Satellite S50 won't POST after memory upgrade

Hello, all:
I just purchased a brand-new 8gb Kinston memory stick (KTT-S3C/8G) for my one-month-old Satellite S50 (S50-ABT3N22). Slot A contains the standard issue 4GB stick that came with the unit so I put this into Slot B. When I install it, the machine refuses to POST. Kind of odd. So, I swapped the DIMMS and it still doesn't POST.
Any idea what's going on? The DIMM is brand-new. On the Kingston label, it also has a Toshiba PN PA5037U-1M8G.
Any info would be helpful. I'm hoping the DIMM isn't bad.

no worries. Lots of folks miss the fact that their computer is spec'd with the "L" which stands for low voltage type of ram. That's what the "L" stands for in the DDR3L 1600MHz. You can likely run faster ram (or overclock to a faster speed if the bios allows) but you need to adhere to the voltage requirements, as well as the timings.

Dual 867 MDD won't sleep after memory upgrade

Since yesterday my PowerMac G4 Dual 867 MDD has become insomniac. What changed since yesterday is that I installed an additional 512MB of RAM. So far as memory is concerned, there's the factory-installed 512 Infineon module; a second 512MB Kingston module (installed about a couple of years ago, and has been working fine ever since); and a third 512MB Kingston module (the one I installed yesterday) for a total of 1.5GB.
I am aware that sleeping issues can arise for all sorts of reasons (inc. USB peripherals) but it is pretty obvious that in my case the problem is caused by the memory upgrade.
The symptoms: Once I click Sleep on the Apple menu, I can hear the sound of the hard disks spinning down, but the rest of the box remains fully powered. The screen freezes and the computer has to be manually switched off, as the mouse cursor disappears from the screen and the keyboard becomes completely unresponsive.
So far I have tried the following: I have reset the PRAM (no luck there), and have tried switching memory modules to different sockets (basically, the single remaining free slot). I apologise in advance if that second troubleshooting routine might portray me as an ignoramus; I have a good understanding of things but cannot claim to be an expert.
I am a extremely frequent user of the sleep mode, and this issue has taken away from me all the pleasure that comes with a coveted (and long overdue) memory upgrade. I would deeply appreciate any help in resolving this.
Many thanks

Dear Dave,
Many thanks for your prompt response. I ran Rember (Amount of memory to test: "All". All other boxes unchecked - I was running other apps at the time). I cannot understand the results from the log, but I didn't get any feedback at the end of the testing. I attach the contents of the log below:

Satellite A200 PSAEOE won't boot after memory upgrade

Hi, I am first time here.
I have bought a Toshiba A200 PSAE0E-03J02JDR with 2 GB ram memory. I bought a pair of Corsair ram (2*2GB VS2GSDS667D2). After I installed the memory the computer won't boot. I have intel 945 chipset, which is capable of 4 gb (manual page1-2). The bios version is 1.8 from 2007.
Can anyone help me, please.
Message was edited by: ovidiu marian

Hi
The A200 series supports different chipsets;
Intel 945PM
Intel 945GM
Intel 943GML
As far as I know your notebook supports the *Intel 943GML* chipset and this chipset supports max 2GB RAM.
Take a look in your notebooks user manual *Page 18.*
Summery: 4GB RAM are not possible and therefore your notebook does not boot up.

890FXA GD-65 won't POST after PSU upgrade

Two days ago, I upgraded my PSU from a 750W Corsair to a 1000W Cooler Master (in preparation for a second 6970 coming in on Tuesday). After switching them out and powering the machine on for the first time with the new PSU, it seemed to power on normally, but I wasn't getting any video. Thinking I may have not connected the GPU's power correctly, I powered down the system and double-checked my connections. Well, there weren't any issues, so I tried powering on again. This time, all I got were spinning fans (including the CPU fan), HDD spinning up and two phase LEDs blinking. Didn't even get the usual startup noise.
I spent my free time the last two days testing each component that I could in an older AM2+ system (this means the CPU, GPU and PSU), and they all checked out fine. I even tried powering the 890FXA with my old 750W PSU with the same results and checked the board for bad caps and found none.
The only thing I couldn't test is the RAM (besides reconfiguring the sticks in the DIMM slots, testing each stick individually, etc.), since the AM2+ board only takes DDR2 and the 890FXA only takes DDR3, so at this point, I'm thinking it's either the RAM or the board itself. My question is - before I go out and buy a stick of DDR3 to test or RMA either the board or the RAM, is this behavior consistent with a fried board or bad memory? I've never had RAM go bad on me before and the only fried mobo I've ever dealt with wouldn't even power on. Would bad RAM result in failure to POST, and moreover, what's the likelihood of all three sticks going bad at once?
Thanks for the help.

