Dell Latitude D520 Power Problem

by sameerkanal / March 25, 2009 3:29 PM PDT

I have a Dell Latitude D520 and the power abruptly turned off a few days ago and won't come back on. The battery has been dead for a few months so I've been running it on AC power and that's worked just fine for a while but about 4 days ago it died. I unplugged everything, removed the battery, and put it back in/replugged in everything and it still didn't work.

When I plug the charger into the wall the green light comes on but when I plug the other end into the computer the light goes off. I've tried this with two chargers now. Is the problem with the charger, the battery, the power supply...? Please help. Thanks.

There are a few methods used to fix these.

We have the technical direction which you may not find useful as I note that we use our VOLT METER (got that?) and then we move to the old CHANGE A PART AND TEST method.

Frankly at the age and story I would be shopping for a replacement laptop. Even a refurb will cost less than any shop or service center.

But there are files...

I need things that I have placed on the laptop since my most recent backup (which was a while ago) so at some point I will need to fix the laptop. Is it a charger problem, a battery problem...? What specifically needs to get fixed?

As noted.

To sniff out battery or charger you use your voltmeter. But if you ask then this means you are not the person that repairs hardware. You have to move forward to replacing parts till you find the bad part.

The good news is the parts are very few. We don't need a battery so that's set aside. Same for the hard disk, CD/DVD drive and then we're done to the laptop and the wall power unit. We swap out the cheapest part first. As to the laptop, the usual failure is the motherboard. These are rarely repaired.

As to your data, if you left it on the hard disk, pop the hard disk into some other machine to get at your files.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
