I use a blendtec... I use it for smoothies and for shakes (healthy, but taste great!)
I started out with a Ninja and it was great for what it was (and great price), as starter blender, but it left a lot of the smoothies rather chunky. Some people love pulp and chunks... I'm not a fan.
The ninja...
I fourth the WineBottler program! Use it on my 27" iMac and send it over to my second 32" monitor (not 4k, but it works for me ;) ) and have the schematic open on my main screen. Works great!
If it were me, I would just look on ebay and purchase one off of there (BIOSDEPOT is the user I got mine from, a few months ago.) I had a 2009 2.53 with similar stripped down issues. I replaced the SPI ROM with one from ebay, that was already "programmed" and was good to go. If it is a 2009, if...
I had the U5755 shorted on a 820-2915 board the other day. Always interesting to start noticing common points of weakness. (Glad that failed than something more important)
I have a similar issue to someone with the 820-3115, I believe.
820-2915 board. Keeps booting in Safe mode. But I figured it was due to liquid damage on the keyboard. I could hold down shift when booting and it would do a normal boot and not go into safe mode. Figured the keyboard was screwed...
So I removed the BCM chip... no more hot spots on the board.
BUT... when I was going through all the rails to make sure they were present, the PP15V_T29 is "missing"
Schematic says, duh, Vout = 15V... I am only getting 0.485V on C3897... Is T29 the thunderbolt circuitry? I plugged in a...
Okay, just wanted to make sure it wouldn't screw up anything else. Coming off then!!
I do have one from a "hole" donor board, I may try to put on... We'll see
Thanks!
So, this is the same 2011 15" computer. Have it running "fine" however, after I was about to run tests on the board, I touched the Broadcom BCM57765B0 chip and it is boiling hot. Actually at first, I touched the other side of the board, behind the BCM chip and couldn't figure out why some...
U5755 Was shorted to ground. I knew the general area of the short as there were a few components getting warm. I started removing the caps first, in hopes it would be "easier" but then started with u5750 and still had the short and then u5755 was the culprit!! Replaced both u5750 and u5755 and...
I have a 2011 15" 820-2915 board. I don't have a green light on charger (computer is completely dead. Using a known working OEM 85W charger.
I checked PPBUS_G3H and I get 0.642V... I then check PP3V42_g3h and I get 0.000V.
PPBUS_G3H is not shorted to ground 0.437 diode measurement.
PP3V42_G3H...
I just wanted to write my first post as a sincere thank you to Louis for all his videos (past and future) and for the idea of this forum (He could have said F-it, I'm not answering questions in ANY format any longer!!)
This should be a good time!
