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.
Hi there guys,
I've been looking into getting a new GPU for my laptop (4-lane PCI-e) and enclosure (HP Omen Enclosure) but I cannot decided between the RX 5700 XT and the RTX 2070 (non SUPER).
I did some price to performance calculations (higher is better) with some of the best prices I can currently get in the UK.
The RX 5700 XT does perform better and is cheaper than the RTX 2070 (Although the 2070 does come with 2 games) but my main concern is drivers and from what I've heard NVIDIA cards work a lot better with eGPUs than AMD.
If anyone has experience using both red & green or if anyone else has any other input i'd love to hear your experiences and input.
Hey everyone! After lots of searching it looks like this is the go-to place for laptop mods online, so I figured this would be the best place to ask something like this.
I picked up a Dell E6530 for basically scrap value, and I love the thing. Runs Xubuntu great, battery is halfway decent, and I can play 99% of the games I own on it. My friend on the other hand picked up an E6440 with its silver-ish finish along the back. As much as I love my 6530 I've gotta say, that thing looks great.
To get to the point now, I was wondering if it's possible for me to polish the top of the lid on my 6530 to have a more silver finish like that (or maybe even a mirror finish if I sand it down with a fine enough grit). Really what I want to know is if the dark grey part of the lid is actually metal. I can't seem to get a definitive answer online, and I tried the magnet test on it and it wasn't magnetic at all. This doesn't necessarily mean it's not metal though, as aluminum isn't magnetic but is obviously a sandable/polishable metal. One source said the laptop has anodized aluminum parts on it, but they didn't specify whether it was something internal or external.
Can anyone here provide me some insight? If the grey part is definitely a metal and not a plastic, I think I'm gonna give it a try. As stated before I got this thing for scrap value, so if in the end it doesn't work out I'm not gonna cry over it or anything. Still though, I'd rather not run into this blind. If this is indeed possible though and I can accomplish what I want with a decent looking result, I'll post up some pictures with the method I used for others to do as well.
Thanks in advance!
Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:
- MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
- Razer X Core
- Apple TB3 to TB2 Adapter
- TB2 Cable (Cable Matters)
- 23inch AOC External Monitor
I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.
Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.
I have a Dell Inspiron 5555 with BIOS A12 and I am missing some options in the advance menu. The BIOS seems to be shared between the 5455 and the 5755, if it helps. Can anyone help me figure a way to have all the options in the BIOS available?
I have attached the results archive from the backup tool, if it helps
Thanks in advance!
