Ive been looking for a gaming laptop for a very long time (i’m a university student) but my budget isnt that high, recently found a blade 17 pro with an i9 11900h, rtx 3080 16gb and 1tb ssd, paired with the 4k 120hz ips, owner says its in good condition but he removed the battery because it apparently overheats when playing in 4k ultra, https://9apps.ooo/

Is there anything i should be worried about other than the battery before buying?
