You are right, there is a partial contact inside the motherboard power pack. you will need an expert to do it for you, but if you are sure you can do it, just try opening the computer system and go straight to the port where the power cord is been plugged you will need a soldering iron and a lead to work on the board, around the port connector, you will see some broken soldering, all you need to do is to resolder the broken lead connection.

My dell 1420 laptop does not startup unless I hold it in my hand and apply pressure to the cassing


Hello,

There is something loose inside your computer. You just need to tighten the screw up. I think you need a technician or a techy friend to do that because there are a lot of computer parts that you would need to check.

MY DELL INSPIRON 1420 WHEN I PLUG IN BUT NOT CHARGING HOW TO FIX IT.


Hello, you may find this to be the fault of the charger itself. Dell chargers have a micro thin communication wire that tells the battery to chage and when to stop charging. But this tiny communication wire within the charging cable is very fragile. If it breaks inside, then the laptop battery will not recieve the signal to make it charge. Replacing the laptop charger may be your solution. But it will need to be another Dell charger compatible with your laptop

Will Not charge with brand new a/ power cord it will at times power on if moved the right way but quickly powers off if moved the port inside looks to be fine But I hear there is a pin type thing inside...


The problem is with the AC adapter itself and is a very common problem with Dell AC adapters. My suggestion would be to get an aftermarket AC adapter that can be purchased on eBay as the Dell adapter is around 100.00. You can pick up an aftermarket one on eBay for around 20.00. The problem is a resistor inside the AC adapter that senses when a Dell branded adapter is inserted. What happens is that the resistor will get damaged and since it doesn't recognize the charger as a Dell branded one anymore it won't charge. However it will still run the laptop as long as it's connected. A lot of aftermarket AC adapters bypass this function and work perfectly fine.

Inspiron 1420 dell says plugged in not charging


Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Dell Laptop -Inspiron 14220 Battery Not Charge(plugein,No charging)


There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

Battery wont charge unless I jiggle the cord


Hi,

This is due to a faulty cord or a damaged power inlet on the motherboard. Hope for your part it is the cord. Try a new power cord and if it doesn't work I'm afraid you might have to replace your motherboard...

Cheers

Laptop Not Getting Power


There could be a number of resons for this. Some thoughts:
1) Was your laptop working fine before you bought this new adapter? Eg. did it work with the previous one.
2) Are you positive that it is compatible? You should check all the power ratings against the old adapter (voltage output, current output).
3) Make sure the connector that plugs into the back of the laptop is a perfect fit. Connectors have a + and -. The outside metal ring may fit, but the inside 'pin' may be too small and not making contact with the receving part of the laptop.
4) Make sure that the connector inside the laptop has not broken. Easy way is to get a pencil with eraser and stick it in there and wiggle it around. If it moves sustantially, you may have some connector pins that have become unsoldered. If so, you need to get this fixed.

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.
