Apple :: Can't Use The Second USB Port On My MBP When I Have A USB Hub Connected
Feb 25, 2009
I have my mouse hooked up to a USB port on my MBP, the other USB port is connected to a USB hub with a printer and a keyboard. Whenever I put my MBP in sleep, whenever I come out of sleep my mouse needs to be reconnected, but my keyboard and printer work fine. I never experienced this with my mouse before I got a Targus USB hub.
Just started using brand new Latitude E7240 and connected to E-port docking station. When booting an error pops up as below: The battery currently attached to the system will not supply enough power to dock for it to function. Please attach AC power to the dock for it to function normally
F1 - continue
F2- change setup options
The Laptop and the dock stations are brand new. This is only happening with the 7240's.
I have an SXPS 1340 running Windows 7 Ultimate. I have tried to connect a Western Digital My Book Home external HD through the esata port but i can't get the computer to recognise it. Has anyone else successfully connected this model HD to the 1340 through esata? To those of you who have successfully connected a different external HD through the esata port what brand and model of external HD are you using?
I bought this computer which is running 7win64 to update my T60 which I use with my home TV, a samsung digital running at 1360x768 resolution. The computer's native resolution is 1920x1080. I bought an hdmi adapter for the displayport from lenovo when I ordered the computer. Initially, the display works and at first it ran long enough to get everything set for a nice crisp display that fits the screen perfectly. The sound is there too, and is passed on to my receiver by the TV. Very nice. But then it begins to blink off until it doesn't work at all (the sound is cut off too). Lately it won't stay on long enough to review settings.
All updates are in place, both from microsoft and from lenovo. This has Intel 4600 graphics built in, and intel has graphics drivers available, but won't install them because of the lenovo supplied drivers.
I can't get any support from lenovo support because another device is involved.
I read online of some early users who had this problem with a docking station and i guess the problem was resolved with an updated driver.
I'm experiencing very strange problem with my Dell Vostro 3750. This machine is equipped with USB 2.0 capable USB ports and USB 3.0 capable ports. During the power-up any USB devices (or even multiple devices via hub) can be connected to the USB 2.0 capable port. However if even a single device is connected to one of the USB 3.0 capable ports, the system doesn't start.
I've reported the problem on the Linux kernel related lists: 59561
But the only answer was, that I should report it to Dell suggesting fixing of BIOS. Maybe this is a BIOS related problem, but Windows 7 starts on the same hardware configuration without problems.
As I'm mainly using Linux for my work, two USB ports are practically useless for me, I have to connect all my USB stuff via hubs to USB 2.0 ports.
My current BIOS (after last BIOS upgrade) is: DMI: Dell Inc. Dell System Vostro 3750/0VP036, BIOS A12 02/22/2012
When I connect my external monitor (ASUS PA248) to my W520, the audio disappears. When I disconnect it, the audio returns. This seems a bizarre link between audio and video, but there it is. Note that the PA248 does NOT have built-in speakers.
I just got a new macbook pro last monday and one of the usb ports doesnt work... I bought it at an apple store about 45 minutes from where I live... and I have set up an appointment with the genius bar (this is the only option they gave me). Do you think they will just replace it and give me another one (new)? I am a CS student taking summer classes and it is required for me to have a laptop. The laptop is only 10 days old... and I still have all of the original cd's, case, etc...
I bought a miniDisplay Port to HDMI and 3 HDMI Cables and a HDMI splitter from seller mambate on eBay. Surprisingly it was all really good quality, the audio works well, I wish I had a surround sound system to test it on but I use optical audio for HT. So my Hanns G 28 Monitor is really the only thing I could test it on, and it works.
The Splitter comes wit a remote too which I thought was cool.
This is my MBP13 and he Hanns G
Funny side note, the MBP quicktime plays better 1080p vids on the HannsG dont know why. either way plex is the best program for videos.
