Hi. No fan spin whatsoever. Present rails. PPBUS PP3V42 PP5VIN_S5_HS_Computing PPVIN_S5_HS_GPU PPVIN_S5_HS_Other PPDCIN PPRTC G3H PP5V_S5 PP3V3_S5 pm_slp_s4_l Diode mode .480V Liquid damage heavy around U9600, J2550 area, T29 Area and Codec Area. Replaced burnt corroded components around...

Hi. No liquid damage. Looks like SMC was replaced. Original the fan would spin once for 3 seconds but not recently. All power rails are present up to PP5V_S3. Diode mode 0.412. Have 12.6V on 23 of U7201. SMC_PM_G2_EN is 3.4.V. Missing PM_SLP_S4_L. Diode on this line is .480. Thanks for your help.

Hi. When I started this board I had PP3v42 but with no green light and no PPBUS. PP3v42 was 3.42V and PPBUS was shorted to ground.ISL was getting hot so I removed it and replaced ISL. I checked PPBUS in diode and most of the short was almost gone (0.386) but still no PPBUS. I plugged in the...

Hey. Have this board with liquid damge missing PP3V42. Obvious damage was under the heatsink bar leading to the fins which I replaced as well as U5010. I now have PP3V42 with a green light but only for a minute with 1 fan spin. In diode mode I get 0.088 but this seems to be getting pulled to...

U1900 gets warm. Replaced it with new and replacement gets warm as well. G3H is 8.6V, PP3v42 is 3.37V, PPVRTC_G3H 0.157. pn 1 - 0.157 pn 2 - 3.307V pn 5 - 3.291V pn 6 - 0 pn 13 3.370V pn 14 - 0.7 Diode mode pn 1 - 0.01 pn 2 - .046 pn 5 - .049 pn 6 - .317 pn 13 - .296 pn 14 - .386 Thanks...

Hi. I have a 820-3437 with no Trackpad/Keyboard in Operating System except for power button. Both keyboard and trackpad will work pre - O.S. External KB/Mouse will work fine. Have tried with multiple Operating Systems. Thank you. Have a good one.

Not sure where to start here. U6630 ?

Hi. This board had a short on PPBUS from Q7530. I have replaced it and computer now turns on but with this little problem. https://goo.gl/photos/Zqmf2aU3hzkwQ3C7A Thanks. Have a good one.

Hi. Board has an Image but no Backlight. This board started as an lcd connector replacement to regain backlight because when old connector was tapped the backlight would go in and out. Tried known good working LCD. So I changed the connector and it seemed to work fine for a bit. Then backlight...

Tried known working display assemblies. Is this GPU or ??? Thank you. https://photos.app.goo.gl/Ou7kBYFEadwOaW3v1

Hi. I have this machine that a shop technician forced the LCD cable in crooked and broke a piece off in the LCD connector. I have change the LCD connector and tried with known working LCD/cable with the same result. Sorry for not leaving any measurements. I had to leave early and wanted to ask...

Hi. I have an A1278 that after 30 seconds the screen scrambles. At first, my thought was that it was going to be an LCD/cable replacement. I removed the board to look it it over and found that U2600 and the area around it was liquid damaged. I have already replaced the damaged components and...

I have a 2012 A1278 that Very intermittently will have flickering lines across the screen and sometimes may freeze. Customer says that it happens very quickly and randomly. I myself however didn't experience it until I tilted it backwards from under trackpad. I thought it could be an LCD cable...

G3H Starts at 1.9V and drains slowly to 0 PP3v42 - 3.41 G3H Resistance in Diode mode - 0.440 Board looks like it has been worked on before. Flux around U9600 and U7201. Thanks in advance.

Hello. got this in for not charging battery. It sees it and shows its connected but light on charger never turns amber and system report states that it is not charging. If I unplug machine will still run. upon checking the board i noticed the around the BIL connector there was liquid damage. Pin...

2010 A1286 came in today for overheating/shutting down issues. Everything worked fine (Booted into OS full video and backlight, chime.) except for the overheating when it was dropped off in queue. A couple hours later when I turned it on it would only boot video but no backlight. At this time...

Hello. I have 820-2915 with no wifi (no hardware). I have already tested with known working card. Here are pin measurements from connector. L3404 is working and has been replaced just in case. Thank you. Have a good one. pn 22 - 3.3V pn 24 - 3.3V pn 26 - 3.3V pn 27 - 3.3V pn 28 - 3.3V pn 29...

G3H - 12.5 PPBUS_S5_HS_COMP - 12.5 PPDCIN - 16.8 PP3V42- 3.3 PPVRTC - 3.3 PP5V_S5- 5 PP5V_SUS- 5 PP5V_S3 - Missiing Checked thoroughly. No sign of any type of damage. Thank you in advance. Have a good one.

Hi. I have a 820-2936 with no backlight with 12.5 volts on pins 21 & 22 of J9000. After changing LP8550 I still have 12.5 volts on output. Thanks for any help in advance.

Hi. So, I have a board here that came in with no backlight, but had full video. I replaced C9020 and C9796 because they looked burnt. Also L9080 was missing completely so I replaced that as well. Turned the laptop on to see if it made a difference and I got a chime with a quick flash from the...
