Help Lenovo Yoga 2 Table 10 HD+

[Seamus2013]

I have a Lenovo Yoga 2 Table 10 HD+. When I use the supplied short charging cable it will fully charge the tablet. I bought a 2m cable and with that it will only charge up to 85% and the charging light goes out. I complained to the cable supplier and he sent another. That one does the same thing except stops at 96%. Both these cables were said to be for the tablet.

Is this a problem with having a long cable in that there is too much of a volt drop, or a problem with the charger.

I would appreciate any help.

Thanks
