Ive seen this before and i believe it may have more depth than just strapping. In the past few weeks i put 005's on both samsung 1GB 084 boards and hynix ones too. All working good. Id be interested to know the brand of the VRAM installed and the actually capacity? (i imagine its 2.4/sam1gb)...

Hardware (well in OSX atleast) never easy to tell in boot menu. But as i say it disappears and re-appears whenever it feels like it and there is no liquid damage or corrosion. The diode mode readings from the wifi connector are very similar to a working board other than a couple pins that go...

Hey. Got an 820-3437 that came in with strange fault and almost no sign of liquid damage. Fan would only spin up once and it wouldn't post. I ran it through the ultrasonic cleaner- It came out working, but has a strange wifi issue. Sometimes it will have wifi at boot menue but not in OSX...

Yes, ALL_SYS_PWRGD comes high if R8164 is removed. Fan spins up twice, V-Core present.ect No post

I am slightly cheaper than I should be but I believe my pricing is fair, and I would lose a lot of my trade customers if I were to change my pricing structure. It can be argued that a lower price can mean a higher quantity, If you are good/efficient and have the right staff in place at a viable...

ahh, sorry i was unclear, it dropped back to 0.95. al other rails there but v-core.

It is not low resistance to GND. I have had ALL_SYS_PWRGD come up a couple times after messing around (and even got 1v05 up at some point temporarily) but it seems to be related to the heat of replacing random components. When 1v05 came up so did ALL_SYS_PWRGD, but it never actually posted. The...

I have a 3435 board here im working on thats got me stumped. It is missing ALL_SYS_PWRGD, All power rails required for ALL_SYS_PWRGD are present However PP1v05_S0 is lower than it should be. it is only making 0.95V for some reason. I have replaced the feedback resistors and the IC. checked all...

0.3mm, All the stencils i have are rubbish so i have to do Gmux's by hand with solder balls :(

Got some more unanswerable questions for you guys. I have an 820-3662 I picked up about 18 months ago and refurbished it had minor liquid damage. I replaced the LCD side screen connector and cable, gave the board an ultrasonic clean and it was good to go. there was minimal corrosion but there...

good thought on the RAM, wonder if when these have bad ram they beep like the others, im yet to have seen it. The LED should be bad as when i check it with diode mode it lights up correctly.

just spend ages picking of the edge bonding and ensure theres none under the chip, then a reflow will do the trick, Much easier than reballing.

820-00045 here that apparently was freezing then went no post it has no liquid damage, it seems to have all power rails. But one thing throwing me off is that the SYS_DETECT LED is not lighting up, despite getting the correct power to it. Anyone get any ideas?

i bought a 820-3330 for stupid money of aliexpress for a desperate customer once. It wouldn't boot fully, it was missing some small passive components, and it had its bios reflashed. This was a few years ago back in the day before knowing ME regions were of importance. To cut a long story short...

To answer the question in hand, No its not necessary, it can be useful. I have had a shuttlesttar sp360c, and am now running a BIRD8888 with the hot air top heater. Get a good inspection camera and sidfe mount it to view the balls. when a BGA site is cleaned correctly it should be easy to tell...

Yeah it detects something, Ive replaced the LVDS connector on the odd chance it fixed it (like one other odd one recently), But no dice, the cables are undamaged, and as stated ive tried other assemblies with clean cables. In system preferences it only see's the external display. Ive tried...

There is no image on the screen. confirmed in OSX system preferences, this is the original display. There is no keyboard backlight either, but the keyboard keys react as if the keyboard backlight is present. But i have tried 4 or 5 different screens, some i know are from 13/14 so should...

Holly Shit my power button functions after replacing those fets. The fets i put on get pretty hot now so im not sure if they are safe to leave on there. Do They naturally run hot? gobsmaked that replacing those fets restored my power button though, Good work!

My 820-3332 has 12.1V instead of 12.6V. The only noticeable thing that doesn't function properly is the power button. if pressed when the laptops on, it instantly restarts. When off it doesn't turn the machine on, you have to unplug the battery, plug in a charger and then hotplug the battery...

As titled, 3787 with a known good screen . Backlight enable is not present. VIN is present, Fuse is good, Power goes no further than Q7706 as normal when its not enabling. No shorts.ect Works on external. Kinda at a loss as there is no sign of liquid anywhere on the machine so i dont know where...
