Macbook Pro a1502 touchpad and keyboard not working

i got a request to repair a macbook pro model a1502 the keyboard and trackpad stopped working on. i did some testing hoping it was the “press this key 5 times to enable keyboard” kind of issue… it wasnt but i did notice the keyboard would wake it up from a deep sleep, so i thought maybe it was a software issue, cleared the pram and did a reset, nothing. i then also noticed the key combo for a forced restart worked… i had read about the ribbon cable connecting the trackpad and keyboard to the motherboard goes bad on these often, but i assumed if that was the issue key combos and stuff wouldnt be working!? next step a factory reset after i backed it up. nothing.

i finally decided after all this troubleshooting to lookup the ribbon cable and see how much it was $10 prime on amazon, ok i will give it a try. sure enough that fixed it.

if you have this issue and decide to replace the ribbon be sure to have a P5 bit and a T5 bit to get the case open, the bottom cover uses the P5 and the cover over one end of the ribbon cable uses the T5. i just grabbed a kobalt electronics driver set at lowes and it had everything in it to get the job done, even prying tools that are handy for popping the ribbon cable out and lifting the lever to slide the other side out. thanks for reading and good luck!

moving a centos virtual machine in hyper-v and fixing network issues afterwards

i have been testing an NGINX cache i have setup for caching steam games and i have been testing download speeds having the cache on different types of disks so i could find what has the best performance, but every time ive moved it my network config gets messed up in centos 7.  ive had to figure out how to fix it 3 times now because i forgot how i did it, now i dont have the normal network configuration i have the network configuration tool disabled and manually set the nic settings in /etc/sysconfig/network-scripts/. when you delete the virtual machine and re-create it on another disk using the old disk image the new vm will generate a new MAC address for said machine which throws the manual config off because its looking for another networking device. heres the steps to fix this.

First open /etc/sysconfig/network-scripts/ in your favorite editor and look at the mac address. this will be usually in a vm “ifcfg-eth0” or whatever your adapter name is. simply open that file and look under “HWADDR=xx:xx:xx:xx:xx:xx:xx” that is the mac address your machine is going to be looking for to reconnect the nic.

now that we have the hardware address (MAC address) that we are looking for lets go into hyper-v settings for that VM and look at the options we have. first shut down the virtual machine, then right click the VM in hyper-v manager and click “settings” in the left panel click the  “+” sign next to “network adapter” go down to “advanced features” and in the right column you will see the “advanced features” options where it says “MAC address” change it from dynamic to static and check the box next to “enable MAC address spoofing”
then type the HWADDR under static.

Once you get that typed in there go ahead and click apply then power the virtual machine back up, it should fix the network configuration settings and it should boot normally with a working network config. To verify the network config is working correctly type in

sudo systemctl status network.service

if it succeeds and all is green you are ready to go, if not you might have something else wrong.

getting pi-hole to recognize individual clients behind a pfsense router

So, I installed pi-hole on a virtual machine at work, it worked great and a much better gui than pfblockerng/dnsbl but when I was looking at the list of clients the only thing showing was which is my pfsense router,  that is strange right? well the reason that is happening is because I just added the IP for pi-hole under system > general settings > DNS server settings which worked but the problem is the DHCP server was still telling the clients to look at pfsense’s DNS resolver instead of pi-hole so all the requests were going through DNS resolver thus showing only one client in pi-hole since all the requests were coming from it.

what fixed the issue was going to system > DHCP server scroll down to “server list” and add the IP address of pi-hole and your secondary (probably your pfsense address so the requests go to DNS resolver) DNS servers and hit apply and that will make all clients show up in pi-hole’s client list.

one last thing to note, this process will make all machines on the network bypass your DNS resolver so any custom URL redirects on there will not work anymore maybe I will work on a way around that in the future, but for now you might be better off using pfblockerng/dnsbl inside pfsense unless you know a workaround if you do please share! thanks for reading and I hope this helped.

EDIT: i found a way to redirect dns requests via pi-hole here

speed issue with private internet access in a hyper-v virtual machine

i was having an issue with stuff loading crazy slow in a hyper-v virtual machine after many searches online with people with the same issues and never an issue i kept looking and eventually i stumbled on this, its for “some versions of windows” which happens to fix the issues in a hyper-v vm. atleast it seems to be the case so far immediately after doing the driver install my speeds in utorrent were great and i could still access the internet where as if i had one torrent running it wouldnt even resolve a web address. hope this helps.

here’s the directions with source linked below, i will also mirror their download here incase their link is broken in the future.

Raid 5 expansion conundrum

On tuesday evening at about 6:45pm i started on the seemingly annual raid expansion, whenever i start to run out of data storage on my server i simply buy another 2tb hitahchi drive off of ebay throw it in and expand the array it works great everytime so far.
disclaimer: always do a backup before attempting any kind of storage changes you never know what may or maynot happen

lets jump back about 8 months ago i decided to take my 9650se-8lpml raid controller and swap it for the 9650se-12ml only difference being one supports 8 drives and one supports 12 drives so all i had to do was swap the controllers and plug my 4x 2tb hitachi drives into the new controller everything was recognized correctly i ran through the settings and made sure everything was good.

1990 starcraft starflyer DIY suspension lift

now that we are up to a family of 5 tent camping was starting to become a bunch of work with all the blow up mattresses bedding excetra having a nice tent trailer like this was an easy decision since you can keep bedding and everything inside and it takes about 10 minutes to deploy the whole thing and have it ready to sleep and or eat ontop of that there are 3 beds, one king size bed, one queen sized bed and a double that the dining table folds down into. plenty of sleeping space for the bunch of us.

to start with i went to the local steel supply shop and bought some 2×4 steel tubing enough to go the length of the girder on the axle on each side and a piece to connect the two sides then i brought them to my work where i have access to a band saw which made quick easy accurate cuts. i then threw them in the back of the car and headed home, hooked up the camper and drug it over to my dad’s house to get the fabrication done.

first thing i did was to jack the whole thing up off the ground and rest it on jackstands, then remove the 4 bolts holding the torsion axle to the frame and i had to hammer the axle till the rust finally broke loose and let it fall free. then came the fabrication all i did was clamp the two short pieces to the torsion axle’s support girders and then slid the cross piece in to place, i actually had to take it to a shop and cut another 1/8″ off because it was just barely too long to fit. after trimming and a bunch of hammering and measuring to make sure everything was lined up correctly i finally got it all welded together. while i had it clamped and laying on the ground i went ahead and marked my 4 holes that i would have to drill for the mounting bolts.
