I have recently acquired my Dell Inspiron 15 7000, and I am interested in building an egpu setup for it. It has a USB-C port. Any recommendations/guides out there?
I reversed the input polarity on my m15x jack after a botched psu repair. Computer worked fine, but overall power control is messed up. System only boot on both battery and psu, no battery charge, and a very low battery drain (arround 6wh).
I aways had battery issues whith my 8 years old m15x after my original battery died. Bought a new one two years ago, didn't work. Checked on upower, basically no info on manufacturer, power or history. So i refunded and used the system hooked on the psu as usual. In August i bought a new one, worked flawlessly for a day. The next day the battery died from nowere. Checked upower, bus was ok, battery was charging extremely slowly (6wh), history showed subpar disharge before shutting down. I got mad at this point, decided that psu was to blame. Opened it, checked everything, noticed some wear on the male jack. Resoldered it, connected on computer. Nothing happened, so i checked the voltage. That's when i realised that i screwed up big time. I swaped the positive and negative wires. Decided that one mistake was enough, so i sent my m15x to a trusted repair shop (latter found that they just hooked the battery and gave me back as soon as it booted, they didnt even open it). Got my pc a week later, but the battery didn't charge . Worse, it was slowly discharging (same 6wh as before), and it needed both the psu and the battery to turn on. At 65%, it worked as usual for my college semester, but the battery is dead, and so is my computer. I bellieve i burned some voltage controller or something. I'm pretty competent at soldering thing's (evem smd components) when i know what to do, and i can understand simple circuit's, but when i got my hands on the m15x datasheet i got overblown. I cant make heads or tails about it. I aways lurked this forum and i bellieve your guys are the best when it comes to finding creative solutions to technical problems concerning microelectronics. I followed a guide in this forum as a teenager to upgrade this same computer to a gtx680m, overclocked stuff, got custom bios, and had a lot of fun learning. The m15x is a deprecated platform, but it's a part of my history that i dont want to let go.
So please guys, help me.
In this thread you can post your requests for Lenovo ThinkPad T450s.
If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, or already upgraded Display and after that can't adjust screen brightness, then you can post your request in this thread.
For creating bios backup and to flash bios mod, you must use any SPI programmer (like CH341A programmer) and a SOIC8/SOP8 test clip!
Just dump your Bios using any SPI programmer (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.
SOIC8/SOP8 test clip:
How to use it:
Also, you can search on YouTube a lot of guide for CH341a.
Hey guys, I am Grga and i am new here. I rarely use forums but i am desperate in this case.
So, as i have seen many of you have had the issue with obsolete BIOS versions for clevo P7xxZM machines,
So i would like to hear your experiences and how you went about it.
I have recently bought an ssd Samsung 970 PRO NVMe M.2. From which i would like to boot the windows10.
Little did i know that there was no support for that kind of protocol in the BIOS or that there is such thing as UEFI (for which i am still not sure what that is exactly, except some kind of successor of BIOS).
So i did a bit of research and updated my Bios and ec to 1.03.15 and 1.03.09 respectively for which i understand is the last available official release. I changed to uefi mode with secure boot disabled etc... in short i did everything that my (limited) knowledge about these things allowed me to do (and the sweat of excitement and fear when i was flashing the bios for the first time in my life). But, alas, it all yielded no success, and now i am lost. I have really no idea what to do, and whom to ask for help except for you guys here. The only thing that i understand worked for some of you is when you mentioned a wizard named @Prema so therefore i will try to do the same....