I have a 13.3" MBP and a HP LP3065 monitor. At times, I would like to use the monitor for more real estate. I know there is the Apple mini display port to dual-link dvi adapter. Are there any other options that I will be able to use my monitor at 2560x1600 resolution with the MBP?
The reviews for the apple adapter suck and basically all of them have flickering issues. I would hate to buy it, return it, and waste my time on something I know that has a great chance of failure.
I also have Logitech Z-5500 speakers that I would like to use with my Macbook. Would a toslink to mini-toslink cable work?
Thinking about getting one to go with my m4500 which is on order. Reviews seem ok though some complain it's bulky and other complained the release mechanism wasn't great. Worst was that someone said their comp wouldn't boot when docked.
Can anyone share experience and/or high res pics of what one looks like?
I bought a generic 2 HD sata2 RAID1 enclosure based on the chipset Silicon Image SteelVine 5744. It can be used in USB or eSATA2. This embedded chipset (named SiL5744) is known (understand "claimed") to auto-handle Sata I/II and host sata2 controllers that not support the port multiplier feature. The HD are two Samsung F1 1To. There's no jumper to rollback to SATA 1.5Go on them, you can only do it by flashing the HD's bios, however we don't need to do it as I wrote just before, the SiL5744 supports SATA 3Go natively.
The enclosure works pretty well with USB, but *not* in eSATA : the E6500 freezes/hangs just after the POST step (a potential driver issue with the installed vista 64bits is not the reason then). As soon has I disconnect the eSATA cable, the system recovers and continues as normal.
What I've tried/done so far :
Both E6500's BIOS SATA mode AHCI and IRRT mode were tested, Intel Matrix driver and software was updated to the latest 18.104.22.1687 version (AHCI and IRRT), The SiL5744 chip was upgraded to its latest firmware as well (in case of...)
In order to verify the esata cable, the HDs and the enclosure itself, I succeed to :
- Use the enclosure's RAID1 feature when using the USB connection, I could partition,format, and read/write on the logical volume - directly connect *one* HD (Samsung F1 1To) to the E6500's esata port -(I have a sata2esata cable), Vista installed it and I was able to use it as normal, even the hotswap feature seemed to work fine (I unkindly removed it). I could so test both HD individually this way... On the enclosure hardware side, everything looks fine then.
An IMPORTANT thing : The E6500's ICH8/9-M sata host controller seems to support the Port Multiplier feature *ONLY* on sata port 0 -as a bubble message from the Intel Matrix soft sometimes shows up-, but this is exactly where the internal HD is plugged on the motherboard I found nowhere you can change the internal sata port ID (switch,bios,ect...). I think this is the key of the problem that seems to be a dumb port conflict, because the esata port is in fact the port sata 4 (the DVDRW drive is sata 1, dock's esata is 5 for instance). If somebody knows how to swap the sata port ID, I think I won't be toasted !
I own a Studio 1555 and i am having this peculiar problem with my onboard LAN connection. The LAN cable is connected to the NIC, yet it is displaying cable not connected. I need to reconnect the cable (remove it from the NIC and reconnect it) and it displays cable is connected and the connection ensues. Once i restart the machine, the same is displayed and i will have to reconnect the cable once again in order to get connected.
I do not want to reconnect the cable every now and then, when i reboot the laptop..
I bought a new laptop HP Pavilion g7.I got Ralink RT3290 802.11bgn Wi-Fi Adapter but my problem is that I can only connect to 802.11 n network and I can not use 802.11 g wifi.When I trying to connect 802.11 g wifi it says limited can not download any webpage but I should use it with this Ralink 802.11 bgn adapter yes? I have already updated the Wifi adapter but didn't work I turned off every firewall and antivirus software and I have already writing by manually IP address ,subnet mask etc...I got window 8 software. what has windows 7 I can connect without any trouble to 802.11 g wifi! I'd like to use 802.11 g because the signal strength is stronger than 802.11 n .I can receive the signal from 802.11 g wifi network somehow.
