Battery keeps discharging

Hi Guys
I have a problem with my p38 the battery keeps going flat and i don't know why (new battery fitted in dec as the old one did the same also new alternator fitted last week) but still keeps going flat.
Iv'e heard that the p38 can suffer from problems caused by laptop's and house alarms if this is so how do i get around the problem as next door has a house alarm and one on his garage and i use a laptop in doors.
The only good thing is it bump starts very easy and as i live up a mountain in portugal its not to bad but am planing a trip back to UK soon and would like to sort problem before i come back.
As usual any help would be Great.:doh:
Cheers for now.

This used to happen to my old rr apparently the signal is very similar to wireless broadband etc.

You could try disconnecting the rf receiver and see if that helps. If you do a search in the range rover section there should be instuctions on how to do it, an easy job to try and can be put back to normal if it doesnt help.

Not the same but similar in that two weeks standing and flat bat, that plus a lot of cranking on cold mornings.

Got a solar power trickle charger from maplin, on offer for £9 or so. Should be able to get one over there or order on-line.
