Hello there tech guys..

i really need help for my annoying problem.. my laptop which is lenovo G450 suddenly No power
what i mean is.. when i open my laptop i can get to desktop without anything problem... like beeps( sounds )
but then.. i think when i open such as youtube.. work for the meantime then suddenly like i don't have a power at all
in simply way the laptop is brown-out ..

i can't use english language at its best so i'm sorry for that..

is this maybe i need a thermal paste? i had done the following steps.

1. FRESHLY FORMAT MY OS (still not fix the problem)

2. CLEAN THE FAN (even it's not really had a jungle dust on it, doesn't work either)

3. USE ANOTHER POWER SUPPLY (ADAPTER FOR LAPTOP) , (still has the problem)

PS.
even i have a battery or not ... same problem..


HOPE COULD YOU GUYS HELP ME WITH THIS PROBLEM

MY LAPTOP IS IN GOOD SPEED.. I MEAN IT'S NOT LAG OR ANYTHING JUST THE SUDDENLY NO POWER

thanks in advance!

A computer shutting off is typically an indication of a hardware fault. Most common causes would be the power supply or motherboard.

If was overheating, you would be getting an alarm (ie: beeping) as it shuts down.

like i said .. no beeping at all.. just if your're using desktop just unplug it .. so now you can understand what am talking about.. feels like that.

I have rarely heard a laptop give an alarm when it overheats. Overheating would be my prime suspect.

Check the fans and blow them out with a can of compressed air. Listen for any fans spinning and air blowing out of the laptop where the vents are, check to see how hot the bottom is as well. Easy to do and a good first step.

huastro, my post said there were two reasons
hardware or display driver cache.

The three reasons you posted about I said did not apply to your situation.

I think you need a better translation program. :D
