UPDATE: Okay... so I went and got me a YiHUA 8786D I 2 in 1 and a Wanptek DPS3010U so I can continue...

I cannot for the life of me get the stupid Current Sensing Resistor off the board. I'm trying with the hot air (BTW, first time using one) and after finally trying my finger on the surface, realize it's just not getting hot.

With the hot iron I am able to get the lead free solder to adhere to the ends of the resistor but apparently not quick enough to try to get both ends to flip it off.

So I will have to get some type of heat sensor to verify my temperature...

Okay, got a bit busy due to the heat. Haven't been able to tinker some more. Will do all the recommend soon and post update later tonight, if not tomorrow for sure.

Okay, I'm assuming this is PR9794 on the schematics right? Check ground to both side of the pads.

I see that one side goes to the +19VB side where more than likely the short will be....

Okay, I have seen videos from Luis and Northridge fix on how they do that and understand the method. I do not have an adjustable power supply or thermal camera. So on the list of items to purchase.

Yeah, I want to narrow it down to the point where I can declare it DEAD or send it off to a shop if its a replaceable part that would require a hot air machine, also on the list of items to purchase.

EDIT: If, and when I do get one, where would I solder the end to?

I measure 2.7Ohms of resistance...

I have the laptop in the title and have had it for about 5 years. Was mine and shared it with my kids for about 2 years, then a year of just the kids and last year just my son. He plays on it about 8 hours a day. We regularly make sure to clean out the blower and heatsinks.

About a year ago the screen started to act up. Sometimes coming on, sometimes not. Sometimes "bowing" the screen would get it going. About 8 months ago bottom side of the...

Hello All! I'm from the Bay Area in California. Started getting into computers when my father brought a 33Mhz Cyrix. Since then have broken and fixed them. Kept interest in technology and software side for a while but never went into the field.

Decided to do construction, then HVAC tech and electrician and love it, but have not stopped keeping up with electronics.

At about the time my brother went to college for computer science, I started to read up on his electronics books and self taught circuit/schematic layout understanding. Have always repaired simple repairs and...
