Hi, This is an Acer Aspire 4738 laptop with cpu area overheated creating intermittent os hangup. I had changed a new cpu fan and apply new thermal paste but the hangup is still there. At the back part of the triangle cpu area, there are 3 smd tantalum capacitor with marking of 330 on first row and 08D1Y on second row. Not too sure what voltage rating are those caps but i suspect 330uf. I tested them by desoldering one leg off and esr reading is about 17Ω… which is way too high. Does anyone know what could be the voltage rating like is it 2.5v or 6.3v?…. I have been searching for schematic or parts list but unable to find. I think i need to buy replacement cap for those 330 but unsure of the voltage rating. Please help. Thank you.
@mikey5791 , Did you try searching for the schematics using the “board number” of the motherboard? Just curious as to what is the maximum capacitance that your meter can measure? I have read that tantalum is always in uF but not sure about this as you can get tantalum <1uF so how would they mark it on the case?
