Pdp117p not working


The Power Supply is to be replaced if it is bad.

If you see no lights, hear no fan, no hard drive spinning then your power supply might be bad.

What is the center pin used for on the HP 3710b business notebook?I am using a IGO aftermarket power adapter that has the three pin connector tip with center pin like the one DELL uses.Checked with volt...


so what is the full service tag data?
3710b or 6710b, you posted both , and is not complete at all those numbers, (vast submodels exist)
the former number dont fly..

if the PC run ok, on AC pack (HP spec, pack) no battery installed then it (pack) and the PC are ok (no bad jacks)

leaving 2 things, battery (that love to fail) or the charging chip you can not unsolder, ever and replace.

the center pin, seen on the schematic
https://elektrotanya.com/hp_compaq_6510b_6710b_inventec_dd1.0_dosxx_dunkel_1.0_rev_a02_sch.pdf/download.html


or is the AC line loss early warning. (tells PC to go to battery early)
this signal ends up on the charge chip
called Charge Control line.

the schematic is free.
have no battery pack schematic that drives this pin
but its tells the PC to go to (battery early, as power fails AC)
the changer over is not instant
so they this pin tells the PC early, the power is failing
my guess, it can detect power loss, in the pack, in 2 milliseconds flat. (power loss early warning)

No picture and thumping sound


I just had the same problem with my TV and looking on the web I found a site that helped. The site was www.freelists.org/archives/techassist/11-24/msg00326.html The entry said Raster NO GO / Pulsing sound from speakers / Poss ant relay clicks in time to the pulsing. It recommended replacing C816 and C5a28 (100uf /200v Caps) C5a03 (4.7uf / 200v cap) My set did not have the ant relay clicks and I could not fine the C816 cap on the circuit board and I didn't have the schematic. I found the C5a28 and C5a03 caps about the middle of the circuit board in the same circuit (around the metal L shaped bracket). The C5a28 cap was bad and the C5a03 cap was fine. I replaced the C5a28 cap and the set works fine now.
