[EN] Fixed: freezing & random bluescreen
I had several problems with my laptop after I dropped it. Fortunately, the laptop was okay during my paper presentation. :) However, the following symptoms were not tolerable.
- Freezing (no response from OS)
- Blue screen (being unable to collect a full memory dump)
- Even the screen shows random color pixels occasionally.
The above symptoms happened when the laptop was lifted, implying that it is due to the hardware problem (perhaps poor contact). I tried to disassemble/reassemble the machine several times to figure out the root cause, but I couldn’t find any strange thing. I almost gave up and finally looked at the memory slot. And I eventually found a super-tiny sticker paper sitting in the slot… lol
(Conclusion) A trivial thing is not trivial!
