Re: HP Spectre 13 x360 - ae000nu DA0X33MBAF0 REV.F No Power

I found this from the quanta X31 schematics. Mine is quanta X33 for which the schematics is not available yet. On pin number 9 I see the same configuration: 2R2 with cap. Pin 10 also match but some of the others don't. Anyway I made some measurements with removed PR229 on both sides of it.
I think definitely the 1740VCC is short to ground and considering the thermal imaging it is the 5833 chip, not the cap PC239. But isn't the 5VS5 line resistance too low. Where is this voltage generated from? Isn't it used on the...

It is just below the coil and on the right of the metal plate covering the ram. I am suspecting it of short to ground as it gets hot together with the 2.2res on the bottom left corner/considering the image from previous comment/ when injecting voltage to PP_HV lines on TPS65988. Also the battery connector is visible at the bottom right....

Does anybody know what is this IC so I can find it's data sheet....

Re: HP Spectre X360 I need da0x33mbaf0 rev f schematic

Did you find any schematics? I need them as well.

Hi declassified-pro,

Thanks for the fast reply. I attached few photos from the motherboard. I think the size have been reduced once imported so let me know if you need higher resolution ones or you need specific details. Meanwhile I will check if I can find anything suspicious....

Hello,

I have the laptop mentioned in the title which does not power on. Unfortunately schematics are not available or at least I was not able to find any.
First I started with measurements of all MosFETS, filters/coils and random capacitors. I managed identified shorted caps nearby the IC TPS65988CE. It was on PP_HV1, PP_HV2 and more lines nearby so after thermal camera observation I saw that the actual IC was getting hot when plugged into 5V DC. It was draining ~360mA. Though if I plug the original adapter it was not getting hot but input voltage was dropping to 0V. I...
