Question

Power brick has green light, laptop does not

I was about to go to bed and I found my laptop was dead. I saw that the laptop did not have a green light for charging.

The brick had a green light on it. I was able to have it run off the battery for a little bit, it was at 2% then died.

Now it is dead dead.

I unplugged it from the wall, took out the battery, pressed the power button for a good minute, then plugged it back into the wall and nothing.

Is the motherboard fried? or is it just the power port?

I did plug the brick into another pc and it booted up fine.

Since it ran for a time on battery

In reply to: Power brick has green light, laptop does not

The odds it's the power jack increased by you asking. Is there something about the power jack that doesn't feel right?

There's only a few parts to charging the battery (charger, motherboard and battery) and for the more technically inclined they can change the jack and hope.

That's what I thought

In the past it's day 3 years ago I had the power port resoddered on it at the shop, the jack "feels okay" maybe a little loose it's not as snug but even then it worked.... I'm guessing it gave out?

At 3 years ago it was repaired.

How old?

I have a decade old Compaq R300 that I'm going to change the jack on for the very first time. But I know it's the jack so it's going to happen. Long reason why. Something about our office and keeping a pair of XP machines alive for paid legacy support.

No problem

I Googled it hoping it would work, could be cmos battery it's rare I know but the laptop is 6 years old. I'm just getting to get an idea of what could be wrong before I take it to the shop tomorrow after work.... Free diagnosis just gotta wait 3 days

Actually 6 years is iffy territory for a CMOS battery.

In reply to: No problem

If I was to go inside to replace the jack, it's time for a CMOS battery.

It might be the motherboard is died

In reply to: Power brick has green light, laptop does not

I guess the motherboard is died since when the power port is broken you could still able to power it even though you cannot charge it,

Check the 3-things

In reply to: Power brick has green light, laptop does not

Battery, AC charging port and AC charger as stated are typical areas to inspect. You stated it was already fixed some 3yrs. ago., maybe problem returned. Also, if the battery is that old, replace. Alas, some chargers can have broken wires, though the grn. LED is lit, means only AC power is present. Also, the wiring typically at fault is the other side going to laptop connection. If possible get another AC charger(borrow) of similar type. While AC charging ports themselves can break by solder or loose wiring inside, only teardown inspection will do. If the battery is already too old, get another one. Alas, if the mtrbd. itself is at fault, then another used one or laptop itself(same model), maybe Craigslist or eBay.
