Question about Acer Aspire T135 PC Desktop

4 Answers

Dead Acer desktop

Have a year old Acer. Not used a lot -kids computer. Had a little trouble powering it down a little while ago. Now won't boot at all. No fan, no hard drive, no noise. I took off the cover and front panel to check the connections and power button. When I push the power button without the front cover button, the power indicator on the top of the PC front panel lights up but still no noise or anything. If I'm getting the LED light, does that mean it can't be a power supply problem? Acting like it just isn't getting any power since the fans don't jump or anything. Any ideas on what I should do to fix this or figure out what to do next? Hate to trash it since it's so new. Shouldn't be having problems already.... Thanks, Debbie

    Thanks for the help! I reseated the connectors and still nothing. The fan on the power supply doesn't move. All I get is the tiny led power light and that's it.

    Anything else I should check?

    Thanks,

    Debbie

    Thanks for all the suggestions!

    I don't really know if the light is brighter or dimmer. Kids' computer so I didn't use it to notice the light before.

    Moved the jumper. Not sure what sandrew meant about the battery being flat. The top of its surface is flat but it looks normal. Could do the paperclip thing since there are lots of black wires. It's the kind with like 25 pins or something. Just one green but lots of black.

    Don't have another computer to move it to.

    Thinking of calling today to see if I can get a replacement power supply relatively cheaply and swap it out. Sounds like it's that, but seems REALLY early for it to have died. Kids didn't abuse the switch, though they were using the power switch to put it to sleep and it started seeming flakey a little while ago. Not waking up when we pressed the button again. Had to kill the power and then reboot a few times. Does that mean anything?

    Thanks,
    Debbie

    I meant I couldn't try the paperclip thing. Which black wire would I use?

    Hi,

    Took it in to someone to check the power supply yesterday. He said the power supply was dead. Was going to order a new one, but then he said he'd check and make sure everything else was OK by putting a power supply in my PC. Well, it KILLED his power supply!! He said that happens sometimes when there's a short on the motherboard, but seems really odd that there was no noise, smoke, nothing. Just didn't start and then when he used his tester thing on the new power supply it said it was bad. Does this really happen? If so, does that help figure out what's wrong with it? Am so frustrated that it happened on a year old PC assuming it's a big problem and I need a new motherboard.

    Also, if you are familiar with this scenario and have had this happen before, are the components (RAM, hard drive, etc) usually OK or do I have to worry that everything shorted out? No signs of damage inside -- nothing dark or smokey or burned or anything.

    Am going to call Acer Mon just on the long shot that they'd do something since it's so close to the warranty period, but thought I should check with you all to see what you think.

    Any thoughts?

    Thanks!!

    Debbie

    PS I am in the US and I checked for a voltage thing since the kids have accidentally bumped it on a old PC, but it's covered with plastic and there isn't anything on the back that could be inadvertently changed that I could see.

    had the same problem with an acer computer. It turns out to be in the dc jack that is soldiered to the mother board. If the kids moved it around alot they might have loosened the soldeiered joints. You mioght need to repacee the dc jack or you might be able to have it re welded. The part runs any where from $20 to $50 and then about $100 to have it installed.

I would agree with other posts to it being the power supply, but just try disconnecting from mains and taking the side off pc again and check that the cmos battery(disc shaped CR2032) is'nt flat. Also locate CLRCMOS or JBAT1 terminal to clear cmos by putting jumper from pins 1-2 to pins 2-3, then back to pins 1-2 again if it's a JBAT1 terminal, if a CLRCMOS or CLR or similair, just put a plastic jumper cap across both pins to short it, and try again. Best to try cheapest options first, but is does sound like a PSU problem, as sometimes is shows active but cannot power the processor.

Hi dmorley it's hard to diagnose your symptoms However let?s try the power supply in another Compatible unit first, if it works well then that Eliminate the power supply as a suspect. If it Doesn?t work, then you may need a new Power supply.try doing this first okay.

Hi, "No fan, no hard drive, no noise" means the motherboard is not getting any power which is kinda out of sync because you are getting a power on light indicator. To confirm if your power supply is ok, check if the fan inside the power supply is working. you can look at the back of the casing, if it is turning then psu is ok. Try to reseat the power connector from the psu to the motherboard, some of the pins may not be in perfect contact but others are that's why the led lights up, but the mb is still dead. Please let me know how it works out for you. Regards.

