I have the problem that my Lenovo X230 Tablet does not start. The display remains dark and I get a sound code like "= - - - - =" (where "=" means long and "-" means short).
I had this the first time years ago after opening/closing my laptop (e.g. inserting WWAN card, new keyboard, ...). The problem always disappeared after opening/closing the laptop again ... and basically never reappeared for years.
About two weeks ago, the issue became more frequent. I assumed the problem is related to the two grey cables that go to the display and I could fix the problem by wiggling the cables/connectors under the keyboard. The issue became so frequent that I did not put in the screws of the keyboard any more ... so I could just quickly wiggle the cable and be done.
Starting from today, I cannot start the laptop any more. The display always stays dark and outputs this sound code.
Here is a picture of the two grey cables I mean: https://pasteboard.co/IUA7M6f.png
As you can see, the right cable seems to be a bit broken. Maybe is has been squeezed in the past.
Can this be the problem?
- What does this sound code exactly relate to?
- What does this cable exactly carry (and what the other)?
- Can the issue be on the broken cable?
- Is there the chance of getting this cable without replacing the entire display unit?