A number of PSU calcs said I'd be cutting it close on the 750, especially since I was planning on adding another two 500gb caviar blacks to my RAID setup as well, and the 1000 was on sale at the time so I figured I'd rather upgrade now and spend less.
Anyway, yes, the CPU power connection was fine, I did do a CMOS reset and I tested the board outside the case. I even tested it without a GPU, CPU and memory, all with the same exact results. Testing it without memory made me realize it very well could be bad memory, but last night I had a friend lend me a known working stick of DDR3 with no luck.
I'm pretty much convinced it's an issue with the board itself now, being that all the components that matter have been tested independently and checked out alright. Probably time to get an RMA.

PC won't boot after memory upgrade (on MSI P45D3 Platinum)

I am having a problem on my MSI P45D3 Platinum motherboard system (Dual OS: Win XP and Win 7)
Until recently I was running it on PATRIOT 2GB (2x1GB) 1600MHz DDR3 PDC32G1600LLK memory (CL7) and all was fine, though running only at 1066MHz, since I couldn't tweak the settings (latencies/voltage) in order for it to run at 1600MHz.
I wanted to add RAM but since I couldn't find the same type anywhere in my town, I decided to go for PATRIOT 4GB (2x2GB) 1600MHz DDR3 PSD34G1600KH Signature Line (CL9). However, the system never booted again (blank screen, no signal sent to monitor) after adding the two new sticks of RAM! The new RAM is working fine when I remove the old and vice versa, so I know it is not a case of defective sticks.
I must mention that I cannot fiddle with the RAM timings because I cannot even reach BIOS!
Any help will be most welcome!

Mixing different memory modules is always a gamble and likely to cause such problems. Identical modules should be used for best results.
In many cases, you can set what you want regarding memory configuration, getting the RAM mixture to work stable will simply be impossible, even though there is no defect.

HP 8710W Won't Post After Firmware Upgrade

I was having power saving issues with my 8710W so I decided to try updating the firmware.
After the firmware update the laptop now powers on and beeps once but there is no hard drive activity and no video output.
I tried restoring to the oldest and newest firmware by creating a bootable floppy with the firmware using the tool on the HP website. I then powered on the laptop while holding win+F. The drive reads for about 2 minutes and then about a minute later the laptop reboots but nothing.
I also tried resetting the BIOS setting by booting up while holding all four arrow keys. Nothing changes.
I contacted HP support but they won't help because there is no serial number listed on the bottom of the laptop.
Is there anything I can try?

Hi,
Which media did you use to create a bootable one? disc, or floppy, flash drive?
If you can make sure the bootable media is available, I advise you keep tapping F9 key when you power on the unit ASAP.
Thereafter you have entered into advanced boot option, and choose the corresponding boot device attaching your media to update the BIOS.
Good luck !

Satellite A105-S2001 wont boot after memory upgrade

I just tried to upgrade my memory from 512mb to 2 gb using 2 1gb memory chips from crucial. When i insert both memory chips at the same time my laptop wont boot, it'll attempt to but stop in the middle of the process and try again 5 or 6 times. Nothin shows up on the screen. The same thing happens when i put only one 1gb chip in. When i put my old 512mb chip in and one 1gb chip the computer boots but only recognizes 960mb or ram. i also updated my bios.
thanks

Sounds like incompatible memory. Fortunately, Crucial is very good about honoring their compatibility guarantee so you should be able to get them exchanged. You can get very strange results with incompatible chips due to the differences in timing specs. That would account for what you're seeing. I assume it works normally if you have just the original 512MB chip in place.

Mac mini won't boot after RAM upgrade.

Tried installing new RAM in my Mac Mini, 512MB stock to 2GB of Crucial. Followed the directions to a T, grounded myself the whole time.
Things I've tried so far:
1. Resetting the PRAM, no luck.
2. Holding option at start-up, shows no icon.
3. Holding shift, no luck.
4. Holding X, nothing.
How do I get it to accept a CD if it won't boot?

