Is it possible that the laptop charger can not power the motherboard?

Question

Iron

Good evening!
Faced such a problem, after installing Windows on a laptop (by the way, it is already 6 years old), after a while the computer stopped loading normally, when I press the power button, the indicator is on that the computer is on but the screen is black. I played around a little and poked this button and lo and behold! It started up, but not everything is so simple, it starts up, but the hard drive and the cooler simply don’t work, that is, the motherboard cannot find the drive, I got even more courageous and started experimenting when I poked the laptop in such a “non-seeing state” and back inserted the railway and the computer worked fine. Bios found the railway and Windows booted up, but the cooler did not start working. I have an assumption that when the motherboard starts up, it simply does not have enough power and it cannot detect the railway and start the cooler. By the way, I regularly clean the laptop every six months and change the thermal paste. So, can there be a possibility that the charger just broke down and cannot power the computer normally? (And yet, I thought that it was worth cleaning the railway to zero and installing Windows back, and that's what I noticed when I installed Windows, the battery ran down during recharging, that's actually because of this, I began to think that the problem was charging .. .)

Answer 1

Maybe such a hat, yes.
Dried or leaking capacitors are likely.
The solution is to measure the voltage under load.

Easily with frequent disassembly, internal cables / connectors / boards could be damaged. Now it works like this by chance - either there is contact or not.

Answer 3

Is the battery still alive? Does it hold for a few minutes?
Try without charging, turn on the laptop on one battery - everything is fine, turns on, loads ?.
Then the charger for replacement or repair. It happens that the charging is "dead" and the laptop slows down on it, the battery is charged only when the laptop is turned off, etc.

Answer 4

By the way, I regularly clean the laptop every six months and change the thermal paste. So is it possible that the charging just broke

It's like in that joke:
- I feel so bad after yesterday!
- What happened yesterday?
- I drank two bottles of vodka and ate a pie. Perhaps the cake was not fresh.
I opened my laptop for the first (and only) time after 4 years of operation only because I had to replace the power connector.
