPG" alt="" /> - </p> - - <p> - Connect programmer to 2nd computer:<br/> - <img src="t60_dev/0035.JPG" alt="" /> - </p> - - <p> - Programmer has power:<br/> - <img src="t60_dev/0036.JPG" alt="" /> - </p> - - <p> - Now flash the bricked machine using the 2nd computer. in my case I did:<br/> - <b>flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w bin/t60/libreboot_usqwerty.rom</b><br/> - Note: there are also other ROM images for T60<br/> - Note: this is using buspirate as the programmer, so it is flashing the T60, not the 2nd computer!<br/> - Here's my terminal window on the 2nd computer (also the programmer is active):<br/> - <img src="t60_dev/0037.JPG" alt="" /> <img src="t60_dev/0038.JPG" alt="" /><br/> - So, you should see the following:<br/> - -- - <pre> - flashrom v0.9.5.2-r1517 on Linux 3.2.0-61-generic (i686), built with libpci 3.1.8, GCC 4.6.3, little endian - flashrom is free software, get the source code at http://www.flashrom.org - - Calibrating delay loop... delay loop is unreliable, trying to continue OK. - Found Macronix flash chip "MX25L1605" (2048 kB, SPI) on buspirate_spi. - Reading old flash chip contents... done. - Erasing and writing flash chip... Erase/write done. - Verifying flash... VERIFIED. - </pre> - --<br/> - At the end it says "VERIFIED", which means that the procedure worked. If you see this, it means - that you can put your T60 back together. So let's do that now. - </p> - - <p> - Put those screws back:<br/> - <img src="t60_dev/0047.JPG" alt="" /> - </p> - - <p> - Put it back into lower chassis:<br/> - <img src="t60_dev/0048.JPG" alt="" /> - </p> - - <p> - Attach LCD and insert screws (also, attach the lcd cable to the board):<br/> - <img src="t60_dev/0049.JPG" alt="" /> - </p> - - <p> - Insert those screws:<br/> - <img src="t60_dev/0050.JPG" alt="" /> - </p> - - <p> - On the CPU (and there is another chip south-east to it, sorry forgot to take pic) - clean off the old thermal paste (rubbing a1ocheal (misspelling intentional. halal internet)) and apply new (Artic Silver 5 is good, others are good too) - you should also clean the heatsink the same way<br/> - <img src="t60_dev/0051.JPG" alt="" /> - </p> - - <p> - Attach the heatsink and install the screws (also, make sure to install the AC jack as highlighted):<br/> - <img src="t60_dev/0052.JPG" alt="" /> - </p> - - <p> - Reinstall that upper bezel:<br/> - <img src="t60_dev/0053.JPG" alt="" /> - </p> - - <p> - Do that:<br/> - <img src="t60_dev/0054.JPG" alt="" /> <img src="t60_dev/0055.JPG" alt="" /> - </p> - - <p> - Re-attach modem, wifi, (wwan?), and all necessary cables. Sorry, forgot to take pics. Look at previous removal steps to see where they go back to. - </p> - - <p> - Attach keyboard and install nvram battery:<br/> - <img src="t60_dev/0056.JPG" alt="" /> <img src="t60_dev/0057.JPG" alt="" /> - </p> - - <p> - Place keyboard and (sorry, forgot to take pics) reinstall the palmrest and insert screws on the underside:<br/> - <img src="t60_dev/0058.JPG" alt="" /> - </p> - - <p> - It lives!<br/> - <img src="t60_dev/0071.JPG" alt="" /> <img src="t60_dev/0072.JPG" alt="" /> <img src="t60_dev/0073.JPG" alt="" /> - </p> - - <p> - Always stress test ('stress -c 2' and xsensors. below 90C is ok) when replacing cpu paste/heatsink:<br/> - <img src="t60_dev/0074.JPG" alt="" /> - </p> - -<hr/> - - <p> - Copyright © 2014 Francis Rowe <info@gluglug.org.uk><br/> - This document is released under the Creative Commons Attribution-ShareAlike 4.0 International Public License and all future versions. - A copy of the license can be found at <a href="../license.txt">../license.txt</a>. - </p> - - <p> - This document is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
