Vaio DA0HK1MB6E0 MBX-247 Burning any EC
Hello to all.
I have this Sony Vaio QUANTA HK1 DA0HK1MB6E0 MBX-247 that is burning the NUVOTON EC when you connect it to power supply.
1) The +3vpcu line is going to a direct short after connecting the motherboard to power supply.
2) I discovered the EC NUVOTON was shorted. After removing it the short gone out on that line (+3vpcu) but... (If i quit the EC the 3.3v are pressent on +3vpcu because the shorted component was quited)
3) There were no shorts after soldering the new EC NUVOTON. But after connecting the board to power supply the EC keeps burning... -

Re: Asus X541UVK Rev 2.0: random freezes, black screen, no boot
Hi! I finally got the motherboard working perfect at the moment. I have done another manually clean ME attemp using another ME version and now seems that it is working OK. Even the HDMI works when it was not working.
One weird thing in this board is that there are no BGA rams (only the pads are present but not the RAM sticks) and it is stock and rev. 2.0. I used the same boardview @Spider1211 but the side of my board is different that's the weird fact. Even the chipset that it is present in the attached...Last edited by SMDFlea; 06-07-2021, 01:52 PM.Leave a comment:

Re: Asus X541UVK Rev 2.0: random freezes, black screen, no boot
Hello! Sorry for delay in reply
1- I reflashed BIOS with mon2 shared bin, boot fine but cant install S.O. It gives errror when i try to format it or create new partitions. I did a clean ME and still the same.
2- I cleaned the ME Region in my original dump and it does the same. It boots but you cant install SO or boot the hdd/ssd drive (even if Windows is installed on that drive)
3- Can you please post a pic of that R5852 @Spider1211? Because i have been searching for it with a boardview but...Last edited by ignacio.ino27; 06-04-2021, 06:03 PM.Leave a comment:

Asus X541UVK Rev 2.0: random freezes, black screen, no boot
Hi to all. I have a Asus laptop X541UVK Rev 2.0 that sometimes gives no video, sometimes will shutdown randomly, sometimes goes to black screen after being working fine at random times.
I say "sometimes" because it was working fine for 24hs, then it starts to do the same weird stuff.
I did thermal paste replaced (it was FULL of dirty inside the heatsink and cooler), RAM checked and it's OK, HDD replaced and the same.
Last time i run a stress test for 15min and the temp did not exceed 49 celsius. It is a Intel i3 7t generation. RAM tests gives...Last edited by ignacio.ino27; 05-20-2021, 12:58 PM. -

Re: Sony Vaio shorted caps on radeon 216-0752001
My doubt is about the ohm value of the pair of caps. They show me 0.001 ohm, is that indicative of failure chip? (And the high temperature it gets and the high (1 Amp) consume of the board without giving signal to displayLeave a comment:

Sony Vaio shorted caps on radeon 216-0752001
Hi to all! I have a sony vaio vpcee23el with no video. The chipset (radeon 216-0752001) gets very hot at few seconds after powering on the notebook. I have found two caps on the chipset that shows 0.001 ohm. Is that indicative of a faulty chipset? Thanks very much!
The caps on red show 0.001 ohm on multimeter.
Board takes like 0.9 -1 A after powering on (no video).
No activity results to display
