Laptop Precautions
--------------------------
Dear Sir / Madam [{0}],
Greetings from FOSSEE Laptop team.
Recently, it has been noticed that the users of some of the FOSSEE laptops are encountering USB power issues, which could lead to damage of the USB ports.
On investigating this issue, we found that:
1)
The USB ports on these devices are capable of providing ONLY limited current (mainly designed to serve mouse, keyboards, sdcard readers, pen-drives and other such low-power peripherals ).
2)
If the USB port(s) is damaged, it could also result in a non-functioning touchpad as it is internally connected to the USB hub.
We have relayed these issues to the vendor for a possible fix. We will update you on the same once/if a patch is made available.
Meanwhile, please follow the below instructions to prevent this issue from occurring:
1)
Do not connect high-power demanding devices like phones/power-banks/mp3-players to the USB port. Do not connect phones for even data transfer.
2)
Do not connect USB powered hard-drives (external powered USB data hard drives could be fine).
3)
Use external power supply to Arduino or similar boards while interfacing higher loads (motors, GSM shields etc).
4)
Do not connect USB hubs to chain-load peripherals.
5)
Any USB device which demands high power from the USB port should NOT be connected.
