wow....... that is a bad thing to happen now in this RAM climate. you (and your loyal laptop) have my condolences
if it is not soldered in it may be a good idea to grab some of that ram out of the device! lenovo was doing a good for value range of gaming laptops a year ago 40 series and now some 50 cards, but their prices have gone up a lot. some of their "legion" series laptops are on sale (not the hand-helds), but what i saw was fifty or sixty dollars-so over your budget.
as MattaMus11 (how in god name do i tag someone

) said it is very possible for RAM to just keep going up...... many manufacturers are starting to put less or even sometimes older ram sticks in their consumer products..... some desktop computers pre-built have even been shipping without ram at all i have seen.
if you saw my bank balance you would know for sure i am not one to give financial advice

but it may be a bad idea to wait too long.
