Friend has a two-year-old Acer Aspire 5315 which seems to have turned into a brick.

Battery (I think is flat) but having removed it there is no power light or other sign of life when I turn on from AC Adaptor. Adaptor itself is OK, checked voltage - also tried another adaptor.

RAM and HDD are OK. Took out and checked.

Any ideas please?

Do you get any lights with both the battery and power supply on?

There are two things I think it could be (which I have seen in the past):

1. The CMOS battery could need replacing - this would mean opening up the laptop, etc.

2. The socket on the laptop where you plug in the charger could be damaged.  Unfortunately if this is the case, the likelihood of getting that fixed is minimal, as you would need to replace the entire mainboard.

Good luck!

Check the DC jack and the wire connecting to from the adaptor.
Remove the battery out and only using the AC.

Also check the RAM module. if you have two RAM module  use one at a time.
A faulty RAM could cause a problem.

I still think its either a dead CMOS battery or faulty mainboard.

Remove the CDROM, HD, RAM  and other accessories.

With the RAM removed do you get any beeps from the laptop.
If you get no beeps it would confirm that the mother
mother board is screwed up..

Open up the laptop and have a look inside to check the
capacitor in the power module.
Also see if all the connections are okie.

Worst scenario you will need to replace the mother board.