Welcome to Apple Discussions!
You clearly have a problem, but you don't describe exactly what that is other than that your mini won't boot after the upgrade. What happens when it starts up? Does it attempt to start and hang up on the grey or blue screens, or does it start beeping at you almost immediately after you try and start it up, and also flash the power light?
If the former, then you may have dislodged a connector while working inside the system, in which case opening it up and checking that everything is firmly connected would be the first thing to do. If the latter, then the beeping/light flashing is the system telling you it has failed the power-on self test and the pattern of beeps/lights indicates why. In your case likely the system can't find workable memory. In that instance, opening the system and ensuring that the RAM is firmly and fully seated would be a good step, and if the mini continues to fail, then replacing the new RAM with the original to test that the system will then start.
It is not likely that anything had damaged your MacOS install in the process of upgrading, thus normally no reason to need to boot to CD as a result of a RAM issue.

Email links won't open after ipad upgrade to 7.0.4, any help?

Web links in my emails won't open after ipad upgrade to ios 7.0.4, Any help with this issue would be appreciated.

Have you tried restarting or resetting your iPad?
Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after It shuts down, press the On/Off button until the Apple logo appears.
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds).

IMessages won't open after Mavericks upgrade

iMessages won't open after I upgraded to Mavericks. I keep getting prompted to "enter the keychain password," but I never created a keychain. I never used it before the upgrade, and I skipped the step during the upgrade because I did not want to use keychain and it was an option to skip it during set up.

HI,
The OS X Mac have been using Keychains for a long time.
In the Applications/Utilities folder open Keychain Access.
This should show you at least two keychains.
The Login one for your Mac User account and the System one.
Generally speaking the Keychain keeps the passwords used by various apps and it needs to be Open.
In most cases the Login password for the Mac Account user is also the password that opens the Keychian when the computer is started up.
As each Mac User Account owns it's own Keychain there can be issues when you drag an account from one computer to another rather than using Migration Assistant.
i.e. you might Own it on one computer but not on another.
In the Finder > Go Menu hold down the ALT key and select the Library that appears.
In the library navigate to Keychains.
Click to highlight the Login one.
Now use the CMD and i keys together (Get Info)
At the Bottom unlock the padlock
Highlight the name that has (me) next to it (it should be your Shortname).
Once you have highlighted this use the cogwheel item at the bottom.
This should be greyed out but saying "Make you (Me) the Owner."
You should also have Read and Write permissions like in the Pic.

K7N2GM-V won't POST after shut down

Hi all.
I just did my first build on a K7N2GM-V and it won't POST after I shut down. When I hit the power button, PSU does not turn on, fans do not turn on, nothing happens. If I wait about 10-15 minutes, then it will POST and boot normally to my XP Pro SP1. Nobody seems to have had this problem and I am stumped.
Could it be due to my power supply? My PSU is the one that came with the X-QPack, which claims +3.3V(18A), +5V(22A), +12V(20A), -5V(0.3A), -12V(0.8A), +5VSB(2.0A). I don't have a spare PSU to test this with.
Any ideas? Please let me know what additional information might be needed.
Thanks.

Satellite A100 shuts down after memory upgrade

Consider me as 1 of the thickie bunch.. Not even sure wot im talkin bout but here goes n e way...........
Have a Satellite A100 570 ( PSAA2E)..........
Have tried several different online sites lookin for memory upgrade. Didn't have the witt to use toshiba site...... Ended up going with Crucial.........
Ran diagnostic on laptop and was sent the module a needed.or so i thought....... wrong 1 or 1s as i bought 2 x 1G modules in order to " double up".....
Got my money back as they were not compatable with my system.. something to do with density problems....
Tried company called OFFTEK........ they seemed to know what they were talkin about....... I have from Offtek. at present a..........
200 Pin 1.8v DDR2 PC2-4200 SoDimm....... but Toshiba have recommended below......
1GB PC2-4300 DDR2 Memory (533MHz)
Part Number: PA3411U-2M1G
1024MB (1GB) Memory PC2-4300 DDR2 (533MHz)
Theres an obvious difference ...... 4200 and 4300. But im not sure if its a significant difference........... or what it means
Have updated bios to most recent version and basically updated everything toshiba had to offer for this model...........
Ran EVEREST and it recognises the 1G module but when i take out the original 512mb module the laptop starts for about 3 seconds then shuts down...
this repeats about 5 times then complete shutdown.....
I dont like opening the back cover too often but this is the 3rd module ....
Not sure whats meant to happen if the module is working...i.e start up message..not sure if windows recognises 1G module....
Would it be safer bet to send Offtek module and stick with toshiba option.....
Thanks in advance.....

