Question about Dell Inspiron B120 Notebook

1 Answer

Have a old dell b120 laptop, I just got a new ac charger, the 3rd green light will come on steady, but the laptop will not turn on. if I move the laptop, the 3rd (light from left will slowly blink green, then it might go out all togather. Any thoughts? AC jack in back of the laptop doesnt seem loose, but I suspect thats the problem. Any suggestions?

HI There,

"move the laptop" is pretty much a dead giveaway that it's the DC Powerjack, just as you suspect. Even though it may not seem loose, its interior connection on the board is probably just enough compromised to cause the lack of power supply.

I used to solder these myself but now send them out to several different vendors on eBay without problems. Of course, your issue will be whether to spring for the 80 to 100 bucks for the jack replacement or move to a newer rig.

Best of luck to you.

There could be many reasons for your problem from shorting something out while the motherboard was exposed to over heating the area at the power jack. My first and simplest suggestion would be to remove, and re-seat the memory modules. Are you sure you have good solder contacts on the jack you replaced?

My Dell Inspiron B130 will not turn on


The battery is critically low, indicating that it is not getting a charge from the AC adapter. If the system will not power on from the AC adapter, then the motherboard power connection is suspect.

Motherboards are about $100 on EBay

Dell inspiron b120 laptop won't power up


i dont know why dell did this but you have to have battery to run your laptop. the ac coard charges the battery which runs the computer. I really know why but i dont like the configuration. it is so the power is clean to your computer and so the can have less parts in the laptop you need to get a new battery

Old battery not charging plug in charger green light goes out


If the system will not power on, and the LED on the AC adapter goes out when plugged into the system, then the most likely senario is the motherboard has failed. Remove the battery, Wireless card, Drives, RAM and connect the AC adapter see if anything changes. If no change, the MB is most likely bad.
