Question about HP Compaq Evo Notebook N600c

1 Answer

My compaq evo stopped working. For about two weeks I had a buzzing where I place the power cord. At that time periodically the whole thing would shut down. Also now it will not start at all and the battery stopped charging.

It sounds as though you may have either blown the power supply, or burned the power circuit on the motherboard. That buzzing sound usually indicates an electric arc, where electricity passes through open air from one contact to another; In this case, it was probably caused by a loose or broken solder connection on the laptop's power jack.

If you can get your hands on an identical or equivalent power supply, test it with your laptop. If it works, then the power supply just needs to be replaced.

If not, try taking the battery out of your laptop, and plugging it in again. Sometimes, when a power supply burns up, the battery will discharge, rendering it inoperable.

Hope this helps!

I have an old compaq evn n610c. I had some problems with it for a while where I had to wiggle the power cord a little to get it to power on with the cable. That worked for a while and then one day it...


Hello,If the battery stops charging when you wiggle the power plug inside the jack, either you have a bad power adapter (test it with a voltmeter) or the power jack((DC jack)) is broken or loose.
If the power jack is broken you can replace it if you know few things about soldering;)
If the power jack is not broken but loose (not making good contact with the motherboard) you can re solder the old jack without replacing it with a new one.

Powered off.


Any beeps when you turn it on? unplug everything and then plug it back in. Make sure the monitor connections are good and that you have it turned on. Again make sure it's turned on. Sometimes it's the simple stuff. Was the monitor working well before it failed? Do you have a video card?
Remove the battery, AC, count to ten and try one last time?

Dell Inspiron B130 wont boot


First remove the battery from the PC! Leave it off for a short period of time! about 2min. This allows the computer to erase anything in temporary memory. Place the battery back onto th PC and try to boot it up. The other thing you can do is boot the pc up with just the power cord in place. See if it boots just from the power cord. Sometime the batteries from dell causes the whole entire PC to become unresponsive.