Cheers R2........ suppose at this stage i could start rhyming off a load of star wars lines but uve probably hears them all before.......
N e way......... checked out the link u posted..........very useful......
The module described is identical to what i have.............As with previous reply ( above ) im not sure what to do.........might take up Offteks offer of replacing the module but slightly concerned it might have same outcome......Still not happy bout opening the cover so much........nut needs must i suppose

Performance degrades in Probook 4540s after memory upgrade

Hello. I've installed recently in my Probook4540 two Kingston memory modules (2x8gb ddr3 1600 CL10 240 pin). Ever since I did this, Windows 8 takes much longer to boot and performance has significantly dropped. But, if I only place one of the two modules, or the original 4GB module, Windows runs at normal speed.
I think it's a BIOS problem, as I've just seen this very same error in other brand's laptops, for example here
http://superuser.com/questions/379970/laptop-is-incredibly-slow-after-ram-upgrade
I've got the latest available BIOS version installed (F31 26-SEP-2012).
Thank you.
This question was solved.
View Solution.

I actually started a case under their Business division. I first received the generic/automated response from HP saying that the laptop can only take 8GB of RAM max. They actually sent me a link to an official HP 4540s specs and it actually shows 8GB max. BUT, I never saw that PDF but used the one linked on their shopping site under business section and it shows maximum of 16GB of RAM. I explained all of this to a supervisor and they decided to escalate the issue to Level 2. I'm still waiting for a final decision. I'm worried they are going to try to replace the motherboard. I truly believe this is a BIOS update issue. Like I said the 4540s i3 we have can take the 16GB of RAM with no performance decrease. Only the i7 one is slowing down to a crawl. No error messages anywhere.

MacbookPro will not wake up from sleep after memory upgrade

I am restarting this topic as I have read thread after thread (many years old) and they all just die off with out any definite solution.
I have a 13" Mid 2010 Mac book Pro which originally came with 250gb HDD and 4gb memory
I have recently upgraded to a 256 SSD and a 1TB HDD optidrive replacement along with a 8GB memory upgrade and I am now running Lion 10.7.4
If I close the lid and open within approximately 1 minute it will wake up quickly as normal, if I leave it asleep for a minute or 2 it will not wake up with out holding the power button for several seconds and then I still need to wait a several seconds for it to respond and actually wake up. Sometimes I will need to completely shut down and restart. If I wanted a computer that takes forever to wake up I would have a PC!
The last thing I upgraded was the memory so I am sure it is the cause of the sleep problem and not the SSD conversion which was working fine with the original 4GB mem before upgrade.
I have read about resting the PRAM, resetting PMC as well as executing a line in the terminal, but all of these seem to have variable success. I have tried every thing but using the terminal to adjust the hibernate mode setting as I am not proficient with terminal and don't actually understand what changing this setting does (sudo pmset -a hibernatemode 7).
Has anyone resolved this sleep problem and what did you do? I would greatly appreciate some knowledgeable insight on the hibernation settings, and what running the line in the terminal is actually doing... even better what is the default so I can change it back if it doesn't resolve the problem.
A simple memory upgrade causing such a issues is very irritating.... Any help would be greatly appreciated!

But still, the sleep issue persists, so it is a more subtle timing issue. I upgraded my MBP with a Corsair 8GB kit ( http://www.corsair.com/us/corsair-mac-memory-8gb-ddr3-sodimm-memory-kit-cmsa8gx3 m2a1333c9.html ) and it indicated it had 9-9-9-24 CAS timing. It has worked flawlessly till now. Note that my Mac is a Late 2011, whose memory runs at 1333 MHz.
As far as I can tell, the 13" Mid 2010 models used 1067 MHz memory with 7-7-7-20 CAS timing: http://www.corsair.com/us/corsair-mac-memory-8gb-dual-channel-ddr3-sodimm-memory -kit-cmsa8gx3m2a106c7.html

MacBook Pro won't POST after 10.6.8

Hello All,
After installing 10.6.8 last night on my 4.1 MacBook Pro, it won't POST. The sleep indicator light comes on briefly and I can hear the optical drive spin a bit, and then it just shuts down. No display, nothing.
Any troubleshooting tips would be greatly appreciated.
I took a quick video of what it does. Here is the YouTube link to the video:
