Month: July 2017

Updating this blog after a busy weekend. I came into possession of a Lenovo Yoga 2 Pro ultralight which could not boot up. The BIOS showed the stock 256 GB SSD was not recognized – uh oh not a good sign.

Quickly went to Sim Lim to pick up a replacement (and one with a larger space) mSata SSD – Samsung  850 EVO 500 GB and prepared for the operation.

Something at the back of my head was stopping me from replacing the SSD, so I thought to give another spin on the repair bandwagon. After some mucking around, I managed to resuscitate the Y2P, not after downloading a Windows 8.1 ISO (its free to download but you will need to key in a serial number if you are doing a bare metal install) from Microsoft.

The magic is found within the Repair Options -> Command Line in the Windows 8.1 thumbdrive.

c:\> bootrec /FixMbr
c:\> bootrec /FixBoot
c:\> bootrec /RebuildBcd

The Y2P started to boot up normally. I was able to log into the Windows 8.1 desktop.

All’s well.

Went to the library to study in the morning, followed by lunch at Fortune Centre and coffee at Mellower (hipster joint, I know).

Recrimped 1 x RJ45 cable and researched for a wireless mouse to replace the two I currently have. Both wireless mouse have scrolling problems (missed scrolls)

Just as I was about to hit Pay on the online website, a thought came across. Why don’t I try cleaning the scroll wheel on the mouse? So I gathered the tools:

1. Screwdriver,
2. Denatured Alcohol,
3. Can of compressed air.

Opened up the mouse and removed the scroll wheel assembly. Surprisingly clean, despite it going places and more than 8 years old. (Dangling white connector – I’ve removed the two-wire connector from the base PCB)

Removed the scroll wheel and wiped the wheel slits clean. The slits triggers a counter in mouse programming to keep track on the number of clicks, thereby translating it to scrolls.

Did you note a possible JTAG header where the ribbon ends? 🙂

Cleaning the scroll wheel with Denatured alcohol on cotton buds and a few blast of compressed air helped to remove the minute debris stuck in-between the slits.

Note the white connectors from the outer shell connected back to the base PCB. A quick test after cleaning and saved another $40 under 10 minutes of work.

Very Naise.
