    Q5wvh la-7912p

    Hi!

    There is no voltage on PC255 / PC256 Cpu power. Anything else seems to be ok. Nothing short, nothing hot, try start, 4 times. No display. Cpu replaced no change.

    Any idea? Bios possible?

    Thx

              Check Dram reset signal on PIN30 of ram slot. Should be 1.5v. Check its present or not but first as peirnov has suggested flash bios.

                          Acer E1-571G Q5WVH LA-7912P Rev 1.0 Bypass Touchpad Requirement
                          by uintptr
                          Hello, i have Q5WVH LA-7912P Rev 1.0 motherboard on my old PC. I accidently broke the touchpad things when replacing the back and up case. After doing that my motherboard going to blinking orange light on LED2. When I properly seat that touchpad thing, it occasionally boots. I think the problem is because of this. I don't have a soldering iron, so I can't solder it there. Since I'm going to use the computer as a server, I don't need a touchpad. I'm also leaving a photo for better understanding. I need to short-circuit it and make it work all the time. Which pins is for short-circuit? Thank you....

                          Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
                          by ohren
                          I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

                          I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

                          The models launched in 2018 and 2019 respectively....

                          by evilkitty
                          I have 2 access points, one a U6-LR and WZR-300HP running DD-WRT v3.0-r28444 (has had stable wifi since 2015)

                          and i am trying to work on my PICO W and it suddenly would not connect and my computer had a very hard time connecting and my dad had been complained about his phone connecting

                          so i ran a wifi scan script on the pico and it just hang for several seconds and found nothing, normally it would spit out every AP in under a second (both of mine and some neighbors)

                          What i did was just install a U6-Lite that i had not gotten around to installing to replace...

                          My wife is asking me about getting one because our electric bill was that it has ever been even more than last year at this time nothing has really changed since last year last month unless the electric company has done some fuel adjustment charges I have not done any investigation into yet but I might have to but there was a time back a few years ago that I use to set the temperature warm during the day when we were not home but when we got wooden floors in our house and you have to keep the humidity down to keep it from warping I just set to a temperature to 75*F to keep the humidity down but...
