Re: Compaq CQ62 power problem

Ok. I will measure all voltages later and post it here.


Hahaa, a dje si ti Djosla!!!

Re: Compaq CQ62 power problem

With only battery it is not making clicking sound, and can be used normally. Also it is charging batery. in windows for long time it is saying that is not charging becouse battery is bad, but orange LED is on next to AC plug. One more thing, PC must not be on to make that clicking sound, so it must be something in charging circuit gone bad.

PC works ok with battery, but board is doing same thing "pluging" in and out AC adaptor. When I plug battery in one capacitor is making noise and voltage on PCE20 is varying between 19.18V...

Re: Compaq CQ62 power problem

Anyone have idea what could cause problem?

Re: Compaq CQ62 power problem

Also AC_OFF signal is 0V in working mode, and when component starts making noise it changes between 0-3V.

Laptop model is CQ62-a20sm with AMD Athlon II P320 processor. Foxconn Motherboard, P/N: 01013TM00-575-G

I think schematics @JaroTech posted are right for this board?

Hi guys,
have problems with compaq cq62. Laptop sometimes starts, works fine for some time and start switching between AC and battery. AC adaptor is ok, checked voltages, so are adaptor connector going on motherboard. When working normally all voltages readings are fine (checked only few components following DCIN).

After some time LED signal (ACLED on image 1 in attachments) on connector stops shining and I hear component on motherboard clicking, as it appears to me it is coming from inductor PL7 (1R0). Also voltages which are in normal mode stable start to changle in clicking...

These are 90 mm. Thank you!...

Re: reballing problems

Hello evreryone!

Is it possible to directly heat stencyls made by Jovy Systems? I have black jig with set of universal stencyls.

Also have problems with balls joining together, becouse of universal stencyl.
