Re: Does not start
Did you recently add a memory..?If yes Then remove it because a frequency mismatch can cause this problem...Another possibility is that the Memory may be oxidized at the end..If this happens then remove the memory and rub the edge(the side which you plug into the slot) with an eraser and then put it back...There's another possibility that the memory slot on the motherboard may be damaged..So try plugging the memory into the other slot and try again...Let me now what happened...

I would guess two things, 1. you have a bad connection on the DIMM socket or on the DIMM fingers. You can try to clean the connections. 2. You have a bad DIMM or the wrong speed DIMM.... check to insure you have the right memory.
Doesn't specifically mention the 53.21 error this is the closest they come so you will know it deals with the ram anyway

you may do follow steps
1) take out the memory change memory slot each onther (if there are two memory sticks) and clean memory pins and slots, then turn it on or change another memory to try.
2) take out wireless card then turn it on, if ok the wireless card fail.
3) still noting shows, check your adapter DC jack into DCjack socket their connection. it could be related this trouble,
if adapter fail which can not charging the battery and turn on laptop, if DC jack socket connection is not stable the same problem could be occured
hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question
Your laptop's memory is malfunctioning. To remove the memory, power down your laptop.
Turn it over and you should see a cover about the middle of the back. Open it and there you should see the memory. You may or may not have more than 1 memory Dimm. Also there are 2 slots. The bad memory is the one in the first slot. Take it out and put the other in it's place. the laptop should boot up ok, but slower because of the missing memory which you should replace.
If you get the same message, replace the memory with the one you took out, then reboot.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it. Thanks, Joe
I had the same problem and could not find the pictures either. I still figured it out, so here are more detailed instructions. Please use a combination of the previous instructions and mine. This worked for my computer, but I can't guarantee success everytime since I have only done it once. Just do the best you can.
-Pull off the memory cover on the back of your computer.
-Now, take out any memory cards that are present.
-Look at the circuit board under where the memory was. You should see a rectangular black plastic sticker.
-Pull the sticker up.
-Look VERY closely at the circuit board under where the sticker was. You should find two soldering points close together that are labled with "B500."
-Now put one memory card in the slot that is furthest from the circuit board. DO NOT put a memory card into the inner-most slot at this time.
-Carefully hold a very small straight screwdriver over these two points and turn the power on to your computer.
-The Toshiba boot up screen will appear.
-Continue holding the screwdriver over the two points until the Toshiba screen goes away.
-When the screen goes away, pull away the screwdriver.
-Turn the computer off.
-Put the black plastic sticker back in place on the circuit board.
-Put all memory cards back in the memory slots.
-Put the memory cover back on the laptop case.
-Turn the computer on.
At this point I was asked to start windows normally or start using repair wizard. Normally did not work. So start windows using the repair option. It took about 10 minuts for windows to finally open normally.
100% success in my case! Please be careful when doing this repair because I do not know what damage could be done if you do it wrong. But, after 2 months of not using my laptop, it is finally back in operating condition!
I think you might have a faulty memory module. The socket where you
push the PC card is not the Socket 1. I think the notebook is
complaining about the Memory socket witch you can access if you remove the memory cover(click for details)
on the bottom of the notebook. Try reseating the memory module, remove
it from the socket and install back. Make sure the memory contacts are
clean and not oxidized; clean them with an eraser if they oxidized. Try
moving memory from one socket to another. If you have two memory
modules installed, remove them one by one and test the notebook with
only one module installed. Find out which module is bad.
