Then one or more of the pieces are still bad. The cmos battery and such isn't much of a clue but after replacing all the hardware I'm sure you're too invested in this one to give up.
There are 3 basic parts such as motherboard battery and charger and we can do without the big battery so I'd get the folk that supplied your new mainboard to get you another one.
hey guys i have an emachines e520 laptop with 2gb ram and 250 gb hdd.
my problem is that the laptop will cut off after about 5 seconds.i have tested for overheating and replaced all the hardware.
i was told to replace the cmos battery which i did and found that it would then work for about 30 mins with the ram and hard drive removed.
what is the problem with this laptop?
i was then told that i would need to update my bios to stop these cut outs, but how can i do that when it keeps turning off?
Please help i need this laptop for school.