    Hi again Debbie, a question pls is your indicator light as bright as before or dimmer?
    Also you might want to check the back of the unit where the power cables go (pls make sure it is unplug) Try to see if the power supply has a voltage selector slider switch. It it has got one it should be set to 110. I was just thinking that you might have one of those power supplies with 110 and 200v settings. This is of course a shot in the dark cause all indicators point to a defective power supply. Good luck.

    Debbie by 110 I am assuming you are somewhere in the states and not anywhere else that uses 220 like Europe or Australia. Otherwise please leave it as it is.

Acer aspire just quit with a grinding sound


Yes, the HD might make that sound and, if it did, it's dead. When that happens the computer will usually power on but it won't boot because it can't; if the disk is dead there's no way for the computer to load the operating system. If you have a bootable CD (the recovery disks that come with most desktops are bootable) then you could try putting that in to the CD drive and booting the computer. If the computer boots up with a CD but not with the HD, then you have a dead HD.

Gateway GM5472 won't boot no power


No power and won't boot suggest a power supply problem in the tower--it is listed as a desktop unit.

What is common on a lot of units (computer towers, TV sets, you name it) is the stand by power supply which is on 7/24 fails.

The most common reason is filter caps dry out because cheap ones and ones rated too low a voltage are used.

The beauty of this is if the power supply is removed and opened you will be able to SEE the bad ones.

I will attach a photo of bad caps--tops which should be perfectly flat are puffed up from a little to a lot and or brown material is seen at top and bottom of the cap.

I have fixed many towers (desktop units) and other equipment with this problem---most of them at first had to be turned on a few times to get them to come on--it gradually gets worse until it will not make it on.

If bad caps are found you can usually buy a replacement supply at a reasonable price or replace the puffed up caps (seen as many as 8 bad in one computer tower).

This answer is based on the information you provided in your question and the answer from personal experience.

My pc was working properly when I turned it off. Upon returning I powered up my pc (HP 805n) but it will not turn on. The green light in the back of the pc is steady, but no response. I've own the pc...


to trouble shoot,

open case and disconnect all cables except power supply.

if the computer starts up okay, then shut down and connect the cd-rom then startup. if that's okay then connect any other cables . if any one of the parts are defective you will find the stinker.
if the computer still won't go, try another power supply/
if that's okay, then the board might be bad

ACER Aspire L100 Desktop is dead?


If the hard drive is OK then you can remove the hard drive from the desktop case, and insert the hard drive into a USB 3 1/2" hard drive adapter case, this should come with a power adapter. These are available at your friendly computer shop.
Boot up the laptop then plug this USB hard drive adapter into the laptop's USB port. The laptop will see this as an external USB hard drive. You can open the various folders and files on this external drive and copy the folders and files to the laptop.
You can delete the Windows folder and Program Folders on this external drive to free up disk space and use this as a back up drive etc.
If you are not sure how to remove the hard drive and install it into an USB hard disk case, then I suggest you get a computer savy friend to help you.

Acer Power FH will not boot Windows XP Pro


Well your explanation was clear but your should've not ruled out the hardware issue. if both computer suffered the same problem at the same time the problem could be within the Desktop itself. I have experienced the same problem with my HP when I move to my new house after 5 years. What happend is that during transportation the vibration lossened up the parts inside your computer. So what I did was I reseated all the parts inside the desktop and reinstalled Windows XP. Till now I have never had any problems yet.

No power when i turn on the computer and everything is plugged in


Most likely it is a motherboard issue. I have seen a lot of these mobo issues in my shop recently. You can inspect the mobo yourself.
Failure of motherboards is usually due to breaking capacitors. A few years ago a capacitor company stole the "recipe" for making capacitors from another company and tried to make their own, unfortunately they did not get the ingredients right and the capacitors started breaking after 2-3 years of use. They sold these capacitors at very cheap prices and a lot of computer companies and power supply makers bought them. This is easy to diagnose. Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything. The dead giveaway is the fact that you are not getting a monitor signal and if you listen to your computer as it starts up, a few of the devices may not start (hard drive, etc). A failed video card will also give you "No signal message", but the computer should sound normal when starting up. Mobos are usually expensive to replace because the computer makers have them made especially for them and only order so many. They usually do not have a lot of extras laying around. There are a few companies that will repair broken capacitor issues. Hope this explains why they can fail. They (mobos) can also fail if overheated (like when a case cooling fan fails), the cpu is overclocked and not cooled down (which raises temps), the power supply fails or by lightning and power surges. Also if you add a bunch of extra components without upgrading the power supply you can suffer underpowered situations.
