Hi guys, I'm sorry to write in such an old topic, but there are no professional hp 2560p specialists anywhere else on the Internet. I bought an i7 2860qm for hp 2560p, after installing it inside, the bios does not even boot, caps lock flashes five times, the screen is black, and the cooling system is running at full capacity. Used standard 19.5V (3.33A) 65W power supply. Windows 10/x64 - ssd (mbr). the latest BIOS version is A.66 The battery is removed from the laptop and is powered only from the mains. I tried to reset the bios before replacing the processor using the motherboard battery. it was reset, but the laptop never turned on. Tell me, what could be wrong? The I5 2540m works perfectly. p.s. sorry for the mistakes in my English, I am writing through an online translator)
