Hello!
I've recently bought cheap Lenovo Yoga 720-13IKB with possible RAM problems. The laptop worked but when it filled about 20-25% RAM (out of 16GB) the system shut down with an error (BSOD). Before buying new motherboard I've thought I'd try to reflow the RAM because it worked strange..
For example MemTest only showed errors, it couldn't boot from USB (except Linux Mint) but it booted to Windows normally after installing it on a different PC, etc.
I did the reflow on the RAM at about 215°C for few seconds on IR light reflow station. After that the laptop turns on for 2 seconds, the power light and backlight, then shuts down and restarts. When Charger and battery are present, the charging light blinks 3 times.
I've tried disconnecting everything from the motherboard and just plug in the charger but no luck.
Could it be I've shorted the RAM or fried the chip - or something else?
Thanks!
