I DE-BRICK Y410p I managed to un-brick my y410p. All you need is a screw driver. I bricked my y410p after I undervotl-ed my CPU. Yeah, I didn't know it would brick the laptop. All the information online told me there's no simple fix. There are two methods I found: 1. Replace with a different CPU and it will reset the settings. Change back to the original CPU afterwards. 2. Swap the BIOS soldered on the mobo. But the good news is you can un-brick it easily. I'm not sure what did the job. But all you need is a screwdriver. In short, try to reset the BIOS settings by using key combos: press F2 during boot, then F9 enter, F10 enter. Then remove all extra device, including RAM, HDD, WiFi card and UltraBay device. Then let the system run for 5 min, and then connect the JCMOS2 connectors while the system is on. Plug back everything and it's done. Here's what I did. 1. Try to reset BIOS settings by key combos: press F2 during boot, then F9 and enter, then F10 and enter. Shut down the system afterwards. 2. Remove Ultra Bay device, battery (NOT the one soldered on mobo) 3. Remove the back cover and then remove the RAM, WiFi card, and all SSD/HDD. 4. Plug in the AC power cord and start the system 5. The system will keep turning on and off. Let it run for 5 min 6. Connect the JCMOS2 connectors with a conductor (e.g. copper wire) for many times while the system is on 7. Turn off the system and plug in the RAM 8. BOOM! IT BOOTS! 9. Then reboot into BIOS and reset the settings manually by pressing F9 and enter. 10. Save and then shutdown the system 11. Plug back everything into the system. DONE! Here's a weird thing. It actually didn't reset all the BIOS settings but only OC settings. I had overclocking disabled after all the steps. But other settings remain the same as I last modified them . So you may need to reset the BIOS manually to make sure everything works fine.
