HP Laptop does NOT boot without battery
I have an HP laptop that has an old battery. The battery is working but lasts for short time.
However I don't need the battery as most of the time I am using it plugged. I tried to remove the battery and run but it does not run without battery. I purchased a new battery (not original, since HP stopped producing old batteries) from this link but it does not boot with it (even it is the SAME 7.7V - 41W). I now returned the old battery and the laptop is working. Can I somehow remove the battery and run the laptop without it? (maybe plugging the power cable directly to input caple without going through battery?)

You need the battery in order to start the laptop. There is no practical way to bypass the battery if not installed.
Leave the old battery in so you can use the laptop. Depending on the computer, the charger is normally designed to charge the battery and may not power the computer by itself. For laptops, even if possible, it is not a good idea to run without a battery. That is a general comment for completeness as your machine does not start without a battery.
Look on eBay or Battery sites for an OEM HP Battery so that a new battery will work. A third party aftermarket without the HP chip circuitry in the battery pack will not work.
Good luck
7Odd, I've had this happen with a Lenovo laptop, not with HP. They are usually less predatory about their hardware.
To answer: A solution is to replace the motherboard. On the usual sites, it's around 50 euros (=70 USD) for an old system. A cheaper solution is replacing the DC Jack cable first, the internal cable which receives the plug and connects to the motherboard.
