Repair Dell 5G971 LCD AC Adapter, make it easy
Your computer can be adversely affected by the problems that its laptop ac adapter encounters from the wall outlet or power source. One problem the Dell 5G971 LCD AC Adapter might encounter is a blackout, which is a loss of power that can occur because of a blown fuse or damaged power line. Troubleshooting Dell 5G971 LCD AC Adapter is not that difficult provided if you know how a laptop lcd ac adapter work. If you are unsure of how to troubleshoot Dell 5G971 LCD AC Adapter, I urge you to read this article, and I will continue to post more laptop ac adapter articles at that page and hope you could drop by more often to check out my blog.
The adapter pack module type is easy to diagnose because you can replace another working unit just to make sure is the power pack that giving problem. You may also use an external Dell 5G971 LCD AC Adapter to power up the LCD to confirm if the power pack is faulty. If you do not have the external laptop lcd ac adapter, you can always use this method to isolate the problem especially the symptoms are no power, low power and power blink. Using the rear light bulb (12 volt) from a car and connect it to the power pack output jack. If it light brightly then the power pack is okay. If it blink or dim the power pack have problem. Why have to use this method to test it? Because, if there are components shorted or leaky at the LCD main board, it will affect the Dell 5G971 LCD AC Adapter performance.
From experienced, most of the LCD ac adapter problems whether in the power pack or built into main board were due to the failure of electrolytic capacitors (most probably due to heat) in the primary and secondary section. Most of the capacitors have a high ESR which causes the Dell 5G971 LCD AC Adapter to produce low output, blink or no power at all. Typical value electrolytic capacitors in the primary side are 47 and 100 micro farad 50 Volt and the secondary sides are 1000 to 2200 micro farad 25 volt. Sometimes you can see the capacitor top casing became bulge and the sleeve that covered the capacitor casing turned into darker color like brownish.
