Hi All, sorry for my bad english
Just arrived Acer Aspire 4740G (COMPAL NALGO LA-5681P) at my Desk, power on just for 10sec and then go off, no display and no power for hdd dan DVD (3VS and 5VS is 0V)
First, I replaced the EC, but the problem still the same,
Second, I replaced HM55 and flash EC bios,
Now can boot but only for 30 sec and then go off (suspect ME Region Problem) and only can boot with Kingston Ram Module, and no worked with the other. I've tested 10 ram module, and only work with Kingston, and then I searched another bios, and got it from Acer's Website, and ME Region Problem solved. But the RAM problem still the same, only work with Kingston Ram Module. Machine work normally if i boot with mini xp on hiren boot CD, but cannot enter windows, after "starting windows" appears, the machine got restarted.
When I run memtest 86+, shows thousand errors (with kingston). but if i test the kingston ram module into the other laptop machine, it passed the memtest
I have tested it with another processor, clean the ram and cpu sockets, reflow the cpu socket, but still the same, only work with kingston but thousand errors on memtest86+ and cannot enter windows
What is suspect? Is it cpu socket problem? and I have to reball or replace the cpu socket??
Please give me a suggestion, thanks before...
