Toshiba Satellite p15s420 problems

jvande02 · 06-28-2008, 10:50 AM

I have a Satellite p15s420 notebook,with a p4 ht processor. The laptop charges when turned off however will not charge while windows is running.
I tried removing the battery and turning on the laptop however laptop will not turn on,it does for a millisecond until lcd lits up and then shuts off.
I tried switching power packs with one that is the exact same output and hz and same result.
I tested voltage to battery bay and it appears normal while off however am unable to test without battery while turned on.
I am thinking the resolution may not be hardware related, I am wondering if it might be a control(bios issue or etc).. and the reasoning behind my theory is windows shows the laptop as being plugged in,but not charging and drains the battery while active.

What is your charger putting out? Most chargers will have 2 ratings on their sticker- one for trickle charge and one for "on" usage. my HP doesn't, but most will say something like 12.4VDC @ .83A for trickle and 13.8VDC @1.5A for "on".

My charger is rated at 19 v 3.95a exact same as old charger, To update my problem I have traced it back to software, I re installed windows xp the actual system not oem version and charger actually charged while turned on and then i installed toshiba drivers for xp and it stopped again so I am now undoing the toshiba drivers one by one to get further info on which software/hardware combo maybee at fault for my problem.I will update in further posts
