Today it was necessary to go into the BIOS on the Lenovo IdeaPad 110-15IBR laptop (80T7), but when you press all the keys that are usually used to enter the BIOS, the laptop did not respond and the system continued to boot.
As it turned out, in the BIOS of this Lenovo laptop model, the HotKey Mode function is activated as standard and the functional keys are activated instead of the F1-F12 keys.
Therefore, to enter the BIOS, it is necessary to press two Fn and F2 keys simultaneously, if HotKey Mode is disabled, then simply F2.
On the test I’ll take the H805GPFD board with 16 GPON ports and install it in OLT Huawei SmartAX MA5683T without shutting it down. After inserting on the board, the RUN / ALM indicator flashed red and literally a minute later green.
