I have idea repair dead Surface pro 3 but I need help
Hi guys
hope if anyone could help
i have an idea that i think that could possible wake up a dead SP3 if the problem is related to battery issue
the last state for battery after several tries to open it was indicate 0% then i connect it to charge and shut it down while i don't know that i must let it charge before shut down so now it doesn't turn on again
my SP3 now is totally dead and Microsoft confirm that the only way to repair it is to replace. so i would try if i could solve it without teardown the tablet
by try and error approach
so is there one have a clue or have an open SP3 tablet could help me to find a way
My idea is to check if i could wake my lithium ion battery from outside ,as i read something about boost a sleep battery from this article:
(http://batteryuniversity.com/learn/artic...)
- Some Li-ion chargers (Cadex) include a wake-up feature, or “boost,”
- Boost applies a small charge current to raise the voltage to between 2.2V/cell and 2.9V/cell to activate the protection circuit, at which point a normal charge commences.
so in the video link below i think that what get happen to this battery for example:
(https://www.youtube.com/watch?v=WFd1CXbR...)
as the USB charge is a low current than the normal one
(and there is more than one example for this problem can be checked on youtube)
so if someone could tell me his experiments to check and analyze what happen for every pin that is connect to battery and what happen when change the volt or amber to its corresponding on battery side
all what i believe that it is 4 cell(the 6 charger pin on each side.)
and that the polarity is opposite as it could be connected in either way
wonder why the number of the charger socket is more than the pin of charger
so then i would try if i could signal the battery to wake it up so i wont replace it through Microsoft for new one
thank you everyone
Questa è una buona domanda?
I am actually seriously planning to hack a connection to the battery and make an alternative external charging mechanism , I also have a degree in electrical engineering, I am on my way to my 3ed bricked sf pro 3, multiple chargers, new type , old type, alternative ones, driver updates, battery not charging, power-supply not detected, I have been trough it all. I am so fed up by engineers that ships unfinished product and messy driver updates. On my current SPro , the battery was good for 6h+ last week , but is now dead due to an "update" and not detecting the power

We solved our charging problem by docking the wife's surface and using an icharger when traveling. However, docking it too long will lead to battery swelling. So collaspse the docks to charge and extend them when its charged. This has worked great for 3 years and counting.
