Hello, my compaq 325 doesn't boots when i try to
on it , it gives 5 times light on capslock key so its
an motherboard issue so i had been to hp service
center and they told its power ic has burnt and
they repaired after running few days again in got
same problem so i had visited some local repair
shop they also told again your power ic has been
burnt and i asked the reason for it amd they told
its caz of overheating, according to my knowledge
power ic burns caz of power fluctuations, but i am
not an laptop technician so i want to know is it
becaz of overheating or becaz of power
fluctuations.

Overheating would be my first guess.

 

Why do you suspect power fluctuations? Where are you located?

i guess the real question is what is causing it to keep overheating and burning out?

 

you using it on your lap/bed cover and blocking air flow?

 

could it be a power fluctuation of some type causing it to overheat and keep burning out? yes i think it is possible some other component may be faulty causing the power ic to burn out.

@ SpywareDr :- i am residing in India, i do suspect power voltage fluctuations caz heating will be on gpu and cpu and i always use to view their temps. they will be under 60°C.

my question question is why do power ic is burning, local technician told power ic is burning caz of overheating of lap, but i keep it full ventilated, change thermal paste regularly and clean it regularly, but when i went to hp service center they told power ic has been failed because of voltage fluctuations. i can't figure out which one is the real reason, if its caz of overheating than i can put a new heat sink and fan or if its caz of voltage fluctuations i can keep any voltage stabilizer for it or else if weak MB is the problem i can change full MB.

if its voltage fluctuations, i guess how can it be possible caz for lap we use adapter and it gives voltage how it is rated to give, or m i wrong and it just bypasses if over voltage comes from main supply?

sorry it's been over 30 years since i studied/worked with electronics, so have no answers for you or any advice on how to diagnose where the problem may be, just saying it is a possibility and something that i'd definitely look into if it burns out a 3rd time.
