About half a year ago the laptop began to reboot with black screen and message - "hard disk error", and hdd died after a coupe of weeks. I bought Kingston SSDNow A400 240GB. I thought everything was fine, and now my laptop is repaired, but it began to reboot without error screens or messages, just reboot, and sometimes it reboots with the screen off, and caps lock signals 3 flashes.. After replacing hdd to ssd, CPU began to warm up, and sometimes software aida64 extreme in stress test mode shows throttling. I also noticed that when the power is connected, the indicator located near the charging socket signals connection / disconnection, this is not happening when the battery is removed.
