Hi all, I've got a clients Acer Aspire 7740 Laptop that wont boot, black screen, fan not spinning, nothing.
2 months ago I replaced his hard drive, re-installed Win 7 and supplied a new Delta charger. All was good.
At first I thought 'duff charger' but no, it tests fine 19.23v and works on another Acer.
Ok, duff HDD, no tests fine.
Must be the DC jack, no tests fine, I'm getting power to the battery connections, 3.33v on 3 pins.
Replaced RAM, removed WLAN and so on.
I've given the mobo a good eyeball inspection, it looks perfect.
And I'm now stuck, I've got the schematic but I'm pretty clueless at this stuff. I have replaced loads of DC jacks, USB ports and audio jacks but thats about my limit.
So, can any of you good guys be of assistance? If I can't get it going I will refund the guy for the charger & HDD, but I'd rather fix it for him.
Cheers in advance
Dave
