Hi guys , got here a problem with a recent machine that enter the lab ,
its a hp 15-e050sp the problem as charger port damaged , so we've ordered a new dc jack for it and we received we asked the client to bring us is powersupply since it is this new HP dc jack with bluetip with center pin but the smaller one, i didnt have this tip for my charger and client also was with center pin damaged , so we've bought a new charger for it , but not turning on and no dc jack led light turning on as well , usually this is bios or system charger . but would like to make some measures first before buying whatsoever i will need , but not finding this schematic to download at all , also was trying to chek pinnout for the BQ728 or also can be BQ24728 for i can know if all is ok with system charger before ordering one .
Also notice that i really dont have 3.3 or 5 volts on coils , but that i supose its a security measure to save energy and this will be only present when S5 is enabled . i got 3.3 on on off button and drop to 0 when pressed , and also got 3.3 volts on the bios as well , possible feeded by LDO of step controler . also got 5v LDO on the step controler (meanwhile dont know wich STEP controler is this and they are 2 right near each outher .
Now before ordering any part i would like to be more sure of what part buying , so if anyone have this board or schematic that can give me some pin values for the Charger ic i would be very greatful
meanwhile i leave here the values i got on the charger IC :
1- 19.8v
2- 19.8v
3- 19.8v
4- 24,9v
5- 2.8v
6- 2.5v
7- 0
8- 3.2v (between 3.1 and 3.2)
9- 3.2v (between 3.1 and 3.2)
10- 3.1v
11- 2.5v
12- 2.5v
13- 2.5v
14- 0v
15- 0v
16- 5.8v
17- 5.8v
18- 2.4v
19- 2.4v
20- 19.8volts
PS - also donwloaded bios from the hp site , inside of the exe file , there were 2 .bin files with same size just different dates , i saved the dump and tryed with both , still the same so i can see bios is not the problem .
Wait for some good news from you guys.
thk in advance
