Replacement Laptop Power supplies

[Jumping Anaconda]

I think my laptop power supply is on the way out. I reach this conclusion because:

1, For the last month or so when I was running my laptop on the power supply with the battery out, the laptop was very occasionally spontaneously switching off. This behaviour stopped with the battery plugged in.

2, About a month ago there was a single incident of me running it with the battery in, and although the battery was displayed as charging, the charge level dropped down to zero and the machine switched off, indicating it was actually running on the battery.

3, The situation in 2 has become a frequent situation this week. Running less applications, and switching to a power mode with a very low power requirement seems to trigger the battery charging again.

4, Wiggling the cable in the socket seems to make no difference.

5, The laptop appears to charge up the battery fine when it is powered off.

From this I am concluding that the power supply is on the wonk and no longer able to carry the load of powering the machine and charging the battery at the same time, and is unreliable when solely powering the machine.

So, I am looking for a replacement power supply. It is an HP laptop, but I do not fancy getting a straight replacement. I have seen some of the universal adapters, but is there a real quality replacement I should go for?

Any guidance gratefully received.

I find that the universal ones arent much good normally and end up melting either the connector on the adapter or the connector on the laptop. I usually spend a little extra and find a genuine replacement

check out the other bay.. thats where I get mine, cheap and effective, and most ship worldwide. They arent name brand, but they get the job done

If you can open the charger, check the capacitors. They are the most wearing thing on those and the major fail culprits.

Our laptop power unit went dicky about a month ago and would work/charge now and again.

It turned out the cable had broken on the inner core.

I bought a psu and battery from the usual cheap Hong Kong location from ebay, and they died both within a few weeks.. I bought a heavy psu here second hand meant for a desktop that had the right voltage and soldered the old wire to the new after that.
