Looking for a laptop charger

[PatchTuesday]

So my mom's laptop decided it wouldnt power on today.
Did some troubleshooting in the form of unplugging the battery and trying to start it up with only the charger connected.
Theres no sign of life at all.plug the battery back in,try and power it on,which gives some light effects and dies.
Plug the charger in,same story.Still no life.

So the battery may cause the brief lighting.Im hoping the charger is busted and not the laptop itself.
Anyone know where i can get one of these that wont cost an arm or leg?

HP 740015-001 or
HP 45W Smart AC Adapter

A quick google search yeilds some rather dodgy results

You should test if the charger still works by using a multimeter.

If it turns out being the charger - the cheap replacements have worked for me. I bought on Bidorbuy to get local stock. The mains cable on a Chinese one disintegrated... so just had to swap that out.

You're looking for something thats 19.5v and 2.31A or above, anything with the same voltage...

eg 19.5V / 3A is also fine.
19.5V / 5A is also etc


Check with a multimeter first though to make sure.
Inside is positive (red probe), outside is negative (black probe).

I disagree with other posts, it is probably not a charger, but short circuit in the laptop itself.

Try other charger, but you must be prepared for the worse.
If you don't have another charger, meassure the output voltage from PSU, as indicated in above post. Battery gives a blink, as it can supply plenty of current (before over current protection kicks out). This is how I see this story. Still repairable, but not many people can do it.

You'd be surprised at the number of failed chargers with faulty caps I've seen.
Cheap fix when you have low labour costs and a bunch to fix, but usually easier to replace the charger for end users.
