PB Battery problem

Message #1 - Posted 2005/05/01 - Stuart Hutchinson

How can I tell if there is a problem with my PB battery?

Today the PB went sick after 3 years faithful service. The battery is completely drained and refuses to charge even though the orange light shows that it is. The PB refuses to wake from it's sleep.

Curiously, if I connect it to a monitor and keyboard, it will work fine but the display won't work on it's own.

I've done a quick google search and it suggests a possible logic board failure and or battery.

Luckily my replacement Mac Mini turned up this week so I've transferred everything over so I won't lose any files.

Any advice would be gratefully recieved.

What happens if you power try powering it up with the battery removed? Does the screen work then? Just takes the battery out the fault equation then....

I think I've eliminated the battery as the problem. I now think it's a faulty connection between the screen and the computer. It works fine a flat surface but as soon as you apply some pressure to the case, the screen goes blank.

The machine took a fall a couple of months ago which dented the corner of the case but is has functioned fine since. On Sunday the problem started.

Whatever it is, it doesn't sound good nor cheap!

OK see if you can make it flick on and off as you tilt the screen, also see if it is just the backlight going or the vga, it may be easier with the monitor in mirror mode. There are two leads from the motherboard to the screen, one sends the vga signal, the other the power for the backlight, if you look v v closely when you tilt the screen, then you should

a) be able to see the desktop faintly in the background (backlight cable gone) £40 and a bugger to fit
b) the screen goes blank but the backlight stays on which you should be able to tell by the apple. In that case it is the logic board or the vga cable, the vga cables about £40 but a bugger to fit, logic board is crying money, in which case I'd start enquiring about your cover on your home contents as it's been caused by it being dropped [1]. I've currently got an iBook on the desk in loads of bits just need to get round to ordering the vga lead for it after replacing the backlight cable first [2] which didn't fix it for obvious reasons.

[1] See why I hammer on more bought accidental damage cover than extended warranty ;)
[2] I already had one on the desk

I agree re accdental damage cover. The computer is insured on a separate extension policy to my hosehold cover to allow me to take it abroad etc.

The machine is being collected this week for the insurers to asses the damage so hopefully all will be well.

Thanks for your excellent help Jon.

Much appreciated.
