I don’t see how you could have damaged the power button. All you can do is take it apart again but re-assemble very slowly and carefully watching what you are doing. Take your time, look at and think about everything you are doing. Make sure all ribbon cables are connected correctly and carefully (probable cause of problem) and those that need to be folded away so there is no stress on the mainboard.

Hi Loli, It depends on which part of the wire you are moving. If it is near to the charger itself then it is the wire itself that is defective. Replace charger. If, on the other hand, it is close to the connector that plugs into the Chromebook it self then it could be the connector on the chromebook that is defective.

Another one bites the dust. These WD, etc. external drives. People stop buying them. Just look at how often this problem comes up on IFIT. To repeat, buy separate SSD/HDD and external case. Both parts replaceable. Much more reliable and easily upgradable. Having said that, open up the case to see if the HDD has a standard SATA connector. If it does you are lucky. Just buy a separate external case and install drive. If it still doesn't work then the drive is defective but you may be lucky and Photorec will work well with the new external case . The question is, is it the WD controller or the drive itself that is the problem - or both?

The hard drive is either defective or the connector is not completely connected. First remove the battery: https://support.lenovo.com/nz/en/solutio...-68269 and then the hard drive: https://support.lenovo.com/nz/en/solutio...-hard-drive-removal-and-installation-thinkpad-x60-tablet-x61-tablet and YouTube video: https://www.youtube.com/watch?v=QSjNHUeM...

These name branded external drives are the worst possible choice. Always, always purchase a SEPERATE case/controller and hard drive. Again, why? Often the branded ones have the drive’s circuit board and the USB port imbedded in the same circuit board. If that circuit screws up you are often lost. The component solution (like a good hi-fi sound systems) allows you to easily take the drive out, if the USB part goes bad, and recover your software in another system or case. If the drive dies replace it or upgrade to SSD or larger capacity. A no brainer!
