Jack plug /power supply issues in Gateway laptops : Is anyone aware of a generic fault, that causes laptops to quit after 12 months of use ?
I’ve got 2 that have died within weeks of each other, both with the same fault. (Model ML6227 b).
Now that Gateway have went belly up & been bought by ACER, they want nearly £160 per unit to fix it, even then they only give it 1 months warranty !
Bit rough for a laptop that was only bought last Xmas…

yeh im trying to remove the dc jack but theres so little solder on the pins i read one of your guids how to remover a dc jack is it says “Start desoldering process with adding some new fresh solder to all three contacts. This will make old solder more flowable, easier to remove” but its not working

Paul,
Apparently you haven’t cleaned them enough. Did you remove the power jack from the motherboard?
Here’s how I resolder the jack:
1. Unsolder the jack from the motherboard.
2. Clean pins on the jack with a knife and apply new coat of solder.
3. Clean terminals on the motherboard and apply new coat of solder.
4. Install the power jack back on the motherboard and solder it.
If you are trying to clean the pins while the jack is still installed on the motherboard, it’s not going to work.

[...] In this model the power connector is not attached to the motherboard directly, it’s located on a DC power board. You’ll have to remove the DC power board and resolder the power connector or replace the entire board. You can find a new DC power board if you search on the Internet for this part number DA0CT2PB6D8, but it’s kinda expensive. [...]
