Hello my friend, thank you I’m so grateful for this video.. it’s such an eye-opener, you shed light on a lot of things, wish I had your knowledge., I’ve watched the video twice, I’m going to watch it again tomorrow to make some notes on key components (resistor, mosfets) and expected voltages that you mentioned, the expected delivery date for the donor board is 25 JULY! so in the meantime I might practice checking for shorts, removing the burned chip and check again for shorts and take some before and after measurements I have partially assembled the laptop to test the system with a SSD and installing windows, all works well running off battery, I tried to update the bios using dell utility (to see if it fixes the delayed bootup issue) but the bios software is saying I need charger and battery both connected first If the charging chip is fried then how is the system still detecting there is no charger and/or battery connected, the battery charge percentage is also shown accurately in windows task bar Is it possible for chip to be fried and still function normally? Thinking logically if the resistor you mentioned is short then it’s letting 19v straight into the chip and frying it (that’s why it fries every time I connect the charger), I’ll keep you updated, thanks again
NP. Sorry for my English. I am not very confident on camera LOL. Try to remove chip and measure mos-fets and resistor. There are two more things running of 19 Volts but I believe you will not have smoke without chip however use current limited bench PSU or 12 Volts adapter with 12V car bulbs in series.
Hello Marcel, I have the same laptop and the exact same issue, so thank you for giving me a place to start! Is it possible to order these chips new online if I do not have a second laptop for spares? Kind regards, Jason
Hi, where are you from? I have always used compatible parts from donor board and scrapyard as it was way faster ;) to finish. Big mess on the table so can't wait :D as always busy thanks to children :)
