Sorry that was a typo. Is there anything else I can check?. Is it possible to replace the nand ?. I dont have donor for this board, possible to buy new nand?. also which ic number do you suspect?.

I replaced U9300 again and also U9400 now getting SSD voltages. L9320 p0v9_reg_sw = .9v L9321 P0v9_reg_swl = .9v L9300 p0v9_fixed_SWl = .9v C9356 pp1v2_sd_cold = 1.2v L9330 p1v2_hot_sw = 1.2v C9335 p1v2_ssd_hot = 1.2v L9340 p1v8_cold_sw0 = 1.8v L9341 p1v8_cold_sw1 = 1.8v storage_lb_en = 3.3v...

I replaced U9300 now PP1V2_SSD_HOT short is gone but only ssd voltages I get is pp3v3_s5_ssd 3.3v. STORAGE_LB_EN: 3.3V SSD_RESET_LB_L: 3.3V LPSR_EN_LB_L: 3.3V SSD_BOOT_LB_L: 1.7V

Thanks for your input I have ordered a new battery and will work from there.

As this had water damage as previous mentioned I wanted to make sure board was reading ok before buying a battery as they are expensive and I dont see many 11" mac air's.

PPBUS_G3H is 8.59v without battery r6950 is fine at 10k Scl/Sda lines are 0.445v diode mode and 3.3v on both I dont have another battery to verify if battery is bad.

I had a bit of spillage on the board but nothing around smc or charging Ic. What diode reading should I be getting around C7117 (PPVBAT_G3H_CHGR_R) Im getting 0.113v on diode. Im getting 8.6v on Q7155 pin 5

Thank you. I will try that out.

No liquid spills. 1 is very slow to post logo and slow loading. Second one is black screen. these should be shareable links.

I have 2 A1707 1 with board number 820-00928-a and 1 with 820-00928-04 Im looking for clean bios for both but have no luck with search function on the forum.

Seems PP1V2_SSD_HOT line is short and when I inject 1.2v into L9330 u9300 gets hot. I guess I will start with this ic.

Yes

No it doesnt detect ssd any way I try. no sign of spillage.

Might be. I found a pic of the mobo on ebay and the model is on the underside. Is there a know issue with the ssd on this model?

I have a 2016 13" macbook pro touchbar model thats does not see the internal ssd.

Ok will try that. Thanks for your time.

Yea all are ok and 5v present

Apologies I mistyped 820-3437
